New Mexico State University Department of Geological Sciences Newsletter 2014 Contents Alumni Support Whether it’s scholarships, colloquium, operating expenses, a new field vehicle, or research support, our Alumni are essential to having a strong, vibrant department. This is particularly true during times of University budget cuts and increasing competition for Federal funding. Please visit <http://geology.nmsu.edu> to find out how you can help NMSU Geological sciences today. Department News Our 2014 cohort of incoming MS students are from Colorado State, Illinois State, Sacramento State, U. Wyoming, and NMSU.

Dr. Hampton and his student Mark Brown presented at the Annual Meeting of GSA in Vancouver, Canada. 1 Danny Stokes (BS ‘79) Joins the Geological Sciences Hall of Fame Danny Stokes joined the NMSU Geological Sciences Hall of Fame this month. Danny was honored at a luncheon at the Farm and Ranch Museum on November 7, 2014. Danny retired in 2010 after serving over 30 years in the oil and gas industry where his specialty was coordinating drilling fluids. He spent the majority of his career with Baker Hughes, and had the opportunity to work in Angola and Kuala Lumpur, among other far flung localities including Kuwait, Viet Nam, and Equitorial Guinea. During a slide show presentation at lunch, Danny told amusing stories that highlighted his ability to improvise solutions to tricky problems that arise when working in remote international sites. Danny Stokes at the Alumni luncheon with his wife, Ida. He highlighted the importance of workplace safety. He also emphasized to the students that writing skills are essential to not only getting a job in the first place but also to effectively communicate with your coworkers and bosses during your job. Congratulations, Danny, on an excellent career and welcome to the Geology Hall of Fame!

Consider donating to the department, and as always, contact us with job or internship opportunities for current students or recent graduates. 4 Alumni Support Opportunities Alumni Giving can be made through the NMSU Foundation. We are currently asking you to consider donations for two urgent needs. The first is that graduate research is costly, and traditional avenues of support for student research are becoming even more competitive. We have set up a new fund that will be used specifically to fund student research, and we are calling it the “Graduate Student Research Grant Fund.” Our goal is to raise $2500 for each of our ten graduate students for the 2015-2016 academic year. We welcome full or partial funding, perhaps $50, $100, $250, or $500. Direct donations to the Graduate Student Research Grant Fund online or in the memo line of check (see below). Another urgent need is our aging fleet of Suburbans. The 1982 was put to pasture a few years ago, and now our ‘96 and ‘99 Burbs both have >160,000 miles on them and the repair costs are starting to add up. As you likely know, these vehicles are essential for field trips, field conferences, and student field research. They are getting even more mileage on them now that we have instituted a mandatory field trip for all of the 111G Intro Geology classes. A new field vehicle will cost approximately $50,000 and we have already raised $11,000 towards this goal. Please consider helping us! Donations for this need should be directed to the Geology Field Teaching/Research Fund (#102194). As always, general contrubutions can be made to the Department via the General Gift Fund (#102190) All donations are tax-deductible and can be made in two ways: 1) Online donations can be made via the NMSU Foundation at http://giving.nmsu.edu/giving.php. Please click on the link “Tell us how you want your gift applied” and enter Department of Geological Sciences followed by any specific fund you might want to support (see above). 2) Checks can be made out to “NMSU Foundation” and include the Department and fund number in the memo line or in an accompanying letter. Mail to: NMSU Foundation, Inc. Dove Hall, Room 212 1305 N. Horseshoe Dr. PO Box 3590 Las Cruces, NM 88003-3590 Let us know if you would like to be recognized for your donations in a future newsletter. As always your support is greatly appreciated. Please contact Jeff Amato (Chair of the Alumni Relations Committee) by email (amato@nmsu.edu) or phone (575-646-3017) if you have questions. 5 Faculty Profile: Dr. Jeff Amato Amato continues his work on the Precambrian geology of New Mexico and the Mesozoic evolution of the Arctic region. The recent GSA Special Paper on the geology of Seward Peninsula, Alaska, featured three chapters on which he was either first author or a co-author. He is finally wrapping up his manuscript on a suture zone Ryan Bright (MS 2012) had his research published in Lithosphere in June of 2014, and his photo of 1.1 Ga diabase dills in the Salt River canyon of Arizona was chosen for the cover. This is the second Lithosphere cover for a student-authored paper in Amato’s group, following Evan Kochelek’s (MS 2011) 2011 article on the Valdez Group. in eastern Russia. He is working with his former graduate student Tara Jonell (MS 2010); on publishing her work on a Paleogene caldera in the Burro Mountains. His remaining time is spent trying to write up mountains of unpublished U-Pb zircon ages from projects spanning the last 10 years. In April, Jeff ran his first marathon at Big Sur in California. Stephanie works at the Asombro Institute for Science Education, a local non-profit, and also ran a marathon this year, in Las Cruces. Their daughter, Sofia, is in 1st Grade and will turn 7 in January. Wesley is now 4 years old and is the unofficial talisman of the geology intramural soccer team (see below). Zircons! Bright, R.

In other Amato Research Group Alumni News, Eric Gottlieb (MS 2008) is nearly finished with his PhD at Stanford University. He is currently an intern at Exxon in Houston. Tara Jonell has spent two field seasons in the Himalaya as part of her PhD research at LSU. Sean Gaynor is working on his PhD at UNC-Chapel Hill. In August, Amato attended the wedding of former graduate student Matt Bogar (MS 2005) in beautiful Taos. Although Matt is no longer working in geology, he is gainfully employed and enjoys climbing and telemark skiing. See page 4 for more ARG Alumni News. Amato played on the co-ed soccer team, started last year by Gabby St. Pierre (BS 2014). This year, the team has scored in each of their four games, and last week managed a resounding 6-0 victory, the first ever for the Continental Drifters. 6 Faculty Profile: Dr. Reed Burgette Dr. Burgette enjoyed a good first year at NMSU. He enjoyed starting to learn some local geology from the Precambrian to Quaternary through teaching Survey of Geology, Tectonic Evolution of North America, and Neotectonics. A highlight of the Neotectonics class was a field trip to survey a portion of the Alamogordo fault scarp along the rangefront of the Sacramento Mountains. Chris Crosby from UNAVCO joined the class to demonstrate the use of a terrestrial light detection and ranging (LiDAR) instrument. They surveyed several million points over two days and used the high resolution topographic data to assess the fault scarp morphology and age. Reed’s research in neotectonics has expanded into southern California where many active faults pose a major seismic hazard to a large population. He is funded by the Southern California Earthquake Center to measure uplift rates associated with active faulting in the western Transverse Ranges over the past century using tide gauge and leveling observations. This project involved a trip to Washington D.C. over the summer to gather data from the national archives. Reed is also starting a project to better measure the late Quaternary slip rate of the Sierra Madre fault, which bounds the northern edge of the LA metropolitan area using high resolution topographic data Reed Burgette with his son Rowan, hiking in Tasmania in 2014. and modern dating techniques. This project will be the focus of Austin Hanson’s M.S. thesis. He looks forward to applying these techniques to study active faults in the southern Rio Grande Rift and elsewhere. Field trip to the Sacramento Mountains. 7 Faculty Profile: Dr. Brian Hampton 2014 was a busy year for the Basin Research Lab at NMSU. Hampton published some recent findings from MississippianPermian strata of the Farewell subterrane of southwestern Alaska in the journal Lithosphere with former graduate student Matt Malkowski (currently pursuing PhD at Stanford Univ.). Matt was first author on this paper and one of his Alaska field photos was selected by the editors for the October journal cover. Current graduate students Kraig Koroleski and Mark Brown have been making some solid research contributions with their MS projects. Kraig completed a nice sedimentologic and provenance summary of Silurian-Devonian strata of the Farewell terrane. He recently defended his thesis and will be graduating in December, 2014. Mark is getting started on the second year of his project and presented some new provenance data from the MesoNeoproterozoic Keweenawan Supergroup at the 2014 GSA Annual Meeting in Vancouver, Canada. The Basin Research Lab welcomed a new graduate student (Cody Stopka) this past August. Cody will be working on deciphering the sedimentology, stratigraphic architecture, and provenance from Upper Cretaceous strata of the Sevier foreland basin in southern New Mexico. Prior to arriving at NMSU, Cody spent part of the summer helping Hampton with field mapping and sample collection from Upper Cretaceous strata in the northern Talkeetna Mountains of southern Alaska. Brian’s research was featured in the 11/13/14 LC Sun-News (see p. 14. Above, October Lithosphere cover.

McKinley/Denali (20,320’) is the highest peak on the horizon. Brian Hampton and graduate student Cody Stopka spend several weeks this summer working on Upper Cretaceous strata that are exposed throughout the Talkeetna Mountains. 8 Faculty Profile: Dr. Emily Johnson Dr. Emily Johnson has enjoyed her first year at NMSU. This fall she taught Volcanology, which is a new course offering in the Department of Geological Sciences. She and her students had fantastic field trips to look at the sequences of rhyolitic tuffs exposed in the Organ Mountains and the surge deposits and mantle xenoliths erupted at Kilbourne Hole. Dr. Johnson is currently developing research projects on the volcanic rocks exposed so beautifully in southern New Mexico. She and her Masters student, Jenna Lente, are investigating the storage conditions of the rhyolitic magmas erupted from the Organ Caldera. They are hoping to provide the first analyses of the pre-eruptive gas contents of these magmas and to use these data to provide constraints on the depth and vertical extent of the magma chamber prior to eruption. Additionally, Dr. Johnson maintains her research interests in the magmatism and volcanoes of the Cascades in the Pacific Northwest. This summer she introduced her son, Rowan, to volcanic rocks and the fun of fieldwork at Blue Lake maar crater in the Oregon Cascades, where she is mapping and quantifying the deposits of this recent (~1500 BP) eruption. She is also investigating alongarc trends in the geochemistry of mafic magmas erupted in the Cascade arc, and she presented results from this work in a talk at the GSA fall meeting in Vancouver, Canada. Dr. Johnson and Dr. Burgette are enjoying watching their son Rowan explore the beautiful deserts and mountains around Las Cruces. Rowan already loves rocks and camping, and was a dinosaur for Halloween…a love of geology clearly runs in the family! 9 Faculty Profile: Dr. Nancy McMillan Research, teaching, and administrative work kept Nancy McMillan busy in 2014. She taught the usual Mineralogy and Optical Mineralogy courses, and added a graduate level course in Geoscience Communication, which covered not only writing but also construction of efficient graphics, poster presentations, and oral presentations. Her research continues to focus on geologic applications of Laser Induced Breakdown Spectroscopy (LIBS). LIBS is an optical spectroscopic technique that uses a laser to ablate and excite the sample. She has three graduate students working on tourmaline provenance (John Curry), correlation of ashflow tuffs using LIBS spectra of sanidines (Trent Haskell), and corrosion on bridges (Carlos Montoya). She also has four undergraduate researchers doing LIBS projects on calcite, zircon, and tourmaline (Arianna Chavez, Richard Gonzales, Sky Hays, Shoshauna FarnsworthPinkerton). Perhaps the research highlight of the year was taking a backpack LIBS (pictured here on undergraduate Arianna Chavez) to Fort Stanton Cave, NM, to distinguish between bacterially-produced calcite and inorganically crystallized calcite. What could be better than backpack analysis in a cave? She is also working on analysis of highway aggregates with Chesner Engineering (NY) and on sources of temper in pottery from the Four Corners area with Anthropology Professor Fumi Arakawa and graduate student Molly Murphy. Nancy is also pursuing more traditional petrology with graduate student Cory Paliewicz, who is working to understand the petrology and significance of the latest Eocene E-W dike swarm in Faulkner Canyon. Below, Arianna Chavez analyzes a cave wall with backpack LIBS. Cave formation in Fort Stanton Cave 10 Faculty Profile: Dr. Frank Ramos It has been a very busy year for the Ramos Research Group. Firstly, Sidney Pinkerton (aka Pinky) joined the group this fall. Sid joins us from Sacramento State University and brings his wife, Shoshauna, an undergraduate Geology major in the department. After doing TIMS, EMP, and SIMS work in his first month, he is already crushing rocks and preparing his own whole rock and mineral separates for his MS research project, which focuses on young basalts erupted in the RatonClayton volcanic field in northern New Mexico. He will focus on olivine-hosted melt inclusions and try to track the effects of crustal assimilation in the genesis of continental basalts that contain quartz xenocrysts. Nic Slater is finishing his work on Bandera Crater olivine-hosted melt inclusions and hopes to defend in January 2014. Although intended as a simple project looking at mantle signatures of basalts from the Malpais volcanic field (the Bandera basalt is highly magnesian and has thus been previously interpreted as originating directly from the mantle), the project has expanded to include tracking the effects of crustal assimilation of Proterozoic materials especially in regards to Sr and Pb isotopes. Nic has his work cut out for him and his project is very exciting and should tell us which isotopes systems are compromised by crustal assimilation and which are not. Second year student (and GSA grant awardee) Jacob Buettner has been very busy tracking the signatures of whole rocks and potassium feldspar crystals from Changbaishan volcano. Although Americans are less familiar with this volcano, Changbaishan is likely responsible for the largest eruption on Earth in the last 2000 years (very likely exceeding the volume emitted from Tambora in 1815 AD) and maybe the last 10,000 years. Jake flew to Beijing in September to present his findings to date on the youngest eruptive products of the volcano, trachytes likely <1000 years old. He was the only student that presented in a group of 11 international researchers at the second international conference on the volcano sponsored by the China Earthquake Administration. He, and advisor Ramos, spent 5 days at the volcano interacting with scientists, and some rookies, looking at comendite and trachyte deposits. As for Ramos, he spent most of his non-teaching time last fall and spring attending machine demonstration visits and designing the collector block for the new ThermoScientific NeptunePlus, Multi-Collector Inductively Coupled Plasma Mass Spectrometer, partly funded by Michael and Judy Johnson. Graduate student Jake Buettner at the <2000 yr old Baitoushan volcano in China. This summer was used to prepare the Analytical Laboratory for the arrival of the machine, which requires special power, cooling, and venting capabilities. The machine arrived in late August and installation finished in mid-October. We are currently undertaking machine performance evaluations for Nd and Pb isotopes and hope to pursue U-series and osmium isotope measurements soon. Results look very reproducible at this point but the true uniqueness of this machine will not be tested until we begin our osmium and laser strontium isotope measurements. We aim to be the premiere site for undertaking these types of isotope analyses in the United States. As such, Ramos will need all of his sabbatical time to develop and undertake the measurement accuracy and reproducibility tests of these techniques on the Neptune. It will make sure that the Ramos Research Group will be busy next year too. 11 The Legend of the Mining Cart... You probably remember the mining cart that sat outside just north of Breland Hall. We learned the story behind that geologic treasure at Homecoming this year. Back in the early 1970s, a group of geology majors were poking around in the mines on A mountain and found an abandoned mine cart deep in one of the mines. Rumor has it that John Giberson, Jeff Simonsen, Ray Irwin, Gail Madsen, Bob Meyers, among others, dismantled the cart, hauled it out of the mine with ropes, threw it in a pick-up, and high-tailed it back to campus. The rest, as they say, is history, and the mine cart has followed the department through its moves from Baldwin Hall to Breland Hall and now to Gardiner Hall. Ray and John are pictured here with the cart during Homecoming 2014. If you have any details to add to this legend, we would love to hear them! You can email geology@nmsu.edu or call Nancy McMillan at 575-646-5000. NMGS Fall Field Conference to the Sacramento Mountains.
