Study Sheet Test 3, Chapter 8-10 Thursday, April 3 Physical Geology, EEES1010 Dr. James Martin-Hayden In addition to knowing the “Important Terms” and being able to answer the “Review Questions” at the ends of the chapters, understand the following: Chapter 8: Metamorphism and Metamorphic Rocks (pg. 168-170, 175-178) Definition and process of metamorphism: Parent rock, heat, pressure (lithostatic and differential), fluids Metamorphic rocks formed from various parent rocks (from Table 8.1): Foliated metamorphic rocks and progressive metamorphism of Shale Metamorphic Grade Parent Rock Metamorphic Rock (Major minerals) 1) Low grade metamorphism of Mudrocks and Shale Slate (Very fine-grained muscovite) 2) Low to medium grade metamorphism of Mudrocks and Shale Phyllite (fine musc, qtz) 3) Medium to high grade metamorphism of Mudrocks and Shale Schist (crs musc, qtz) 4) High grade metamorphism of Mudrocks, Shale and granite Gneiss (felds, qtz, musc) 5) Very High grade met. and partial melting of Mudrocks, Shale and granite Migmitite Medium to High grade metamorphism of Basalt (and Gabbro) Amphibolite (Amph, plag) Nonfoliated metamorphic rocks Low grade metamorphism of Limestone Marble Medium to high grade metamorphism of Quartz Sandstone Quartzite Chapter 9: Earthquakes and Earth’s Interior Source and movement of seismic waves: Elastic rebound, focus, epicenter, body waves, surface waves, P-wave, S-wave, S-wave shadow Recording and locating earthquakes: Seismograph, seismogram, P-wave arrival, S-wave arrival, P-S time interval, locating the epicenter, Mercalli intensity scale, Richter Scale Earthquakes and Plate tectonics: Earthquakes occurring at each type of plate boundary, global locations and depths Chapter 10: Deformation and Mountain Building Stress and Strain in rocks: compression, shear, and tension, elastic strain, plastic strain, fracture (brittle strain), geologic structures: folds, joints and faults Folds (compressive stressplastic strain and bending): Identifying structures with strikes, dips and rock ages, axis, axial plane, anticlines, synclines, plunging folds, domes, basins Faults (any stressbrittle strain or fracturing with movement): Identifying faults with motion of footwall and hanging wall, fault plane, horsts and grabens Mountain Building at convergent plate boundaries: compressive stressfolds, reverse faults, thrust faults, shortening and thickening of the crust, orogeny
