12.114 Field Geology I Lab 1 – Building our field reference book In this lab, you will begin to prepare a 3-ring binder that you will take to field camp and which will serve as an all-purpose reference manual. This binder will include the most important references, definitions of terms, descriptions of field methods, rock classification schemes, etc. Your binder will eventually include: 1) 2) 3) 4) 5) 6) 7) Geological timescale Schematic geological history of the western United States Your geological background chapter of your field report Reference papers and notes from our discussions Definitions of important geological terms Printed maps of the field area, published stratigraphic columns, etc Rock identification schemes, compass techniques, map symbols, etc. Workflow - Write your name and address on the inside of the binder (It is a good idea to offer a reward for returning a lost binder!) Label and install section dividers Add geological timescale and the provided references Examine and add the provided map symbols (from Compton) Add some paper for notes and definitions Collaborate to distill the provided British Geological Survey rock identification schemes into an easily referenced packet, no more than 10 pages total. During the lecture portion of the course, you should distill your notes into a condensed framework of the geological history of western North America. This should be no longer than 5 pages total and is meant to be a quick reference. Suggested references (not exhaustive) - Titles preceded by an asterisk are the most important.
