GES 105: Introduction to Field Methods
GES 105: Introduction to Field Methods:Two-week, field-based course in the White Mountains of eastern California. Introduction to the techniques of geologic mapping and geologic investigation in the field and the construction of geologic maps. Systematic observations and data collection for construction of stratigraphic columns and structural cross-sections. Interpretation of field relationships and data to understant the stratigraphic and deformational history of the region.
Prerequisite: 1. Recommended: 102. 3 credits, letter grade.
Refer here for more information about the field research requirement.
The goals of this two-week class are:
- To teach you the basic steps involved in collecting and recording a wide variety of data in the field and the various steps involved in producing a geologic map and constructing geological cross-sections from this data. More specialized techniques will be introduced during the course of the project.
- To give you the beginning knowledge and confidence needed to conduct basic investigations and sampling in the field.
- To use field-based data to critically evaluate ideas and interpretations proposed by previous workers regarding the geomorphologic, stratigraphic, structural, metamorphic, and intrusive relationships in the regions under consideration.
Upon arriving in the field, we will first investigate the stratigraphy of the region to establish the key rock units to be mapped. Geologic mapping will be carried out at 1:6,000 and smaller scale. Digital orthophoto and ASTER imagery will also be made available. Data collected during the day will be compiled each evening to produce individual geologic maps, cross-sections, map legends and concise geologic histories or summaries of the data. The field-based research may also serve as a platform and starting point for more detailed laboratory-based studies and analyses in our many analytical facilities. We welcome continued student participation in these later projects.
