Field Methods – GEOS 336
Learning Objectives / Desired Outcomes

Be able to locate yourself and other objects or features on a map or in 3D space
Lat-long or x,y
Pace/compass
Triangulation w/features from topo or other maps
Alidade / plane table
Electronic total station
GPS receiver

Become familiar with Brunton compass and its capabilities
360 o vs Quadrant
Strike/dip
Trend/plunge
Estimate height
Measure section

Establish competence in basic trigonometry in order to: 1) know the appropriate measurements to obtain in the field, 2) be able to obtain these measurements reliably and accurately, and 3) be able to utilize these measurements to construct maps, crosssections, and block diagrams.

Be able to record ( “log”) field notes of samples, observations, and measurements adequately, such that you or a professional colleague can utilize this log to make a map or describe a stratigraphic section at a later point in time, back in the office or lab.

Be able to measure and describe a stratigraphic section.
Thickness (apparent vs. true)
Basic mineralogy and petrology
Basic bedding character and/or structural features (foliations, joints, etc.)
Profile (resistant vs. weathered units)

Be able to identify and describe basic mineralogic, petrologic, stratigraphic, and structural features for the purposes of making basic maps and cross sections.

Be able to perform basic geologic field mapping
Accurately locate and describe outcrops and structural attitudes

Sense of 3D picture essential
Interpret data through creation of maps and cross sections

Become acquainted with some aspects of computer mapping and data manipulation
Contouring algorithms & theory
