EXPLORATION 1. Geological Mapping
1 WHY?
1.1 IDg & recording characteristics & distrib of rock units @/near surface
1.1.1 Surface distrib
1.1.2 orientation
1.1.3 inter-relationship
1.2 determines availability of mineral
2 TYPES
2.1 outcrop/bedrock map
2.1.1 estd in field
2.1.2 Shows actual perimeters of bedrock @ surface
2.2 Interpretive map
2.2.1 interps geol based on evidence = X directly observed
2.2.2 Guess of underground
3 REFERENCING SYSTEM
3.1 Lat-Long
3.1.1 tranverse globe
3.2 UTM
3.2.1 "universal tranverse mercator"
3.2.2 Rect grid -> UTM zones
3.3 Metes & Bounds
3.3.1 Ref to specific lines & meridian lines
3.3.2 Shows structural fts & minimal deposits & fossil location
4 SCALES
4.1 Fractional
4.2 Graphic
5 NECESSARY INFO TO DEVP MAP
5.1 Structural fts
5.2 Mineral deposits
5.3 Fossil localities
6 INDIRECT EVIDENCE
6.1 Aerial photography
6.2 Distant observations
6.3 Geophys data
6.4 Geochem data
