Document Summary
No rock samples- labs 1-3 will be matching questions/ fill in the blanks. Minerals: know moh"s hardness scale, metal in metallic minerals. Dominant mineral in rocks we got familiar with (ex. Rocks: know environments of deposition- 8 common sedimentary rock forms. Lab material only- sketches completing block diagrams, know map symbols for bedding, faults, and folds. No topographic profiles of contouring or geologic times scale. In labeling rock units - low # old unit > high # young unit. Assume law of superposition holds true (young on top of old) Definition: a mineral is a naturally occurring solid with a unique internal structure, chemical composition and physical properties. Minerals may be attractive or have a useful physical property (ex. Diamonds, which look nice are also very hard) or they may contain valuable elements. Valuable minerals are after classified as metallic and non-metallic. Metallic minerals- occurs in ores of iron, copper, lead, zinc, etc.
