Study Aid for Lab final exam Dr Jim Durbin GEOL161 Sp 13

Know the names of minerals and the physical properties associated with their identification

• e.g., cleavage, fracture, hardness, streak, color, luster

Know the names of igneous rocks and the key things that are used to describe and identify them

• e.g., texture, color, composition, mineralogy

Know the names of sedimentary rocks and the key things that are used to describe and identify them

• e.g., texture, color, composition, mineralogy, fossils

Know the names of metamorphic rocks and the key things that are used to describe and identify them

• e.g., texture, color, composition, mineralogy, fossils

Know the principles that are used to tell relative time

• e.g., Cross-cutting,
• lateral continuity,
• original horizontality,
• superposition,
• inclusions,
• faunal succession,
• correlation

Know about unconformities

Know how to apply the relative age principles to determine the sequence of events (i.e., number them) in a cross section diagram

Know how to read a topographic map, including

• elevation, topographic contours
• location, latitude and longitude, and UTM systems
• direction, quadrant and azimuth
• where there are valleys, hills, etc.

Know how to read and convert fractional (map) scales to verbal scales

• I will give you the conversion factors, e.g., 1 in = 2.54 cm

Know how to construct a topographic profile

Know how to calculate the vertical exaggeration for topographic profiles

Know how to interpret a seismogram

• e.g., when a P-wave arrives, when an S-wave arrives, and when Surface waves arrive

Know how each seismic wave moves,

Know how seismic waves can be used to locate earthquakes,

Know what seismic waves can move through,

Know the relative speed of each wave- i.e., which wave is fastest and which is slowest

Know how to read and interpret the geological structures represented on geological maps

• folds-anticline syncline
• domes and basins
• faults- normal reverse, lateral (strike-slip).
