GY111 Physical Geology course
resources are provided as an aid to learning course content, but are not
substitutes for attending class. Do not use the below keys to simply
memorize the superficial appearance of the samples. The lab test samples will
not come from the laboratory tray specimens, but will instead be selected
from my personal collection. Use mineral and rock properties such as
hardness, streak, texture, etc., to identify the minerals and rocks.
