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.
