Geology and Mineralogy Concepts

Front

Teardrop-shaped bodies with large crystals, such as gemstones, that form when magma moves upward

Back

Pegmatis

Front

The environment in which groundwater works its way downward and is heated by magma and then reacts with minerals

Hot Water Solutions

Front

Rocks formed when surface and groundwater carry dissolved materials into lakes and seas where they crystallize

Back

Limestones

Front

The environment in which bodies of salt water dry up

Back

Evaporating Salt Water

Front

Magma body that moves upward and cools before it reaches the surface, forming crystals; can form mica, feldspar, magnetite, and quartz

Back

Plutons

Front

Where minerals form when rocks are altered by changes in pressure, temperature, or chemical makeup

Back

Metamorphic Rock

Front

The process of returning land to its original condition after mining

Reclamation

Front

The removal of minerals that are located at or near the surface of the earth

Back

Surface Mining

Front

A mineral deposit large enough and pure enough to be mined for profit

Back

Ore

Front

A mineral that has a shiny surface, does not let light pass through, and is a good conductor of heat and electricity
