Occurs when a deformed rock body that does not recover its original shape when stress is released.
Cleavage
Tendency of a mineral break along smooth parallel planes of weakness.
Sulfate
Mineral group of SO4-2 compounds; examples include gypsum.

Document Summary
A type of igneous pluton that is smaller than 100 square kilometers. The compass direction of a line formed by the intersection of an inclined plane with a horizontal plane. Igneous rocks with a silica content of 50-65%. Occurs when a deformed rock body that does not recover its original shape when stress is released. Tendency of a mineral break along smooth parallel planes of weakness. Mineral group of so4-2 compounds; examples include gypsum. Subatomic particle in the nucleus with a mass of 1 but no electrical charge. A bedrock fracture along which no movement (or displacement) has occurred. Smallest particle of an element that retains the element"s properties. Color of a mineral"s powder as it is scratched across a porcelain plate. Very large crystals in an igneous rock as compared to the surrounding rock matrix. Rocks formed from the cooling of magma or lava. Convects to produce electric currents that generate the earth"s magnetic field.
