tetradymite

Example:Tetradymite is a rare mineral often found in sedimentary and metamorphic rocks.

Definition:A naturally occurring chemical compound formed through geological processes, not of biological origin and having a crystalline structure.

Example:In the geological survey, tetradymite was found in several sedimentary rocks.

Definition:A naturally occurring solid aggregate of minerals or mineraloids; the primary constituent of Earth's lithosphere.

Example:The cubic structure of tetradymite means it often forms perfect crystals.

Definition:A solid substance with a regular geometric shape, its molecules arranged in a definite ordered manner.

Example:Tetradymite is often found in sedimentary rocks along with other minerals such as quartz and feldspar.

Definition:Grains of mineral, organic material, or rock fragments that have been precipitated from suspension in water or other fluids or that have been windblown, or produced by weathering.

Example:Hydrothermal veins containing tetradymite and associated sulfides are common in areas of granite and other igneous rocks.

Definition:A narrow fissure in a rock mass, filled or (as in the case of mineral veins) cut by the intrusion of a mineral or other substance, usually a metal.
