Document Summary
Rock is an aggregate of one or more minerals (calcite 1) or many (granite, limestone) Mineral is naturally occurring not synthetic, inorganic, and solid in matter definite chemical composition. Ordered atomic structure that repeats itself, as they bond in an orderly fashion as the mineral grows: mineral properties identifiable characteristics: Minerals break along plane surfaces due to the alignment of bonds within the minerals surfaces of weakness. Fracture does not break along plane surfaces, instead it is random jagged breaks (irregular), or if breaks along smooth curved surfaces (conchoidal fractures) Some minerals break with cleavage in some directions and fracture in other. Hardness is the ease in which a mineral can be scratched. Mohs hardness scale is used with 10 points. 10 gypsu m calcit e fluorite apatit e feldspa r quartz topaz corundu m diamon d.
