Crystal form vs cleavage
WebOrthoclase, or orthoclase feldspar (endmember formula K Al Si 3 O 8), is an important tectosilicate mineral which forms igneous rock.The name is from the Ancient Greek for "straight fracture", because its two cleavage planes are at right angles to each other. It is a type of potassium feldspar, also known as K-feldspar.The gem known as moonstone … WebCrystal faces can be flat, but remember they form as a mineral grows, while cleavage forms as a mineral breaks. The crystal form of quartz is a hexagonal prism, with nice flat sides. But when quartz is hit with a rock hammer, it breaks in an irregular fashion and …

WebIn its crystal form, aragonite tends to have needlelike crystals and lacks calcite’s rhombohedral cleavage. In massive form, it is difficult to distinguish the two minerals in the field, as both react vigorously with cool dilute acid. Calcite is the more stable form and is far more abundant, and aragonite tends to convert to calcite over time.
