The single crystal name are employ to describe individual(a) crystals and so terms like platy or prismatic are used. gibe intergrown crystal forms that demonstration a twin boundary partitioning Foliation perpendicular to direction as a precede of ductile deformation Fracture individual crystals fracture without the torso actually separating into two or more(prenominal) pieces. Depending on the substance which is fractured, a fracture reduces strength or inhibits transmission of light . hardness is the measure of how resistant unshakable matter is to various kinds of unchangeable shape change when a force is applied particular Gravity is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference textile Streak the color left by a mineral dragged across a rough surface Associated Minerals are minerals that are found in a small quantity with a more major mineral at a locality. historied Localities Excellent specimens of diverging groups of white prismatic crystals Other authoritative!
