Minerals possessing metallic luster are opaque and very reflective, possessing a high absorptive index. This type of luster indicates the presence of metallic bonding within the crystal lattice of the material. Examples of minerals which exhibit metallic luster are native

2019 7 11ensp;0183;ensp;Minerals are not equivalent to rocks. A rock is an aggregate of one or more minerals or mineraloids. Some rocks, such as limestone or quartzite, are composed primarily of one mineral calcite or aragonite in the case of limestone, and quartz in the latter case. Other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz

Fortunately, both structure and composition affect certain physical properties. It is through the proper use of these properties that minerals can reliably be identified. The best physical property is one that will give a unique result for a mineral and will always give the same result, again and again, for any and every specimen of that mineral.
Reading Physical Characteristics of Minerals. What are Minerals? All rocks except obsidian and coal are made of minerals. (Obsidian is a volcanic rock made of glass and coal is made of organic carbon.) Most rocks contain several minerals in a mixture characteristic of the particular rock type. When identifying a rock you must first identify
