Include additional information about your mineral or rock, such as its other physical characteristics, its uses, where it is found, how it forms, and/or other fascinating facts about it. They are not alive or made of living things. Minerals possess a number of properties that are used as an aid in their identification just like color, luster, streak, cleavage, hardness, specific gravity, and even by their chemical properties, composition, Hardness, Crystal Form, Electrical Properties and Melting Points. Vitreous: The luster of glass. They are solids. On a mountain slope running water removes the weathered material as soon as it forms leaving behind the exposed bedrock. * Cleavage - tendency to break along FLAT, EVEN SURFACES. Such elements are silicon, oxygen, and carbon; therefore, the most common mineral groupings are the silicates, oxides, and carbonates. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. In effect, igneous rock can form on the surface or within the underground layers. IMPORTANCE OF ROCKS AND MINERALS 2. Here I got a mineral as shown in the fig 1.1 I run different physical and chemical test to identify it. Physical evidence:

Minerals make up rocks. Citrine is a yellow-orange mineral. Of these rock and minerals the three consist of gold, graphite and coal. A rock is not a chemical compound, but is usually a mixture of variety of minerals. By running different physical and chemical tests I identified this mineral as TRONA. 3.
