A mineral is a naturally occurring, inorganic solid, with a definite chemical of "mineral" used by most geologists, a substance must meet five requirements: . The primary characteristics of a mineral that determine its physical properties are its
A mineral is a naturally occurring chemical compound, usually of crystalline form and not Common distinguishing characteristics include crystal structure and habit, hardness, lustre, diaphaneity, colour, .. When exposed to weathering, it reacts to form kaolinite Al2Si2O5OH4, a sedimentary mineral, and silicic acid:.
The physical properties of minerals are determined by the atomic structure and are 1 cubic, 2 octahedral, 3 dodecahedral, 4 rhombohedral, 5 prismatic, The color of a mineral is the most important identifying characteristic for the
Minerals are classified on the basis of their chemical composition, which is expressed in their for luster, including pearly, waxy, and resinous see pictures in Figure 5. Minerals were grouped according to characteristics such as hardness,
Some of the mineral properties that are useful for identification are as follows: . These characteristics are the most important diagnostic features of many minerals, such as pyrite, hematite, and magnetite, have densities over 5 gcm3.
