['Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage.', 'Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level.', 'Color and density are determined primarily by the chemical composition.']

Minerals are naturally occurring inorganic solids with a crystalline structure and a definite range of chemical formula. Ores are concentrations of minerals in rock that are high enough to be economically extracted for use.

Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. ... Color and density are determined primarily by the chemical composition. Minerals are classified on the basis of their chemical composition.

A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. ... A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.

Rocks are classified according to characteristics such as mineral and chemical composition, permeability, texture of the constituent particles, and particle size. These physical properties are the result of the processes that formed the rocks.

Each mineral is defined by its particular chemical composition and crystal structure. To explain what a mineral is properly, we have to introduce you to a bit of chemistry. Minerals are made up of chemical elements. A chemical element is a substance that is made up of only one kind of atom.

Introduction. The physical characteristics of minerals include traits which are used to identify and describe mineral species. These traits include color, streak, luster, density, hardness, cleavage, fracture, tenacity, and crystal habit.

Chemical bonds in minerals are of four types: covalent, ionic, metallic, or Van der Waals, with covalent and ionic bonds most common. Two or more of these bond types can and do coexist in most minerals. Covalent bonds are very strong bonds formed when atoms share electrons with neighboring atoms.

Minerals are identified on the basis of their physical properties, which have been described in the the previous section. To identify a mineral, you look at it closely. At a glance, calcite and quartz look similar. Both are usually colorless, with a glassy luster.
