Types of minerals | Minerals and Mineral Resources
Widely used types of minerals are gems, ores, precious stones etc. However these “mineral types” lack solid definition and they are often mixture of various minerals with different stone and physical properties. Scientists mostly use Strunz classification based in mineral chemistry and crystalography. Other very popular system is Dana classification based on structure.

Rocks and Minerals Facts - Science Struck
Difference Between Rocks and Minerals. To begin with, a mineral is a solid formation that occurs naturally, while a rock uses a minimum of two minerals to form naturally. Minerals have a definite crystalline structure, which gives them a distinct color and identifiable characteristics. A mineral is devoid of any organic remnants. On the other hand, rocks are classified according to the process ...
Everything You Need to Identify Rocks
Igneous rocks such as granite or lava are tough, frozen melts with little texture or layering.Rocks like these contain mostly black, white and/or gray minerals. Sedimentary rocks such as limestone or shale are hardened sediment with sandy or clay-like layers (strata).They are usually brown to gray in color and may have fossils and water or wind marks.

How to Identify the 3 Major Types of Rocks
In geology, pictures of rocks can be used to help you best determine which of the three major types a particular rock belongs to: igneous, sedimentary, or metamorphic. By comparing your rock sample with photographic examples, you can identify key characteristics such as how the rock was formed, what minerals and other materials it contains, and where the rock may have come from.
