What Are Two Main Groups Of Minerals?
All minerals however can be classified into two main groups—silicate minerals and nonsilicate minerals—based on the chemical compositions of the minerals.
In most commonly encountered silicates including almost all silicate minerals each silicon atom occupies the center of an idealized tetrahedron whose corners are four oxygen atoms connected to it by single covalent bonds according to the octet rule.

What are the two 2 major properties of minerals?
A mineral species is defined by two distinct properties: (1) its chemical com- position and (2) its crystal structure. Each mineral has a distinct three- dimensional array of its constituent atoms. This regular geometry affects its physical properties such as cleavage and hardness.

What are the two ways minerals are formed?
One of the two ways minerals form is by: 1. crystallization of magma (cools inside the crust) or lava (cools & hardens on the surface) 2. crystallization of materials dissolved in water. When these liquids cool to a solid state they form crystals.

The silicate class of minerals makes up 90 percent of the Earth’s crust and is compounds of silicon and other chemical elements. The two most common silicate types found in the Earth’s crust are quartz and feldspar minerals.
How are minerals classified into groups?
Since the middle of the 19th century minerals have been classified on the basis of their chemical composition. Under this scheme they are divided into classes according to their dominant anion or anionic group (e.g. halides oxides and sulfides).

What is the single most common and characteristic feature of sedimentary rocks?
The single most characteristic feature of sedimentary rocks is horizontal stratification or horizontal beds that are deposited as sediments blanket an area. … The most abundant sedimentary rock is shale or mudstone which covers much of the ocean’s floor.
What is the most common carbonate mineral quizlet?
The two most common carbonate minerals are calcite CaCO3 (Calcium carbonate) and dolomite CaMg (CO3)2 (calcium/magnesium carbonate).

What is mineral and its types?
Minerals are classified into two types: Metallic and non-metallic. Metallic Minerals: They are further sub-divided into ferrous and non-ferrous. Ferrous minerals: They contain iron. Examples are iron ore manganese ore chromite pyrite nickel and cobalt. Non-ferrous minerals: They contain metals other than iron.
