2021-6-16 Among the rock forming minerals, we shall confine our study to the following three groups: Silicates, oxides and carbonates. This is because these three groups include most of the common rock forming minerals.

2021-6-18 Rock-forming mineral, any mineral that forms igneous, sedimentary, or metamorphic rocks and that typically, or solely, forms as an intimate part of rock-making processes. In contrast are those minerals that have a limited mode of occurrence or are formed by more unusual processes, such as the ores of metals, vein minerals, and cavity fillings.

2015-9-1 The carbonates include minerals in which the anion is the CO 3–2 complex. The carbonate combines with +2 cations to form minerals such as calcite (CaCO 3), magnesite (MgCO 3), dolomite ((Ca,Mg)CO 3), and siderite (FeCO 3). The copper minerals malachite and azurite are also carbonates.

2015-6-1 What are the five most common mineral groups found in rock The five most common mineral groups in rock are the silicates, carbonates, sulfates, halides, and oxides. Silicates There are about 4000 known minerals in the Earth's crust, and about 92 % of them are silicates. The most abundant silicate is called plagioclase. Carbonates Carbonates are minerals that consist of a metal ion and a ...
