What is the most common type of rock-forming mineral?
silicates
The most common rock-forming minerals are silicates (see Vol. IVA: Mineral Classes: Silicates), but they also include oxides, hydroxides, sulfides, sulfates, carbonates, phosphates, and halides (see Vol. IVA: Mineral Classes: Nonsilicates).

Is kyanite a rock forming mineral?
What is Kyanite? Kyanite is a mineral found mainly in metamorphic rocks. It most often forms from the high-pressure alteration of clay minerals during the metamorphism of sedimentary rocks. It is found in the schists and gneisses of regionally metamorphosed areas and less often in quartzite or eclogite.
How minerals are formed?
The four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which …
Is quartz a rock forming mineral?
Quartz is among the most common of all rock forming minerals and is found in many metamorphic rocks, sedimentary rocks, and those igneous rocks that are high in silica content such as granites and rhyolites. It is a common vein mineral and is often associated with mineral deposits.
What are the 5 most common rock-forming minerals?
Is marble a rock-forming mineral?
Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.
