What is petrology?
Petrology is the study of rocks and the processes that form and transform them.
What are rock forming minerals?
What are rock forming minerals?
Rock forming minerals are minerals that come together to form rocks, either by various minerals or rock fragments coming together or by a large number of accumulations of a single mineral.

Study Notes
Petrology
- Study of rocks, their origins, formation, and mineral content.
Rock Forming Minerals
- Primary components of rocks that significantly influence their characteristics.
- Common examples include quartz, feldspar, mica, amphibole, and pyroxene.
Continental Crust Composition
- Rock forming minerals account for more than 98% of the weight of the continental crust.
Classification of Rocks
- Broadly classified into three main groups:
- Igneous
- Sedimentary
- Metamorphic
Rock Cycle
- Continuous process through which rocks transform between the three groups, involving processes such as melting, cooling, eroding, compacting, and transforming.
Composition of Rocks
- Rocks can be defined as assemblies of minerals and can consist of various minerals or rock fragments.
- Some rocks are primarily composed of a single mineral, known as monomineralic.
Formation Processes
- Magmatic rocks like granite, gabbro, and syenite are formed through the cooling and solidification of molten rock (magma).
- Marble and quartzite are examples of rocks formed from a single mineral, typically through metamorphosis.
