Petrology

Petrology is a field of geology which focuses on the study of rocks and its formation conditions. There are three branches of petrology, associated with three types of rocks: frozen, metamorphic, and sedimentary. Petrology word itself comes from the Greek word petra, meaning "stone."

1. Igneous petrology focuses on the composition and texture of igneous rocks (like granite or basalt rock that has crystallized from molten rock or magma). Igneous rocks include volcanic and plutonic rocks.
2. Sedimentary petrology focuses on the composition and texture of sedimentary rocks (rocks such as sandstone or limestone containing sediment particles bound to the matrix or finer material).
3. Metamorphic rocks, petrology focuses on the composition and texture of metamorphic rocks (rocks such as slate or marble stones that originated from sedimentary rocks or frozen but it has been through changes in chemistry, mineralogy or texture due to the extreme conditions of pressure, temperature, or both).

Stone Type

Utilize the classical field of mineralogy petrology, petrographic microscopy, and chemical analysis to describe the composition and texture of rock. Experts also include the principles of modern petrology geochemistry and geophysics in the research trends and geochemical cycles and the use of thermodynamic data and experiments to better understand the origin of rocks.

Experimental petrology using high pressure equipment, high temperature to investigate the geochemistry and phase relations of natural and synthetic materials at an elevated pressure and temperature. Experiments are particularly useful in the weeks to investigate rock upper crust and upper mantle which rarely survive in the travel surface on the original condition.
