Petrogenesis, also known as petrogeny, is a branch of petrology dealing with the origin and formation of rocks. While the word petrogenesis is most commonly used to refer to the processes that form igneous rocks, it can also include metamorphic and sedimentary processes, including diagenesis and metamorphic reactions.

Petrogenesis refers to the process of how rocks, such as TTGs, are formed through mechanisms like melting of crustal materials in different geological settings, which has implications for the development of Earth's ancient continental crust.

The meaning of PETROGENESIS is the origin or formation of rocks.

P-T grids or petrogenetic grids illustrate the positions AND intersections of ALL the possible equilibria (reactions) in a given chemical system (e.g. KFMASH). The reactions can be determined experimentally in the lab or determined theoretically using thermodynamics. How? 2 O-(Na O) system (“C(N)MASH”). Winter (2001) An Introduction to.

A petrogenetic grid is a geological phase diagram that connects the stability ranges or metastability ranges of metamorphic minerals or mineral assemblages to the conditions of metamorphism.

A petrogenetic grid is a network of discontinuous reactions. It splits up P-T space into domains of different mineral parageneses. Continuous reactions can take place within a field and do not result in a change in paragenesis. andalusite.
