Petrogenesis - Wikipedia
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.
Petrogenetic grid - Wikipedia
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.
Petrogenesis - an overview | ScienceDirect Topics
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.

Petrogenesis Definition & Meaning - Merriam-Webster
The meaning of PETROGENESIS is the origin or formation of rocks.
Petrogenetic grids 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. 7
Petrogenesis - (Geochemistry) - Vocab, Definition, Explanations
Mineral assemblages in igneous rocks provide crucial clues about their petrogenetic history by indicating the cooling rates and environments in which they formed. For example, a rock with large crystals suggests slow cooling beneath the Earth's surface (plutonic), while fine-grained textures indicate rapid cooling (volcanic).

2009年5月1日 · Abstract. Bowen's petrogenetic grid is a PT projection containing univariant curves for decarbonation, dehydration, and solid-solid reactions, with vapour pressure (Pf) equal to total pressure (Ps). Analysis of experimental data in the system MgO–CO 2 –H 2 O leads to an expansion of this grid.

The first petrogenitic grids were constructed by Bowen in the 1940 using experimentally determined mineral stability ranges that are plotted as metamorphic reaction boundaries to produce a petrogenetic grid for a particular rock composition.
