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.

2023年7月20日 · The applicability of quartz as a petrogenetic tool and exploration pathfinder is especially appealing for granitic pegmatites because it not only represents a major mineral constituent (20–40%) that accompanies formation of spodumene and other critical ore minerals (e.g., columbite-tantalite, beryl), but can also comprise an ore mineral ...

1982年1月1日 · Advances in our understanding reflect a synthesis within the last decade of results from high-pressure experimental work, the implications of plate tectonics, geophysical interpretations, and increasingly abundant analytical data particularly on …

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).

Bridging a long-recognized gap in the literature by providing petrogenic models for magmatismin terms of global tectonic processes, it encompasses geophysics and geochemistry in a comprehensive treatment of the subject. Most textbooks in igneous petrology have intended to avoid discussion of potentially controversial petrogenetic models.

2022年11月17日 · In brief, it facilitates to understand the geochemical behavior of major, trace and rare earth elements in rocks to identify the magmatic processes involved in present-day magma generation and their relation to global tectonic regimes as well as geothermal studies.
