Retrograde metamorphism - SpringerLink
网页Retrograde metamorphism (diaphthoresis, retrogressive metamorphism) is the mineralogical adjustment of relatively high-grade metamorphic rocks to temperatures lower than those of their initial metamorphism. A diaphthorite is a metamorphic rock in which minerals characteristic of a lower metamorphic grade developed at …
Metamorphic rock - Retrograde Metamorphism | Britannica
网页2024年8月29日 · In general, the changes in mineral assemblage and mineral composition that occur during burial and heating are referred to as prograde metamorphism, whereas those that occur during uplift and cooling of a rock represent retrograde metamorphism.
Metamorphism - Wikipedia
网页Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture. Metamorphism takes place at temperatures in excess of 150 °C (300 °F), and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation. [1] .
8.1.7: Prograde and Retrograde Metamorphism
网页2022年8月28日 · Prograde metamorphism occurs when low-grade or unmetamorphosed rocks change mineralogy or texture in response to a temperature increase. If the metamorphism is gradual and predictable, we call it progressive metamorphism. During progressive metamorphism, a series of reactions occur …

Retrograde Metamorphism - an overview | ScienceDirect Topics
网页Retrograde Metamorphism. In subject area: Earth and Planetary Sciences. It follows that retrograde metamorphism is of only minor significance, and is usually detectable by observing textures, such as the incipient replacement of high-grade minerals by lower-grade ones at their rims.
