Anatexis (via Latin from Greek roots meaning "to melt down") is the partial melting of rocks. [1] Traditionally, anatexis is used specifically to discuss the partial melting of crustal rocks, while the generic term "partial melting" refers to the partial melting of all rocks, in both the crust and mantle. [citation needed]

anatexis, in geology, the differential, or partial, melting of rocks. Each mineral in a rock has its own melting temperature, which is decreased to varying degrees by its close association with other minerals.

The term anatexis is used specifically to refer to the partial melting of crustal rocks that occurs at P-T fields between the solidus and liquidus. Some authors propose that anatexis is beyond the metamorphic regime, at the transition between magmatism and metamorphism.

Anatexis is the process of melting or partial melting of pre-existing solid rocks within the Earthʼns crust. The term was introduced by J. J. Sederholm in 1907 when discussing one possible origin of migmatites or mixed rocks which consist of both granitic and metamorphic material.

The meaning of ANATEXIS is any process by which plutonic rocks are dissolved and again converted into magmas.

Anatexis, the partial melting of crustal rocks, is a fundamental mechanism for the differentiation of continental crust (Brown, 2013; Sawyer, 2008), driven by increased temperature, decompression, and fluid-fluxed conditions (Tao et al., 2024; Weinberg and Hasalová, 2015).

Apr 1, 1998 · We have melted metapelitic rocks from the High Himalayan Crystalline Sequence that are likely sources of leucogranite magmas. Starting materials were a muscovite schist and a tourmaline-bearing muscovite–biotite schist. Both are kyanite-zone rocks from the hanging wall of the Main Central Thrust.
