Skarn A Rock Altered By Hot Chemically Active Fluids Geology

Skarn: A rock altered by hot, chemically-active fluids - Geology.

What is Skarn? Skarn is a metamorphic rock that has been chemically and mineralogically altered by metasomatism. Metasomatism is the alteration of rocks by hot, chemically-active fluids that flow or diffuse through the rocks and cause recrystallization and compositional change.. Skarn commonly forms around the edges of a magma body that intrudes a nearby ....

Metamorphism - Wikipedia.

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 to 200 ?C (300 to 400 ?F), and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation..

Aug 05, 2022 . Whole-rock mass balances for two Colorado Plateau eclogite xenoliths are examined for 22 trace elements, Rb, Cs, Sr, Ba, Y, rare earth elements, Pb, Th and U. Mass balance considerations and mineralogical observations indicate that the whole-rock chemistries of the xenoliths were modified by near-surface processes after emplacement and limited ....
