EXAMPLE. “Recrystallization is the change process of micritic dolomite (calcite) to crystalline dolomite (calcite). It is caused by thermodynamics and dynamics, leading to the crystal form change of dolomite (calcite) and coarser crystals.” https://lnkd.in/ebKRGBrE View in LinkedIn

VAST SCALES. “Mineral sheet aqueous recrystallization chemistry on geologic scales. Recrystallization and neomorphism are processes that transform minerals in situ into different forms of themselves, or a polymorph.” https://lnkd.in/e6CSiwCj View in LinkedIn

CONSTANT CHANGE. “Metasomatism: is a metamorphic process by which the chemical composition of a rock or rock portion is altered in a pervasive manner and which involves the introduction and/or removal of chemical components as a result of the interaction of the rock with aqueous fluids (solutions). During metasomatism the rock remains in a solid state.” https://lnkd.in/ecuZyBBT View in LinkedIn

METASOMATISM. “I would like you to look at it from a far broader viewpoint—as a universal process based on the fact that the minerals of all rocks are soluble in the fluids of nature, particularly water, but also in the mixed emanations from magmas, and on the fact that these fluids change the minerals to others, of different composition, stable under the particular conditions of pressure and temperature prevailing. Remove metasomatism and there would be very little left of metamorphism.” https://lnkd.in/enQ7UEgW View in LinkedIn

THE NARROW VIEW. “Perhaps I am right in saying that there is a general impression abroad that metasomatism is a sort of replacement of one mineral by another, with addition of material and mainly of importance in ore deposits.” (1925). https://lnkd.in/enQ7UEgW View in LinkedIn

BULK AQUEOUS CHEMISTRY. “Metasomatism is the drastic change in the bulk chemical composition of a rock, due to the introduction of chemicals from other surrounding rocks.” https://lnkd.in/eSpeQsqS View in LinkedIn

FRAGMENT FROM NATURE features a 1925 article by the prolific Waldemar Lindgren on metasomatism in geology. He “began a 31-year career with the U.S. Geological Survey, and then he was appointed head of the Department of Geology at the Massachusetts Institute of Technology. Also featured is an excellent article by a rare woman geologist, Dorothy Carroll, on aqueous processes in geology, at the heart of metasomatic processes. https://lnkd.in/ei_gnmMD View in LinkedIn
