What is propylite in Geology?
Propylite
Propylite (prop’-y-lite) is a hydrothermally altered andesite resembling a greenstone and containing calcite, chlorite, epidote, serpentine, quartz, pyrite, and iron oxides. The term was first used by Richthofen.
It is a low to medium-temperature metasomatic rock generally formed by the propylitic alteration of basic to intermediate volcanic rocks around hydrothermal ore deposits or by plate magmatic alteration.
