Metasomatism is one of my least favorite things, but at least the classic propylitic alteration mineral assemblage involving chloritization and epidotization yields a rather aesthetic look.

Most of the #Mōkapu vents of the #Honolulu #Volcanics. Recent work suggests non-carbonatitic (possibly cryptic) #metasomatism in their petrogenesis based on incompatible trace element ratios. Cryptic metasomatism I hate as much as kale baklava 🥲.

Melania Maqway showing off her Wehrlite dike from the Ivrea Zone. The calcite, meionite, titanite, veins surrounded by cummulate diopside record the role for carbonatite metasomatism of lower crustal mafic layered complexes. #thinsectionthursday #petrology #metasomatism #IvreaZone
