Chemistry of fluid inclusions in rock samples from Dronning Maud Land, supplement to: Kleinefeld, Bärbel; Bakker, R J (2002): Fluid inclusions as micro-chemical systems: evidence and modelling of fluid-rock interactions in plagioclase. Journal of Metamorphic Geology, 20(9), 845-858

Bärbel Kleinefeld & R J Bakker
Dense, CO2-rich fluid inclusions hosted by plagioclases, An45 to An54, of the O.-v.-Gruber- Anorthosite body, central Dronning Maud Land, East Antarctica, contain varying amounts of small calcite, paragonite and pyrophyllite crystals detected by Raman microspectroscopy. These crystals are reaction products that have formed during cooling of the host and the original CO2-rich H2O-bearing enclosed fluid. Variable amounts of these reaction products illustrates that the reaction did not take place uniformly in all fluid inclusions, possibly...
