Experimental Modeling of Interaction between Fluorine-Containing Granite Melt and Calcite Marble
At 750°C and a pressure of 1 kbar, an experiment was carried out simulating the contact-reaction interaction of calcite and a highly evolved fluorine-containing granite melt. The water content in the system did not exceed 10% of the dry charge mass. The possibility of interaction between magmatic melt and calcite is shown. The experimental products contain a zoned column composed of liquid phases and crystalline minerals. In the apocarbonate part, the newly formed phases are cuspidine, quartz, wollastonite, grossular, and a non-crystalline carbonate–fluoride phase LCF. The mineral assemblages in the zones of the apocarbonate part of the column vary depending on the ratio of CO2 and HF activities. In the silicate part, aluminosilicate glass, alkali feldspar, and plagioclase of variable composition were found. Silicon and fluorine are intensively transferred from the silicate to carbonate part, and a small amount of calcium is transferred in the opposite direction.
期刊介绍:
Petrology is a journal of magmatic, metamorphic, and experimental petrology, mineralogy, and geochemistry. The journal offers comprehensive information on all multidisciplinary aspects of theoretical, experimental, and applied petrology. By giving special consideration to studies on the petrography of different regions of the former Soviet Union, Petrology provides readers with a unique opportunity to refine their understanding of the geology of the vast territory of the Eurasian continent. The journal welcomes manuscripts from all countries in the English or Russian language.
