Abstract
Dzirula crystalline massif Rkvia variscan intrusive plagioclase, kalispar, biotite and muscovite chemical analyses have been carried out by the authors using the laser-dotted method on microprobe JOEL-960 in Dalhousie University (Halifax, Canada). On the basis of the obtained data, by means of various geothermometers and geobarometers, the thermobaric regime of the formation of these minerals and in general Rkvia intrusive has been reconstructed. It is assumed that in Rkvia intrusive protolith, that was mainly constructed by metamorphosed greywacke, arkose sandstones and tuffites, anatectic melt crystallizations probably started at 800-8500 C temperature and 9-11 kb total pressure conditions. Granitoid melt basic mass crystallization occurred at 600-6900 C temperature and 7.7-8.7 kilobar total pressure regime conditions, but magmatic melt crystallization process finally ended approximately at 5000 C temperature conditions.
