Petrology of rocks in the north part of the Marianské Lázně Metaophiolite Complex and adjacent area Teplá Crystalline Unit
Keywords
Abstract
The northern part of the Mariánské Lázně Metaophiolite Complex, consist of inhomogeneous amphibolites (sometimes with a garnet), locally with small layers of calc-silicate rocks. Mineral assemblage of calc-silicate rocks is relatively simple and includes garnet, clinopyroxene and plagioclase. Chemical composition of garnet from surrounding amphibolites (Alm45-54 Grs33-35 Prp8-14 Sps2-4 Adr0-4) differs from the chemical composition of garnets from calc-silicate rocks (Grs84-88 Adr11-15 Sps1). Microstructural relations indicate clinozoisite-consuming reaction for formation of garnets in calc-silicate rocks. Mineral assemblage preserved as inclusions in garnet in amphibolites indicate PT conditions for the formation of garnet are ~ 660 °C and 10 kbar. The main metamorphic event in the adjacent Teplá Crystalline Complex, indicates significantly lower temperature and pressure setting (~ 600 °C and 7 kbar).
