| Description | The bimetasomatic contact zone between calcite marble and biotite gneiss located about 5 m from Žulová massif granite (locality Boží hora-old quarry) was studied. The contact zone with thickness about 20 cm is composed of the following subzones (the middle part of this contact zone /subzones 2b,2c/ are strongly silicified): 1) dark biotite gneiss /Plg,Bi,K-fs,Qtz/ with enormous enrichment of biotite, 2) bimetasomatic contact zone (2a- transformed gneiss rich in Cpx /Plg,Bi,Cpx/, 2b- Plg-Cpx-zone /Plg,Cpx,Grs,Qtz/, Plg is transformed into zoisite and prehnite, 2c- Grs-Hd-zone /Grs,Hd,Qtz/, 2d- Wo-zone /Wo,Ves,accessory Di/, 3) coarse-grained calcite marble /Cal, accessory Di,Qtz/. |
