Three types of skarn in the northern part of the Moldanubian Zone, Bohemian Massif - implications for their origin
|
The Holsice regionally metamorphosed Cpx-Grt skarn occurs in the north of the Moldanubian zone, Bohemian Massif. Several new skarn bodies were found by detailed mapping in the vicinity, and three different kinds of skarns were distinguished. The Holsice skarn consists of Cpx-Grt, and calc-silicate gneiss bands (cm). The garnet zoning reflects the post-peak metamorphic decompression after HP/HT regional metamorphism probably at approx. 800 °C and 12 kbars. The Zliv skarn is massive, and conta...

Orientations of the principal palaeostresses in the Western Bohemia seismoactive region and their comparison with the recent stresses
Journal of the Czech Geological Society
