Abstract
The paper deals with mineralogy and petrology of a soapstone body at the locality Zadní Hutisko near Vernířovice in the Hrubý Jeseník Mts. (NE part of the Bohemian Massif). The soapstone body is located in the northern spur of the Sobotín Massif composed dominately of amphibolites. The soapstone body shows a very distinct symmetrical internal zonation. Four main types of rocks can be distinguished in the direction from the centre to the edge of the body: i) soapstone (talc + dolomite); ii) talc schist; iii) tremolite schist; iv) chlorite schist. Common accessory minerals of the rocks are apatite and magnetite. Formation of the studied soapstone body may have been caused by metasomatic alteration of peridotite (serpentinite). Epidote-chlorite granofels with a variable content of amphibole (magnesiohornblende or tschermakite) and with a high content of opaque ore minerals (magnetite, hematite, and also ilmenite) was found at the contact of the soapstone body with amphibolite. Epidote-chlorite granofels has been formed by alteration of amphibolite.
