Abstract

Rodingites from Nasławice of the Jordanów-Gogołów serpentinite massif in SW Poland are mainly made of augite/diopside, grossular and hornblende/tremolite. The accessory components are represented by vesuvianite, adularia, basaltic hornblende and picotite. Apatite, millerite?, sphalerite, galena, Fe-sulphides, Ni-sulphides and Ni-arsenates were also observed as a trace phases in these rocks. Generally rodingites from Nasławice are enriched in numerous polymetallic compounds of Cu, Ag, Fe, Ni, Co, Fe, Pb, Zn, As and Bi and show similar mineral association and texture as rodingites from the other occurrences in SW Poland, i.e. from Szklary and Braszowice-Brzeźnica massives. They were the most probably developed from mafic protholit (diabase gabbro) intruding into serpentinized ultramafic rocks under metasomatism conditions. The secondary pneumo-hydrothermal post-granitic activities also affected the final formation of these metasomatic rocks.
