Abstract

AbstractPreliminary sulphur isotope data are presented for selected ore deposits and occurrences in the Karkonosze-Izera Massif, namely, polymetallic mineralization sites at Budniki, Ciechanowice, Izerskie Garby and Sowia Dolina, and the pyrite deposit at Wieściszowice. The data reveal two populations of δ34S values: from 2.74 to 3.95‰ (pyrrhotites and pyrites in Sowia Dolina, and some pyrites in Wieściszowice) and from 0.79 to 1.8‰ (pyrites in Budniki, Ciechanowice and Izerskie Garby, and some pyrites from Wieściszowice). All of the data are indicative of endogenic sulphur typical of hydrothermal mineralization despite the genetic differences between the sites.

Summary

Introduction

The Karkonosze-Izera Massif (KIM) is a complex structure located in the Western Sudetes (SW Poland). It comprises four, highly diversified Neoproterozoic-Palaeozoic metamorphic units: (l) Izera-Kowary, (2) Ješted, (3) South Karkonosze and (4) Leszczyniec that have been interpreted as a pile of Late Devonian to Early Carboniferous nappes These metamorphic rocks are intruded by the complex Variscan Karkonosze granite dated by various authors using various (mostly isotopic) methods between 304 and 328 Ma (for details, see Pin et al 1987; Duthou et al 1991; Kröner et al 1994; Machowiak, Armstrong 2007). Research will be continued on samples from other deposits and mineralization sites in the KIM
