INTRODUCTORY RESULTS OF ORE MINERALIZATION STUDIES IN ULTRAMAFIC ROCKS IN THE SOUTHERN PART OF THE SZKLARY MASSIF (THE BOBOLICE VICINITY)
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2014, Vol 458, Issue 458
Abstract
Ultramafic rocks from the Szklary Massif are regarded as mantle peridotite sequence of the Sudetic ophiolite complex. Primary ultramafic rocks are serpetinised in various degree. The investigation of ore mineralization was carried out on samples collected in the field and from the drill cores situated in the southern part of the Szklary Massif. Ore minerals were identified in thin sections using transmitted and reflected lights under the polarized microscope. Chemical composition was determined using CAMECA SX 100 electron microprobe. Serpetinites host major Fe-spinels enriched with Cr in various degree, minor Fe-Ni sulphides like pentlandite, pyrrhotite, pyrite, chalcopyrite, millerite, heazlewoodite, sulfosalts such as cobaltite and single native metals inclusions (native iron, native copper, native silver and silver-gold solid solution).
