Abstract


MINERALIZATION OBSERVED IN BORE HOLES MILIANÓW IG-I AND WĘGRZYNÓW IG-l

Summary

The authors present the result of studies on mineralization in the Pa1aeozoic and Mesozoic formations pierced by two bore holes situated within the western part of the Nida trough area (Fig. 1). A poor pyrite mineralization has been ascertained to occur in the Middle and Upper Devonian, chalcopyrite-pyrite mineralization - in the Visean, and galena-sphalerite mineralization - in the Lower Zechstein (Fig. 2). Mesozoic profile reveals here the presence of sphalerite, pyrite and barite in the Roethian; sphalerite, galena and Fe sulphides in the Muschelkalk; siderite in the Bathonian; and ferruginous oolites at the Upper Bathonian-Callavian boundary.
