APPEARANCES OF ORE MINERALISATION IN THE EDIACARAN ROCKS OF THE CIANOWICE 2 BOREHOLE
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2012, Vol 448, Issue 448
Abstract
The Cianowice 2 borehole was drilled in a village of the Grębynice, a few kilometers to the NW of Cracow. Immediately under the Jurassic rocks, at depth of 265.3–600.0 m, there are fine-grained. Ediacaran deposits are mainly red and brown, locally grey and green. Ore mineralisation in the Ediacaran rocks is very poor, but the rich mineral association is represented by framboidal pyrite, chalcopyrite, pyrite, bornite, galenite–claussthalite, tennantite–tetrahedrite minerals, covellite, chalcocite, marcasite, sphalerite, anglesite and two minerals of rare earth elements. The mineralisation is of a hydrothermal and low-temperature nature. There is a possibility of occurrence of an acid igneous intrusion in a close vicinity to the Cianowice 2 borehole (approximately 1.5–2.0 km away), which could be a source of the hydrothermal solutions.
