Porphyry Mo-Cu-W mineralization within precambrian-paleozoic rocks - prospectivity analysis of the border zone of the upper silesia and mał opolska blocks Porphyry Mo–Cu–W mineralization is associated with the boundary zone of the Upper Silesia and Ma³opolska blocks. It isencountered within Ediacarian and Silurian metasediments, as well as in Ordovician, Silurian and Devonian carbonates and siliciclastics,intruded by granitoids and porphyry dikes. Ore mineralization is represented by chalkopyrite, molibdenite and scheelite forming veinlets, im-pregnations and disseminations. Investigation of 66 km of cores from 284 prospective drill holes (done till 1992) provided new data represent-ing the distribution of mineralization on a regional scale. Based on the contours of metal average contents, fve prospective areas (Nowa Wieœ ̄arecka–Myszków–Mrzyg³ód, excluding Myszków deposit, ̄arki–Kotowice, Zawiercie, Pilica and Dolina Bêdkowska) with porphyryMo–Cu–W mineralization have ...
