Abstract

W złożu pirytu w Wieściszowicach zaobserwowano nieznaną dotychczas mineralizację żył kwarcowych. Wydzielono trzy etapy mineralizacji. Pierwszy etap reprezentują: pirotyn, piryt i kwarc. Minerały drugiego etapu: chalkopiryt, bornit, sfaleryt, galeria, tetraedryt, jamesonit i syderyt wypełniają puste przestrzenie i cementują spękania kataklastyczne w pirycie i w kwarcu. Minerały trzeciego etapu: markasyt, chalkopiryt, sfaleryt, galena, bournonit, jamesonit, boulangeryt, dolomit i kalcyt powstają w wyniku metasomatozy minerałów etapów wcześniejszych. Stwierdzono, że polimetaIiczne, śladowe okruszcowanie w złożu pirytu jest efektem mobilizacji pierwiastków w procesach metamorfizmu.NEW DATA ON POLYMETALLIC MINERALIZATION OF QUARTZ VEINS IN PYRITE DEPOSIT FROM WIESZCISZOWICE (LOWER SILESIA)Numerous quartz. veins occur in pyrite-bearing chlorite-sericite schists belonging to eastern part of metamorphic cover of the Karkonosze granite. The veins are epigenetic in relation to the surrounding rocks. Two types of veins are distinguished: one, formed of milk-white quartz, feldspar and sometimes pyrite, and another, comprising veins mineralized with gray quartz and with hitherto unknown polymetallic mineralization accompanied by siderite, dolomite and calcite. The assemblage of ore minerals comprises: pyrite, pyrrhotine, marcasite, chalcopyrite, sphalerite, galena, tetraedrite, bournonite, boulangerite and jamesonite. Textures, structures and typomorphic features evidence three-stage precipitation of these minerals. The stages are separated by phenomena such as cataclasis and metasomatosis; Mineral paragensis of one of the stages is also present in surrounding pyrite-bearing rocks where it heals cataclastic fissures in idioblasts FeS2.The origin of this polymetallic mineralization of quartz veins may be related to mobiIization of elements in result of processes of metamorphism or more precisely, metamorphic hydrothermal activity.
