HYDROTHERMAL Sb-Au MINERALIZATION IN THE STRAZOVSKE VRCHY MOUNTAINS (MALA MAGURA, WESTERN CARPATHIANS)

Rok, strany: 2003, 207 - 216

Sb-Au mineralization in the Mala Magura Mts. was found in the vicinity of the Chvojnica village. Mineralization occurs in quartz-carbonate veins and disseminated zones in the Variscan granitoids and highly-metamorphosed rocks. Paragenetic associations of Sb-Au mineralization are close to other deposits of this type in the Tatric tectonic unit (Male Karpaty Mts. Nizke Tatry Mts. etc.) The mineralization was formed during three stages. The pyrite-arsenopyrite-gold mineral stage is the oldest one. The arsenopyrite geothermometer gives a temperature range of 385–465 °C. Younger stages are the sphalerite-galena-tetrahedrite (2nd) and stibnite-sphalerite-sulphosalts (3rd) mineral stages. A substantial part of the sphalerite of the 2nd mineralization stage shows ”chalcopyrite disease”. Common association of pyrrhotite and native antimony observed in the 3rd mineralization stage indicates low aS₂ and fO₂ values of the ore-forming fluid. Furthermore, the 3rd mineralization stage comprises Fe-bearing minerals (jamesonite, pyrrhotite and berthierite), which indicate Fe-rich environment. Primary gold occurs in two generations differring in Ag content.
