Genetic relationship of minerals to fluid circulation in the Polish Carpathians – the Bystre Slice case study

Abstract

As so ci ate Ed i tor: Tomasz Bajda Field work con ducted in the area of the Bystre Slice of the Pol ish Carpathians has al lowed the rec og ni tion and map ping of min eral as sem blages with re spect to a mélange zone. Ore min er al iza tion in the Cre ta ceous and Paleogene zones of the Bystre Slice, an a lyzed geochemically, petro graphi cally and min er al og i cally, in cludes epigenetic min er als such as realgar, orpiment and cin na bar, here char ac ter ized and their parageneses de scribed. Fluid in clu sions are dis tin guished in newly discov ered realgar crys tals, and microthermometric re sults al low a min er al og i cal se quence in the study area to be pro posed. The new min eral goyazite, pre vi ously not de scribed in the Carpathians, oc curs as solid in clu sions in the realgar crys tals, co-oc cur ring with kaolinite. The min er al iza tion likely re lates to a mag matic anom aly pres ent in the NE part of Slovakia in the West ern Carpathians south of Dukla in Po land, and a pos si ble sub-sur face subvolcanic body that deep ens to wards the E, the in ferred top of which lies at a depth of ~1 km. The min er al iza tion may be con nected with dis lo ca tions in the rock units.
