Abstract
Physico-chemical analysis of the mineral parageneses of argillic type of altered rocks in Pod Polomom porphyry copper system of Javorie, Slovackia. In the zone of advanced argillizaton of the rocks occurring in the shallow parts of the porphyry copper system of Javorie, the Pod Polomom quarry, the following associations are presented: quartz + pyrophyllite, quartz + pyrophyllite + diaspore, quartz + pyrophyllite + topaz, quartz + pyrophyllite + diaspor + topaz, quartz + topaz, quartz + zunyite. A physico-chemical analysis of the mineral parageneses has been applied in order to distinguish the equilibrium mineral association (mineral parageneses), that appear as important for the genetic classifications. The prognostic paragenetic diagram obtained is the basis for analysis of physico-chemical formation conditions of mineral parageneses rich in aluminium non-sulphate mineral phases. Beside the acid-sulphate type of alteration the pyrophylite-diaspore and fluoride (topaz-zunyite) types of alteration are assigned to the advanced argillization. The facial analysis allows to identify the pyrophyllite-diaspore, topaz and zunyite facies of the secondary quartzite formation that correspond to those types of alteration. This investigation proposes unifying features of the two commonly accepted genetic classifications according to types of alterations and to formations respectively.
