Kontrakcija zapremine granitoida Bukulje usled hidrotermalnih alteracija: kontrolni faktor prostornog položaja mineralizacije urana

The volume contraction of the Bukulja granitoide due to hydrothermal alteration: The controlling factor of the Uranium mineralization in the parent rock

Abstract

The influence of hydrothermal activity. before and during ore deposition in Bukulja granitoide is measured by determination of volume contraction of the parent rocks. On the basis of the field investigations, experimental laboratory measurements and appropriate model the total volume chance of the solid phase (∆V_r) was calculated assuming that all reaction components are known for dominating alteration processes. The obtained results were scaled to 1 mole of each altering mineral (∆V_r/n) in the system.

There is a direct dependence between the volume contraction of the granitoide and the localizationand amount of the uranium containing mineralization in the parent rock.
