Термо-ЭДС сульфидов: возможности метода и значение для минералогических исследований (на примере изучения пирита и арсенопирита золоторудных месторождений восточного и южного обрамления Сибирского кратона)

Abstract

On the example of studying the EMF of pyrrhotite, pyrite, and arsenopyrite from gold deposits of the Yana-Kolyma orogenic belt and the Bodaybo synclinorium, using the local determination method for polished sections, it is shown that this parameter for pyrite and arsenopyrite is an important genetic sign of the their origin. Thermoelectric properties of pyrite and arsenopyrite can be used to estimate not only the temperature of their formation but also the temperature parameters of their metamorphism, as well as to characterize the generation of these minerals. The development of local methods for measuring EMF contributes to the possibility of using them for genetic constructions, especially in the study of gold sulfide-impregnated and lode-veinlet mineralization within structures of different-age orogenic belts.
