Минеральный состав зон пиритизации кыввожского района (Средний Тиман)

Минеральный состав зон пиритизации кыввожского района (Средний Тиман)

Abstract

Минералогическое изучение зон сульфидной минерализации, широко развитых в Кыввожском районе Среднего Тимана, показало присутствие в них наряду с пиритом галенита, халькопирита, сфалерита, пирротина, кобальтина, ковеллина, монацита, ксенотима, минералов висмута и теллура. Весьма характерны также для данного района минералы редких земель: монацит, ксенотим; отмечаются минеральные фазы Ag-Se, Pb-Nb, Th-U, Sr-Tb. Выделяются две основные стадии минералообразования: ранняя - пиритовая - и поздняя - халькопирит-галенит-сфалеритовая - с сопутствующими минералами редких металлов и редких земель. Зоны пиритизации заслуживают внимания при поисках коренных месторождений золота, которое, вероятнее всего, относится к поздней стадии минералообразования. Наиболее перспективны участки с наложенной халькопирит-галенит-сфалеритовой и редкометалльно-редкоземельной минерализацией.

Mineralogical study on sulfide mineralization zone abundant in Kyvvozh region of the Middle Timan showed that along with pyrite it contains galena, chalcopyrite, sphalerite, pyrrhotite, cobaltite, covelline, monazite, xenotime, Bi and Te minerals. Rare earth minerals such as monazite and xenotime are quite common. Ag-Se, Pb-Nb, Th-U, Sr-Tb mineral phases are noted. We can reveal two main stages of mineral formation: early pyrite stage and late chalcopyrite-galena-sphalerite stage associated with rare metals and rare earth minerals. Gold is most likely to be related to late stage of mineral formation process. Pyritization zones should be taken into consideration for gold deposits exploration. Areas with epigenetic chalcopyrite-galena-sphalerite and rare metal rare earth mineralization are the most perspective.
