Колвицкое месторождение (геология, вещественный состав руд)

Колвицкое месторождение (геология, вещественный состав руд)

Abstract

Findings on the geological structure, texture, mineral and chemical structure of the Kolvitsa titanomagnetite ore deposit have been reported with a history of discovery and exploration attached. For the first time, a full composition of minerals and enclosing rocks of the deposit has been presented. It has been shown that the titanomagnetite mineralization is accompanied by a copper-nickel sulfide mineralization where the principal minerals are pyrrhotine, pentlandite, bornite, cubanite, walleriite, and makinavite. High contents of nickel, copper and cobalt impurities are caused by sulfides of the titanomagnetite ore. On this basis the Kolvitsa iron-titanium-vanadium ore field has been proposed to be considered a complex Fe-Ti-V-Ni-Cu-Co deposit.

Приведены данные о геологическом строении, текстурах, минеральном и химическом строении Колвицкого месторождения титаномагнетитовых руд. Рассмотрена история открытия и изучения месторождения. Впервые охарактеризован полный минеральный состав руд и вмещающих пород. Показано, что титаномагнетитовое оруденение сопровождается сульфидным медно-никелевым, в котором главными минералами являются пирротин, пентландит, борнит, кубанит, валлериит и макинавит. Присутствие сульфидов в титаномагнетитовой руде обусловливает высокое содержание примеси никеля, меди и кобальта. На основании этого Колвицкое месторождение железо-титано-ванадиевых руд предлагается относить к комплексным Fe-Ti-V-Ni-Cu-Со месторождениям.
