Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The article considers the geological structure of Kogodai copper massive sulfide deposit in the Kurchum block, which is an integral part of the Irtysh shear zone. It is shown that the geological structure of the site involves feldspar quartz-mica and amphibole-feldspar-mica crystalline schists, gneisses with frequent horizons of amphibolites. Mineralized zones confined to the contact of amphibolite bodies with gneisses on terrigenous rocks are noted, granitoids in different phases of intrusion including dikes and various granite and quartz porphyries are also considered. The spatial contiguity of geological structures of different ages and compositions subject to intense metamorphic transformations is emphasized. This article presents the features of the copper massive sulfide deposit, the composition of the ores and the connection with the geological and structural-tectonic factors that contributed to its formation.
