About the rocks of a small part of the gold-bearing area in the Semipalatinsk region

Abstract

This note is the result of a study of the general nature of the primary gold deposit in the summer of 1911 at the mines of the South Siberian Gold Mining Partnership, located on the Laila River, in the Kuludzhunsky volost of the Ust-Kamenogorsk district. The mine area occupies 22 square versts. From it, small tours were made in different directions, mainly to the nearby granite Kaindinskii forest, and thus the entire examined area is approximately 100 square versts. The genesis of gold-bearing quartz veins is being clarified. Their appearance is probably associated with the intrusion of granites. Veins filling cracks, consistent with the strike of rocks and caused by primary dynamic processes, were formed as a result of thermal activity (see article).
