Abstract
Ore-bearing coaly shales of the Lena auriferous region (Patom Highland) are distinctly controlled by lithostratigraphic and structural factors. They are confined to carbonaceous and carbon-bearing (carbonate–terrigenous and terrigenous) lithologic varieties of primarily Au-rich black shales. However, the location of ore-bearing shales within these units is governed by structural factors. Gold mineralization and synore alterations are related to the tectonometasomatic reworking of substance of the geochemically favorable protoliths.
