Historical and geological model of uranium ore genesis in the Aldan and Anabar shields, the Siberian platform

The paper shows the possibility of identifying in old structural and stratigraphic unconformity zones in the shields of the Siberian Platform of “unconformity-type” deposits, similar to the Athabasca uranium province, based on a comparative historical and geological analysis of uranium ore formation within the Canadian Shield of the North American Platform, the Aldan and Anabar shields of the Siberian Platform. In order to increase uranium reserves of the Russian Federation by identifying large deposits with high-grade, contrasting ores, it is proposed to carry out regional predictive and metallogenic surveys for uranium in old structural and stratigraphic unconformity zones of the Aldan and Anabar shields.
Keywords: historical and geological model, uranium, ore formations, Aldan and Anabar shields.
