Abstract
The sedimentary cover of the Anabar Anteclise, Siberian Platform incorporates ore-bearing horizons of diverse ages with originally placer-related mineralization. Beds of coarse-clastic rocks with diamond occurrences are most widespread. Horizons with Nb–REE mineralization (including those hosting the well-known Tomtor stratiform ore deposit) and conglomerates with fine-grained native gold are less common. At least twice, at the Late Riphean–Vendian boundary and in the mid-Paleozoic, the anteclise experienced tectonic destruction related to alkaline–ultramafic (including kimberlitic) magmatism. This circumstance is responsible for the predominantly diamond and rare metal mineragenic specialization and local gold mineralization.
