Outcrops of Carnian volcanogenic–sedimentary diamond-bearing rocks (tuffs and gravelites). They extend to the mouth of the Olenyek River and further along the coast of the Laptev Sea to the Eastern Taimyr. The following hypotheses have been critically considered as sources of diamonds: redeposition and long-range transport from diamond-bearing reservoirs, redeposition from the weathering crust of kimberlites of near-demolition, hydroexplosive clastic origin of rocks, and the direct volcanogenic–sedimentary genesis of diamond-bearing deposits.
