Ottorzhenets kimberlite body, Alakit-Markha, Daldyn-Alakit kimberlite field, Saha Republic (Sakha Republic; Yakutia), Eastern-Siberian Region, Russia

Isolated kimberlite body, hosted in Upper Palaeozoic rocks. It represents a shallow-seated fragment of the Yubileinaya pipe, cut off by a trap sill and displaced for several hundred meters. As a result of the dynamic effect of the trap sill, the Ottorzhenets body was delaminated, folded, and crushed, and then underwent hydrothermal and supergene alterations. The rock types identified in this body are comparable to those in the Yubileinaya pipe.
