At this occurrence, diamonds are also found in carbonatitic rocks. The latter are associated with pyroxenites, alkaline gabbroids, pulaskite, and nepheline syenite.
Diamond ore bodies, hosted in metasedimentary rocks intercalated with metavolcanic rocks within an ultra-high pressure (UHP) metamorphic terrane (Kokshetau massif), formed during a Palaeozoic continental collision.

The ore bodies consist of feldspathic gneisses and quartz-rich rocks intercalated with calc-silicate rocks, marbles, and layered garnet pyroxenites with enclosed lenses of eclogite. The diamonds are typically 1-80 µm in diameter and occur as inclusions in virtually all rock-forming minerals, even though some of these minerals are unstable under the conditions of diamond formation. Diamonds are also preserved in chlorite-sericite aggregates that replace garnet, and it is found in sericite pseudomorphs after plagioclase in garnet-biotite and garnet-two-mica gneisses. They show no connection with the eclogites. Instead, the diamond ore bodies occur within ductile and semi-ductile shear zones that cut the eclogite facies rocks at acute angles.

Located about 17 km west of Lake Kumdykol.
