Diamond mine

Contacts of the kimberlite body with the host dolomites of the Turgut Formation of the Upper Vendian are hidden from three sides under steeply falling talus. The body is elliptical in shape, with its long axis oriented to the northwest. The size of the pipe is 20 × 30 m. The Obnazhennaya pipe belongs to the Middle Mesozoic era of kimberlite formation. It is proved by isotopic methods and confirmed by the age of the present fragments of belemnite rostra of the genus Pachyteuthis, characteristic of the Upper Jurassic and Lower Cretaceous and attributed to the Jurassic and Late Jurassic Cylindroteuthis species. It is also indicated using a xenolith with wood fragments, defined as Protocedroxylon, which is of Jurassic-Lower Cretaceous age.

The Obnazhennaya pipe consists mostly of pyroclastic kimberlite with high Mg, low Ti. The relatively high freshness of the kimberlites - partial preservation of fresh olivine, high content of unaltered mantle xenoliths in the Obnazhennaya pipe.
