A Town of Passionarians

Almost a century ago, in the 1920-30s, a special commission of the USSR Academy of Sciences on the organization of regional affiliates denied the request of local governments in Siberia and the Far East of the country to create local affiliate divisions. The stated reason was that it was impossible “to deploy Academicians to the specified cities without the destruction of the Academy of Sciences as such, and selecting new Academicians, forcing them to live and work in a specified city, is impossible...

Rounded by the Time... The Origin of Siberian Craton Diamonds

... potential of Siberia is far from being exhausted, but efficient search for new deposits demands comprehensive information on the origin of this hardest and most expensive carbon allotrope. In addition to the commonly known diamonds originating from kimberlites, placers of the Siberian Craton contain unusual crystals whose primary sources are unknown Siberian diamonds were first found in gold placers in the drainage area of the Bol’shoi Pit River, on the Yenisei Range, in the present Krasnoyarsk ...

The Discovery of Zarnitsa: The Dawn of Siberian Diamonds

... history of famous deposits. He is one of the discoverers of the Tomtor rare metal deposit. In the late 1950s, he took part in prospect evaluation works in northwestern Yakutia. His Candidate (PhD) thesis was dedicated to the structural control of Yakutian kimberlites Targeted search for diamonds commenced in the USSR in 1938. The researcher of the Geological Institute A.P. Burov wrote a memo recommending a series of studies on the comparison of the geology of diamondiferous regions in the world with ...

The First Diamond of Manchary

... the prospect of the southeastern Siberian Craton as a new diamondiferous region of Russia More than 25 years ago, researchers of the Diamond and Precious Metal Geology Institute (DPMGI) discovered geophysical anomalies of pipe type, presumably, kimberlites, in Central Yakutia. In 2007—2008, prospecting drilling conducted by Yakutskgeologiya enterprise in the region of the Tamma River, 100 km south of Yakutsk, revealed the first kimberlite pipe in the southeastern Siberian Craton. It was named ...

Diamond Road Three Billion Years Long

... crystals grow in the Earth’s depths and, second, how they are brought up to the Earth’s surface. Practically all primary diamond deposits are related with volcanic pipes formed by kimberlite breccias *, which is why they are called kimberlite pipes. Kimberlites are rocks of mantle origin formed at vast depths as a result of the complicated process of partial melting of the rocks composing various layers of the Earth’s mantle. A lot of kimberlite melts form in the layers below the boundary of graphite ...
