caption_attribution_description: Blue diopsidite skarn (tumble-polished specimen) from the Neoproterozoic of the Dovyren Highlands, eastern Siberia, Russia. Skarn is a coarsely-crystalline, contact metamorphic rock. The attractive rock shown here is a rare variety of skarn dominated by bluish-colored diopside pyroxene (“violane” or “violan”) ((Ca,Mg,Fe)₂Si₂O₆). Such rocks are called diopsidite skarn. Geologic origin &amp; context &amp; age: magnesium skarn formed by metamorphism of dolostone xenoliths by a gabbro-peridotite layered intrusion, Yoko-Dovyrensky Massif, Neoproterozoic, ~700 Ma. Locality: Dovyren Highlands, Buryatia Republic, Transbaikalia, eastern Siberia, Russia.
context_page_description: The Republic of Buryatia is a federal subject of Russia, located in Siberia in Asia. Formerly part of the Siberian Federal District, it has been a part of the Russian Far East since 2018. Its capital is the city of Ulan-Ude. Its area is 351,300 square kilometers with a population of 972,021.
context_section_description: Mongolic-related Slab Grave cultural monuments are found in Baikal territory. The territory of Buryatia has been governed by the Xiongnu Empire (209 BC-93 CE) and Mongolian Xianbei state (93-234), Rouran Khaganate (330-555), Mongol Empire (1206-1368) and Northern Yuan (1368-1691).
  Medieval Mongol tribes like Merkit, Bayads, Barga Mongols and Tümeds inhabited in Buryatia. Today Buryat-Mongols populate the territory of Buryatia.
  The area of the present-day Buryatia was first colonized in the 17th century by Russians in search of wealth, furs, and gold.
  In 1923, the Buryat-Mongolian Autonomous Soviet Socialist Republic (Buryat: Буряадай Автономито Совет Социалис Республика; Russian: Бурятская Автономная Советская Социалистическая Республика) was created as a result of the merger of State of Buryat-Mongolia and Mongol-Buryat Oblasts. In 1937, Aga Buryatia and Ust-Orda Buryatia were detached from the Buryat-Mongolian ASSR and merged with Chita and Irkutsk Oblasts, respectively. In 1958, the name "Mongol" was removed from the name of the republic. The Buryat ASSR declared its sovereignty in 1990 and adopted the name Republic of Buryatia in 1992. However, it remained an autonomous republic within the Russian Federation. On 11 July 1995 Buryatia signed a power-sharing agreement with the federal government, granting it autonomy. This agreement would be abolished on 15 February 2002.
