Where:  Novosibirsk (Altay) Russia

Date:  26-30 August 2011

Conference Web Site:  http://deepcarbon.net/content/3rd-deep-carbon-cycle-international-workshop-dco-3

This conference focused on five topics:

  1. Kerogen in Earth’s history with emphasis on Precambrian oil deposits;

  2. Carbonatitic melts and brines – the role in alkaline rocks origin including kimberlites and lamproites (using
      fluid [melt] inclusions and geochemical data);

  3. Coexisting mineral and fluid inclusions in diamonds with an emphasis on deep diamonds;

  4. Experimental studies of carbonatitic melts and CO/CO2 incorporation into high-pressure phases. 

  5. Thermodynamical and geochemical modeling of subduction zones for estimating the carbon cycle;

Additional topics related to deep carbon studies can also be included.

Location:
The conference was held in the Altai mountains in the region near the natural archelogical treasure Denisova Cave (Ayu-Tash).  The travel will be organized by mini-buses from Novosibirsk and it takes nearly 6 hours.  All participants will be taken by bus before and after the conference.  

Denisova Cave (Денисовапещера, also Ayu-Tash) is a cave in the Bashelaksky Range of the Altai mountains, Siberia, Russia. The cave is of paleoarchaeological and paleontological interest. Bone fragments of the Denisova hominine, sometime called the "X-woman" (referring to the maternal descent of mitochondrial DNA) originate from the cave, including artifacts dated to ~40,000 Before Present (BP). The cave is located in a region thought to be inhabited concurrently in the past by Neanderthals and modern humans.

Located in Altai Krai, at the border of the Altai Republic some 150 km south of Barnaul, the next major city.Cave sediments are rich with remnants of animals including extinct ones. Remains of species of large and medium sized mammals have been found, as well as remnants of reptiles, 50 bird species and other vertebrates.

In the 18th century, the cave was inhabited by a hermit, Dionisij (Denis), and was named after him, while the indigenous Altay people call it Ayu-Tash (Bear Rock)

Scientists from the Institute of Archaeology and Ethnology of Novosibirsk have investigated the cave. Among the artifacts which had been left about 30,000 to 48,000 years ago (strata 9 -11), bones were identified. One such bone was a piece of phalanx of a child that was analyzed by Svante Pääbo and coworkers from the Max Planck Institute for Evolutionary Anthropology in Leipzig; its mitochondrial DNA revealed a structure that differs from known human patterns and has been ascribed to Denisova hominin, apparently an extinct hominin species.

Novosibirsk is Russia's third-largest city, after Moscow and Saint Petersburg, and the largest city of Siberia. It is the administrative center of West Siberian federal district of Russian Federation. Novosibirsk population is about 1.4 million (January, 2009). The city is located in the southern portion of the West Siberian Plain and occupies an area of 477.2 square kilometers (184.2 sq mi). The city stands on the banks of the Ob River – one of the biggest rivers of the Eurasia. To the south of the city lie the Golden Mountains of Altai.
