GEOLOGICAL AND GEOMORPHOLOGICAL CONDITIONS OF OIL BITUMEN DEPOSITS PLACING AND BITUMEN OUTPOURING IN MIDDLE SHESHMA RIVER BASIN, TATARSTAN

A brief overview of the geology of heavy oil, bitumen and oil sand deposits

Introduction There are three major oil sand areas in Canada, all in Alberta. There is also an oil sand deposit on Melville Island in the Arctic. The three major oil sand areas are from highest to lowest volume of reserves-in-place (AEUB 2003) Athabasca, Cold Lake and Peace River oil sand areas notwithstanding that bitumen reserves are also evident in subcropping carbonate rocks in Athabasca and...

Geological and Geochemical Features of Alborz Basin Coal Deposits, Iran

The Alborz coal basin is located in northern part of Iran. The coal deposits of Shahrood in eastern Alborz, Zirab in central Alborz and Abyek in western Alborz were studied as typical coalfields of the basin. Shemshak Formation which is the main coal-bearing sequence was formed during the Triassic-Jurassic in the basin. It consists of sandstone, siltstone, shale and claystone, which variedly al...

The Human Bitumen Study

Recently, the Human Bitumen Study has been finished (Schlüter, 2011). Including 500 workers from more than 80 construction sites it represents the world-wide largest study on adverse health effects caused by bitumen. The study answers a question that has been controversially discussed since decades: Bitumen exposed workers do not show higher levels of DNA damage than unexposed individuals. On t...
