- Ústav geologie a pedologie, Mendelova univerzita v Brně
Sheeve Ovo is one of the largest coal deposits in Mongolia where the largest coal mine is operated with a designed capacity of more than 5 Mt annually. This paper brings information about the sedimentary host rock associations supported mainly by detail geological research and survey field work. The Sheeve Ovo district is situated at the edge of the north-east end of the Choir depression enclosed on metamorphic bedrock. The host syncline is more than 10 km wide and extends about 15 km across NE-SW direction. Within the basin, 3 main Precambric strata can be distinguished in accordance to their lithologic contents: (1) upper mudstone strata, (2) quartzite sandstone strata, (3) lower quartzite-mudstone strata. The Precambrian rocks are overlaid with later Lower-Paleozoic sedimentary rocks which are followed with a continuous rock sequence of Mesozoic and Menozoic age. There are 8 main coal seems between clastic rocks of cretaceous age.
