Abstract

In Late Carboniferous and Late Permian, coal was accumulated in western and southern Mongolia and the southern half of Lake Zone. During Early Jurassic, deposition took place in the west, east and north parts of the territory of Mongolia. The final stage of coal accumulation started in Eastern Mongolia at Early Cretaceous. The survey area lies within the Choir depression of Choir-Nyalga basin, coal-bearing province of Eastern Mongolia. Choir depression includes Uvdugkhudag, Ulaanmiur, Ikh Ulaanmiur and Shivee-Ovoo brown coal deposits (Bat-Erdene 1994).
