Tunguska Basin

The Tunguska Basin is a sedimentary basin, in Siberia.

Geography

Much of the Siberian Traps Large Igneous Province is inside.[1]

The area is of about 400,000 square miles (1,000,000 km2) in Krasnoyarsk Territory and Sakha Republic, between the Yenisei and Lena rivers. It contains a huge untapped coal reserve. Its main settlements there are Norilsk, Igarka, and Yeniseisk. The Tunguska rivers cross the basin. On June 30, 1908, near the Stony Tunguska River the Tunguska Event took place.[2]

Geology

Boreholes in the Tunguska Basin indicate ubiquitous and abundant sills, which have great lateral extension.[3]

The Tunguska Basin makes up much of the Siberian Craton and has several subbasins.[4]
