UDC (553.973:552.1):551.732.2/.732.3(571.5-12) MATERIAL AND PETROGRAPHIC COMPOSITION OF ROCKS AND ORGANIC MATTER OF THE “KUONAMKA” FORMATION
The paper provides the description of material and petrographic composition of rocks and organic matter in the bituminous argillaceous-carbonaceous Middle Cambrian “Kuonamka” Formation, which was formed at the southwestern margin of the Siberian Platform and is unique in sapropelic organic matter content (up to 30%). The formation was deposited in a huge epicontinental marine basin extending from west and southwest to the barrier reef tract between the Anabar and Aldan anteclises. Paleogeographic map and lithofacies crosssection of the formation were generated based on reference sections. The paper contains colour photographs of rocks and organic matter from different facies zones.
Key words: Siberian Platform, “Kuonamka” Formation, sapropelic organic matter, depositional facies.
