NAPHTHIDES IN LOWER DEVONIAN BASALTS IN THE NORTH MINUSINSK DEPRESSION

Abstract

Lower Devonian amygdaloidal basalts in the North Minusinsk Depression contain abundant inclusions of natural solid bitumens [1-3]. Liquid hydrocarbon fluids were found in Lower Devonian rocks on the left wall of the Sokhochul Ravine at the junction of Hercynian tectonic structures (southern blank of the North Minusinsk Depression) with Salairides of the Kuznetsk Alatau Mountains.
