Abstract

Геохимия серы и сернистых соединений куонамского комплекса нижнего и среднего кембрия (восток Сибирской платформы)

Highlights

The black shale Kuonamka complex of the Lower and Middle Cambrian (Bakhturov et al, 1988; Kontorovich, Savitsky, 1970; et al.), widespread in the north and east of the Siberian platform, is considered by geologists as one of the main possible sources of oil and gas (Geochemistry of oil and gas ..., 1972; Savitsky et al, 1972; Bazhenova et al, 1981; et al.), as well as the resource of oil shale (Geology of deposits ..., 1968; Gurari et al, 1987;Kashirtsev, 2003; et al.) and the products of their chemical processing
In comparison with the sediments of the Siberian platform depleted in organic matter (OM), the rocks of the Kuonamka complex are enriched in sulfur (Savitsky et al, 1972; et al.)
The change in the content of sulfur and sulfurous compounds in the Cambrian sediments indicates that the rocks under study at the stages of sedimentation and diagenesis were formed under different oxidationreduction conditions

Summary

Introduction

The black shale Kuonamka complex (formation) of the Lower and Middle Cambrian (Bakhturov et al, 1988; Kontorovich, Savitsky, 1970; et al.), widespread in the north and east of the Siberian platform, is considered by geologists as one of the main possible sources of oil and gas (Geochemistry of oil and gas ..., 1972; Savitsky et al, 1972; Bazhenova et al, 1981; et al.), as well as the resource of oil shale (Geology of deposits ..., 1968; Gurari et al, 1987;Kashirtsev, 2003; et al.) and the products of their chemical processing. The study of sulfur in rocks and OM is necessary to assess the quality of black shale and “synthetic” petroleum products, to develop efficient and environmentally safe technologies for the extraction and processing of non-conventional hydrocarbon raw materials.
