Bitumen and Dispersed Organic Matter Related to Mineralization in Stratabound Deposits, South Chinarmian formations in South China. According to their genesis, and time of formation, the bitumen can be divided into the following types:.The textural-structural characteristics of organic matter and bitumen in stratabound ore deposits help in understanding their genesis and are useful in exploration

Bitumens in Uranium Depositsrude oils. Even if petroleum cannot be considered either as a source or as a carrier fluid for uranium, spatial relationships between source-rocks or oil fields with uranium deposits are evident. Uraniferous bitumens occur in various reservoir facies (sandstones, faults, breccias) and have been reco

Nature and Role of Organic Matter in Sandstone Uranium Deposits, Grants Uranium Region, New Mexico, uranium region, New Mexico. Because this organic material is the main ore control, determination of the nature, source, and time of emplacement of the organic material is critical to understanding the primary uranium ore deposits. Petrographic observations and radiometric ages for primary ore in the

In these deposits, uranium is associated with migrated organic matter which occurs as infillings of secondary porosity in deltaic sandstones. Sedimentologic, tectonic, petrographic, and geochemical studies have permitted a reconstruction of the geologic conditions in which uranium minerali

Interpretation of Thermal Mesophase in Vanadiferous Bitumens from Upper Proterozoic Lava Flows (Mítontary rocks (δ.C = −24.2 to –35.3‰). Mineral inclusions in the bitumen contain an anomalous amount of vanadium. The origin of bitumen may be sought in the processes of pyrolysis and the thermal effects of submarine basalt extrusion on the organic matter of Proterozoic sediments and stromatolites.

The combined results indicate that these uranium ore deposits are located in sandstone reservoirs associated with hydrocarbon traps and are capped by impermeable black shales which are also good oil source rocks.
