| Abstract: | Anomalous concentrations of dissolved gases, exceeding their background values by an order of magnitude or more, are recorded in the surface and ground waters of the Birofeld Graben of the Middle Amur sedimentary basin. The main geological factors that influence the formation of the gas composition and gas saturation of waters are determined. The gas-geochemical indicators for the dissolved hydrocarbon gases, which make it possible to estimate their genesis and prospects for the oil-and-gas contents of the Birofeld graben, are specified. |
