Analytical results of the soil adsorbed hydrocarbons in the Kengtou gold deposit

In 2022, a soil adsorption hydrocarbon profile with a length of 800 meters was arranged perpendicular to the F10 fault in the Kengtou gold deposit.. When collecting soil samples, pass through the humus layer (layer A) and collect in the leachate layer (layer B). Two sub sample pits are arranged within a range of 3m on the side of the main sample pit, with a distance of 50m from each point. A total of 17 samples are collected by mixing a portion of each pit into one sample. The sample was processed to 160 mesh and tested using the acid hydrolysis method at China Nonferrous Guilin Mineral Geology Research Institute Co., Ltd Agilent 6820 gas chromatography was used, with DB-1 (length 15 m, inner diameter 0.53 mm) column, FID detector, and nitrogen gas As an auxiliary gas, hydrogen is the combustion gas and air is the auxiliary gas.
