The organic matter is closely related to the Lannigou gold deposit in southwestern Guizhou Province, where organic carbon and gold are collectively enriched in the fault zone.Studies on organic petrology and PIXE indicate that tar pitch, which is closely related to mineralization, adheres to the quartz vein wall Or filled with fine quartz veins.The pyrrole is rich in gold and closely interbedded with the gold-bearing pyrite and arsenopyrite, etc. Thermal simulation experiments show that 99% of the gold in the ore-forming fluid Enriched in the crude oil phase.The role of crude oil in the gold mineralization process is as follows: crude oil carries gold into the Triassic turbidite as a carrier of gold, encounters thermal decomposition and thermochemical reduction of the oxidising fluid, Release from crude oil and was reduced precipitation, enrichment of mineralization.
