Abstract

Abstract

One of the most important ore fields in Qinling multi-metallic ore-forming belt is Xicheng Pb-Zn deposit which is controlled strictly in the Middle Devonian series. Viewing from organic geochemistry, the correlation between ore-forming elements and organic matter, organic molecules, the analysis of neutron activation for asphalt, ore, wall rock and the experiment simulation, this paper probes into the role of organic matter in the forming process of Xicheng Pb-Zn ore field. The analysis results for organic geochemistry of fresh rock and ore samples selected systematically show that the content of chloroform bitumen "A" from the cherts and the silicified limestones involved in mineralization is lower than that from the unmineralized rocks. While GC-MS-MS analysis of rocks and ores suggests that the dominant carbon is almost nC₁₈ in all mineralization rocks (siliceous rocks and limestone rocks). Organic molecules of the rocks relevant to mineralization and limestones are mainly pentacyclic triterpene. Studies on the correlation analysis between organic matter and ore-forming elements show that the contents of Pb and Zn have striking negative correlations with aromatic hydrocarbon and chloroform asphalt "A" and positive correlation with non-hydrocarbon and organic sulfur/(organic carbon×1.22). The contents of Pb and Zn have positive correlations with the abundances of some organic molecules, whereas they have negative correlations with the ratios of some organic molecules. The analysis results of neutron activation for asphalt, ore, wall rock reveal that the asphalt has a close relationship with ores, and that the organic matter comes to the ore-forming site together with ore-forming elements at the reformed mineralization stage. The dissolution ability of Pb-Zn, the ability of the rock samples of releasing ore-forming elements have been increased because of the adding of organic water in hot water fluid. Therefore, it can be inferred that the organic matter played an important role in the formation of lead-zinc deposits in Xicheng ore field.
