| Abstract: | There are a lot of organic matters in the Jinding lead-zinc deposit. The organic matters can be distingushed as three types by their occurrence, a) the indigenous type, b) the type of hydrothermal metamorphism.c) the type of migration. The studies of organic geochemistry demonstrate that the indigenous organic matters in the host rock are in immature stage or low-grade mature stage. The thermal degradation of the indigenous organic matters resulted from ore-bearing hydrother-matism, then the anomaly of hydrothermal maturation is formed. As a result of the reaction of the ore-bearing hydrothermal fluid a lot of hydrogen sulfides are produced by partial organic matters.This process generates precipitation and enrichment of the metallic sulfides. Studies on the distributive form of thermal mature anomaly of the organic matters are a great help to research and exploration of the Jinding-type lead-zinc deposit. |
