| Abstract: | In this paper some evidence is collected for water rock interactions during the mineralization of sandstone hosted. copper deposits in Central Yunnan Province, China, based on studies of field geological occurrence, petrochemistry, organic petrology, element geochemistry, and organic geochemistry. Mechanism of water rock reaction discussing in the present paper involve filtration, hybridization, replacement, metasomatic alteration, redox and boiling. The results obtained demonstratethat:(1) the water rock interactions were responsible for the mineralization of copper , and the reactions carried out in two stages:diagenetic stage and transformation stage;(2) during the diagenetic mineralization, filtration, hybridization and metasomatic alteration were predominant;however, boling and redox were predominantly important during the transformation;(3) water rock reaction during transformation superimposed, at some extent, on products formed during diagenetic interactions. |
