摘要
通过干酪根分析,首次在铜矿石中发现与铜硫化物密切共生的有机质.铜矿石严格受富含有机质的白云石大理岩控制.沉积阶段铜质虽有富集,但铜硫化物的沉淀主要发生在成岩阶段.认为黎溪式铜矿床应属有机-成岩成因.
From an analysis of kerogen, organic material was found for the first time closely associatedwith copper-bearing sulfides in copper ores. The copper ores strictly controlled by dolomite marblerich in organic materials. At the sedimentary stage, the copper ores had been concentrated to someextent, but the deposition of sulfides of copper mainly occurred at the diagenetic stage. It is therefore believed that the Lixi copper deposit belongs to organogenic-diagenic type.
