摘要
沿河大漆铜矿为一沉积改造型铜矿床,矿体产出严格受地层控制,赋存在三叠系巴东组第二段紫红色砂岩与灰、灰绿色砂泥岩中。通过对矿床地质特征、矿石特征、矿床成因等特征的初步分析,认为矿床在形成过程中,沉积作用起主导因素,成岩期的各种地质作用对矿床的形成起进一步的富集作用,加上后期的氧化作用使其再富集。
Daqi copper mine is a sedimentary reformed copper deposit,the ore occurrence is controlled by stratum strictly,occurs in red sandstone,gray and mignonette sandstone and mudstone.By study the geologic characters,ore characters and genesis,it＇s thought that during the formation of deposit,sedimentation plays the most important role,each geologic process in the diagenetic period concentrated the deposit,the later oxidation made it more concentrated.
