| 中文摘要: |
| 四川省会理县海潮铜矿赋存于中元古界落雪组白云岩类和碳质板岩中，矿体呈层状、似层状及透镜状产出，产状与地层基本一致，局部具有分支现象；主要的围岩蚀变有褪色化、硅化、碳酸盐化和绢云母化；共有6个工业铜矿体，其中Ⅰ1和Ⅰ2矿体为主矿体；矿石自然类型以原生矿石为主，另有部分氧化矿石；根据赋矿岩石可分为板岩型和白云岩型。海潮铜矿床是中元古代裂谷环境下形成的热水沉积-改造型矿床。 |
| 英文摘要: |
| Haichao copper deposit occurs in the dolomitic rocks and carbonaceous plate of the Huili Group of Middle Proterozoic Luo Xue formation. Ore bodies are layeroid or lenticular coinciding with the strata and locally ramified. Decolorization, silicification,pyritization, carbonatization and sericitation are the main wall rock alteration. There are 6 industrial ore bodies of which ore bodyⅠ1andⅠ2 are major ones. The ore is dominated by primary ore with some oxidized and can be divided into plate type and dolomitic type according to the host rock. It is a hot water sedimentary-reworked deposit formed under the Proterozoic rifting enviorment. |
