| 摘 要： | 锡铁山铅锌矿是目前青海省最大的有色金属矿山,其属于以沉积岩为主要围岩的海底热水喷流沉积型矿床,大理岩和(碳质)片岩可作为一种找矿标志,但不能作为矿床类型划分依据.该区经历了多次喷发旋回,因此形成的铅锌矿也具有旋回层,应在今后的地质勘查找矿中特别注意,一个旋回层的结束就代表成矿作用的结束.从钻孔的资料和岩心看,该区至少有7次喷发旋回,也许更多,也就是说有多次成矿作用.找矿的类型为喷流沉积型铅锌矿床. |
| 关 键 词： | 喷流沉积型 铅锌矿 大理岩 片岩 锡铁山 青海省 |

| Abstract: | Xitieshan lead-zinc deposit is the biggest nonferrous metal mine at present. It is a submarine hy- drothermal sedimentary-exhalative sedimentary deposit with the wall rock is sedimentary rock. Marble and carbon schist can be regarded as prospecting criteria, but not genetic type. There are several venting-flow- ing cycles, so the lead-zinc deposit also has cycles, And we should pay more attention to the cycle layers in geological prospecting in the future, because the close of the cycle was the close of metallization. Consider- ing from the drill core and data, there are seven exhalation cycies or more, which means multi-mineraliza- tion. The prospecting type is SEDEX lea＆zinc deposit. |
| Keywords: | sedimentary-exhalative lead-zinc deposit marble schist Xitieshan Qinghai Province |
