| 摘 要： | 祁漫塔格成矿带是青海省重要的铜多金属成矿区带,虎头崖地区铜铅锌矿床由虎头崖和迎庆沟两个相连矿区组成,近年来找矿取得了很大进展,但该区矿床成因类型尚有争议。通过详细的野外观察,从不同角度收集证据,厘定了矿床的成因类型:一是与印支期岩体、奥陶—志留系滩间山群、上石炭统缔敖组有关的热液型;二是与中元古界狼牙山组有关的喷流沉积-热液叠加改造型。同时,对矿床控矿因素进行了分析,并建立了找矿标志,以指导找矿。 |
| 关 键 词： | 喷流沉积 热液型 成矿类型 铜铅锌矿床 虎头崖 青海省 |

| Abstract: | Qimantag metallogenie belt is very important copper-polymetallic metallogenic beltin Qinghai. Copper-lead-zinc deposits in the Hutouya area composed of Hutouya and Yingqinggou deposit. The deposit prospecting has made great progress in recent years, but the genetic types of deposits remains controver- sial. Through detailed field observations, we collected evidence from different angles, and then determined two genetic types for the deposits- one belongs to hydrothermal deposit related to Triassic bodies, Tan- jianshan group in Ordovician to Silurian, and Di＇ao Formation in Late Carboniferous~ the other reIated to Mesoproterozoic Langyashan Formation belongs to SEDEX-hydrothermal superimposition-transformation deposit. At the same time, ore-controlling factors were analyzed and prospecting criteria was established to guide the exploration. |
| Keywords: | SEDEX hydrothermal ore-forming type copper-lead-zinc deposits Hutouya Qinghai |
