中文摘要:
      青海省北祁连地区基性火山岩大面积分布,其中托莱山—达坂山成矿带早古生代基性火山岩具有形成与基性火山岩有关的Cu、Zn、Au、Pb等矿床的有利条件,近年来发现了多处铜锌矿床。通过对托莱山—达坂山基性火山岩岩石化学特征及阴凹槽塞浦路斯型铜锌矿的研究,认为阴凹槽铜锌矿产于大洋中脊环境下,其矿床分带明显,具有上锌下铜的特点。结合区域地质背景及成矿地质特征,初步认为托莱山—达坂山成矿带塞浦路斯型铜锌矿的找矿标志为:古老洋中脊、地球化学异常、岩石蚀变、物探异常和直接找矿线索。该矿床成矿特征及找矿标志的研究有利于推动青海省北祁连托莱山—达坂山成矿带早奥陶世阴沟群海相火山岩分布区塞浦路斯型铜锌矿的找矿工作。
英文摘要:
      Large area distribution of basic volcanic rocks in North Qilian area of Qinghai Province,and The early Paleozoic volcanic rocks in the Tuolai-Daba mountain metallogenic belt have favorable conditions for the formation of Cu、Zn、Au、Pb deposits related to basic volcanic rocks. Based on the research of chemical characteristics of volcano rock of Tuolai-Daban mountain metallogenic belt and Yin-Wacao Cyprus-type copper-zinc deposit, it is considered that the Yin- Wacao Cu-Zn deposit is a Cyprus type deposit occurring in the mid-oceanic ridge environment. Its ore deposit has obvious zonation and has the characteristics of upper zinc and lower copper. Combined with the regional geological background and metallogenic geological characteristics, it is preliminarily considered that the prospecting marks of the Cyprus type Cu-Zn deposits in the Tuolai-Daban mountain metallogenic belt are:a ancient mid-ocean ridge, geochemical anomaly, rock alteration, geophysical anomalies and direct prospecting clues. Study on metallogenic characteristics and Prospecting markers of the Deposit is propitious to promote the prospecting of Cyprus type copper-zinc deposits of the early Ordovician Yingou group marine volcanic rocks distribution area in the North Qilian Tuolai-Daban Mountain metallogenic belt in Qinghai Province.
