| 摘 要： | 西准噶尔仅有较少的斑岩型多金属矿床产出,这与其所在的巨型中亚成矿域的哈萨克斯坦环巴尔喀什-新疆西准噶尔成矿省这一重要的构造部位可能并不相称,有必要深入成矿研究和拓宽找矿思路。近年来笔者在该区的区域地质矿产调查和关键岩体初步研究的基础上,新发现了本文报道的吐克吐克、宏远和红山铜-钼矿点。据此类矿点以及包古图斑岩铜金矿的时空分布和赋矿岩体岩石类型等,提出建立达尔布特南构造岩浆带斑岩型Cu-Mo成矿区这一思路。今后的找矿思路是加强该带斑岩体时空分布、岩石成因类型、成矿物质来源以及矿化特征、成矿对比、区域构造等研究,建立找矿模型,用模型指导勘探找矿,而非仅仅利用物化探异常或仓促的大量勘探进行工程验证。

| Abstract: | The large Balkash-western Junggar metallogenic province of the huge Central Asia metallogenic domain have the large metallogenic capacity because of their obviously significant tectonic position, however, only rare occurrences of the porphyry copper-molybdenum(Cu-Mo)deposits were found out in West Junggar, China. And so it is necessary to enhance the prospecting researches and broaden the prospecting strategy in this area. Recent years, preliminary studies in terms of field geological mapping, mineral resources surveys, structural geology, and petrography, geochemistry and geochronology of several key plutonic bodies in West Junggar have allowed us to find some new ore occurrences including Tuketuke porphyry Cu(Mo)deposit, Hongyuan porphyry Mo(Cu)deposit and Hongshan porphyry Cu(Mo)deposit reported in this paper, and to characterize these porphyry deposits. Consequently, the southern Darbut teoctonic magmatic metallogenic belts can be presented in West Junggar based on the spatial and temporal distribution and the rock-type of ore-bearing intrusive bodies for these ore occurrences associated with the Baogutu Cu-Au deposit in the western segment of the belt. In order to acquire well prospecting effect and to provide new data for the regional tectonic evolution, it is believed that a lot exploration engineering layout only by the geophysical and geochemical anomalies or mineral survey is not so advisable, the further research on the spatial and temporal distribution, petrogenesis of the porphyries and the mineralization characteristics, metallogenic comparison and regional structures should be enhanced in the future, and then the prospecting model must be verified by exploration engineering. |
