甘肃省北山地区处于中亚型造山带南缘,是东天山成矿带的组成部分。近年来多个资源勘查项目和资源潜力评价项目在北山地区同时启动,找矿勘查成效显著。但是综合研究相对滞后,成矿带内岩体的成岩过程,成岩时代与构造背景等尚不清楚,制约着成矿预测工作的开展。大山头杂岩体与近年来勘查发现的黑山大型铜镍矿床处于同一构造成矿带,距黑山铜镍矿床大约西50km,是否与黑山含矿岩体为同一构造岩浆事件的产物,其含矿以及成岩构造背景如何?等一系列科学问题亟待解决。本次研究获得部分地球化学研究成果供研究者参考。
The Beishan area of Gansu Province is located in the southern margin of the Central Asian orogenic belt and is an integral part of the East Tianshan metallogenic belt. In recent years, a number of resource exploration projects and resource potential assessment project started in Beishan at the same time, and the prospecting results were remarkable. However, due to the relative lag in comprehensive study, the diagenesis, diagenesis and tectonic setting of the rock mass in the metallogenic belt are not clear, which restricts the development of metallogenic prediction. The Dashatou complex is located in the same tectonic metallogenic belt with the large Montenegro copper-nickel deposit discovered in recent years. It is about 50 km west of the Montenegro copper-nickel deposit and is the product of the same tectonic magmatism with the Montenegro ore-bearing rock mass. As well as diagenetic tectonic background? A series of scientific problems to be solved. This research obtains some geochemical research results for researchers’ reference.
