关于中国西部龙首山、祁连山成矿区(带)进一步找矿问题的思考

进入21世纪以来，我国许多矿山都面临着后备资源危机问题，西部地区甘肃境内的龙首山、祁连山成矿区(带)里的矿山也不例外。从“成矿系统”的观念出发，深入分析了区域成矿构造背景，认为区内存在华北古陆西南和柴达木-中祁连北部两种大陆边缘；提出应利用非传统矿产理念进行新一轮矿产勘查，在龙首山、祁连山成矿区(带)不仅要加强传统矿种的勘查，也要注意新类型矿产的开发，同时注意环境保护；最后，还强调矿产资源的勘查和开发工作离不开既有较高理论水平又具有丰富勘查经验的高素质勘查人才，也离不开强有力的资金保证。

PONDERING UPON THE PROBLEM OF FURTHER EXPLORATION IN THE LONGSHOUSHAN-QILIANSHAN ORE BELT, WESTERN CHINA

Many mines in China have been confronting with crisis of reserved resources since the 21st century. The mines, which situated in the Longshoushan-Qilianshan ore belt in Gansu province can not run away from such a fate. From the idea of metallogenic systems, We analyzed regional metallogenic tectonic settings of the Longshoushan-Qilianshan ore belt, and considered that there are two continental margins of Southwestern North-China paleocontinent and Northern Qitam-Mid-Qilianshan plate. We think it very necessary to carry out a new circle of mineral exploration under the guidance of nontraditional-mineral-resources-theory. In the Longshoushan- Qilianshan ore belt, we should not only strengthen the exploration of traditional minerals but also pay more attention to new type of mineral resources. At the same time environment protection should also be emphasized. Minerals exploration is based on talents who have advanced theory, abundant exploration experiences and large amount of capitals.
