西北主要成矿带地质矿产调查工程进展

为支撑找矿突破战略行动,服务国家矿产资源后备基地建设,在中国地质调查局计划-工程-项目新的总体布局下,西安地质调查中心联合中国地质科学院矿产资源研究所、有色金属矿产地质调查中心、国土资源实物地质资料中心、郑州矿产资源综合利用研究所和30多家地勘单位等,开展了西北主要成矿带地质矿产调查.在已有成果的基础上,通过近2年的工作,新发现矿(化)点200余处,圈定找矿靶区70余处,一批找矿成果持续获得地方基金支持,部分矿权已成功招牌挂,有效地带动了社会资金的投入,深化了铜镍、金、石墨、硬岩型铀矿等成矿规律的认识,促进了找矿突破,支撑了大型矿产资源基地建设,创新了造山带填图、戈壁荒漠区地质填图以及工程-项目成果的集成与编图技术,实现了与地方资金投入的统一;同时支撑了科技条件平台建设与人才培养,基本实现了大项目机制.该文围绕"西北主要成矿带地质矿产调查工程"的目标任务,阐述了工程的技术路线和取得的主要成果,并对未来的工作进行了展望.

Progresses of geological and mineral survey project in main metallogenic belts of Northwest China

In order to support the strategic action of prospecting breakthrough and serve reserve base construction of national mineral resources, under the new overall layout of China Geological Survey for 3-level project management systems, Xi''an Geological Survey Center carried out a geological and mineral survey in the main metallogenic belts of Northwest China together with more than 30 institutions including Institute of Mineral Resources(Chinese Academy of Geological Sciences), China Non-Ferrous Metals Resource Geological Survey, the Cores and Samples Center of Land and Resources, and Zhengzhou Institute of Mineral Resources Multipurpose Utilization. Based on the existing achievements, more than 200 mines and mineralized spots were discovered, and more than 70 prospecting target areas were delineated. In addition, batches of prospecting achievements are supported by local funds continually and some of them have been auctioned successfully in the last two years. These effectively attracted some social capital investment, promoted the prospecting breakthrough, deepened the understanding of metallogenic regularity of copper, nickel, gold, graphite and hard rock type uranium deposits, and also supported the construction of large mineral resource bases. We innovated some new technologies such as mapping in orogenic belts and Gobi desert areas, the integration of project achievements, and mapping technology, and realized the coordination between national funds and local capital investment. The platform construction of science and technology and talents cultivation was supported in the meanwhile, and the large project mechanism was realized. This paper focused on the geological and mineral survey of the main metallogenic belts in Northwest China, and described the technical route, main achievements of the project and the future work.
