摘要
以中亚环巴尔喀什成矿带为典型研究区域,结合地质矿产、地球物理、地球化学和信息科学等信息数据及野外调查成果,以斑岩铜矿为主要矿床类型,以中比例尺对新疆及邻区的跨境巴尔喀什-准噶尔成矿带的含矿潜力进行整体研究.分析中亚大型矿集区成矿地质条件,总结研究区斑岩铜矿成矿规律,建立多元信息综合识别标志及矿床模型.结合空间数据分析技术,以ArcGIS为平台,建立中亚跨境成矿带主、客观模型整合的大型矿集区预测系统,得出中亚成矿带矿集区预测分布图,通过理论研究到技术方法的实现,为境内寻找大型矿集区奠定基础.
This paper briefly Study the tectonic enmronment,geological characteristics and distribution of the large metallogenic ore belt in Central Asia.Taking metallogenic districts of Baerkashi as typical study area and combining multi temporal remote sensing data and field work results, With the constantly changing knowledge of the division of metallogenic belts and types and characteristics of metallogenic formations in adjacent regions of Xinjiang, the authors emphasize that in comparing the geology and mineral resources in Xinjiang with those in its adjacent regions it is necessary to gain knowledge of their research histories and seek to make such comparison based on ascertaining basic ore- controlling elements. In addition, in Central Asia mineralization related to Early Paleozoic continental crustal accretion is quite important, All these belong to the characteristics of the Central Asian metallogenic megaprovince and must be fully considered in the comparative study. And mineralization element association show certain zonation from intrusive bodies to wallrocks. On the base of discussion of the mineralization regularity and mechanism in the central area is proposed.
