DangHe Basin In Gansu Province Cu Polymetallic Deposits Ore-forming Geological Conditions Analysis

DangHe basin in gansu province is one of important the metallogenic belt, rich mineral resources, the copper deposit types development are completement, in this area, contain is rich in minerals such as copper, nickel, chromium, gold, lead, zinc, etc. Based on the working area in gansu province 1:50000 mineral prospect survey,found zone cu polymetallic deposits of ore-forming geological conditions, geophysical, geochemical and mineral characteristics and mineral distribution rule is delineated, geophysical and geochemical prospecting anomalies and mineralization favorable location, and carry on comprehensive study, summarizes research district of cu polymetallic deposits prospecting marks and ore-forming regularity.This paper mainly DangHe basin in qilian cu polymetallic deposits comprehensively, geophysical, geochemical and remote-sensing all kinds of data, relying on digital mapping system and RGmap MAPgis technology platform, with typical cu polymetallic deposits in the point to analyze DangHe basin in gansu province dang geological features cu polymetallic deposits.This paper USES the modern regional metallogenic learn and very large copper polymetallic deposits theory thorough research area ore-forming geological background and zone typical mineralization zones and metallogenic environment, metallogenic factors, ore-forming process and ore-forming materials research in deposits, expounds spatial and temporal distribution regularity, looking for cu polymetallic deposits in the prospecting marks, regional metallogenic prediction and resource potential analysis. Article application foundation geology and ore deposit geology theories and relevant technical method in this region, this paper studies the copper, gold metallogenic conditions and prospecting information, deduce the possible existence of ore deposits (orebody) and its basic characteristics. Also cu polymetallic deposits of metallogenic prediction main application geological analogy method, sum up the region known typical copper of polymetallic mineralization geological environment and the ore-controlling factors, as analogy and infer that unknown have ore region the basis of metallogenic possibility.Through analysis of metallogenic geologic background area, the distribution of ore-forming elements proposed the main mineral resources and research, hopeful breakthrough type for main chromium, ShaJin minerals, its wide distribution and enrichment, ore-prospecting endogenous evident, and gold metallogenic prospect, we should strengthen the most significant of endogenous gold. Also look for new MaiJin origin, such as the altered volcanic relevant volcano-dive volcanic hydrothermal type gold deposits, followed by copper, chromium, lead and zinc.
