Xinjiang Hami The Redstone Copper Structure Geochemical Characteristics And Metallogenic Prediction

Hongshi copper in recent years non-ferrous mineral exploration Geological Survey and found a large copper (zinc gold) exploration and development base. Mine is located in the Turpan-Hami Basin, Xinjiang, the southern margin Dananhu-Palaeozoic island arc first spring with the Soviet Union's northern section, forming an advantageous location, rich in mineral resources.Structure and mineralization of the study area very closely, has invested a lot in the early physical and chemical measurements and deep drilling, hole exploration project revealed, local volcanic lithology, structure, mineralization characteristics of complex-forming regularity is not yet clear, The new exploration breakthrough unknown. Paper aims to construct the space observation ore deposits in analyzing the geology through field research, indoor test analysis, a comprehensive analysis of mathematical statistics and other methods to study the distribution of geochemical anomalies mining structure to summarize the spatial distribution of regularity, for the next forecast to provide a favorable basis for prospecting.Structural studies:the volcanic rocks in this area is broadly divided into three five-phase cycle, identify the two ancient volcanic eruption centers; the structure of the fracture surface were systematically identified, from the direction of the faults are divided into nearly north-south and east-west, NW, NE and NEE to five groups, and its structure is divided into three periods, of which nearly north-south and east-west trending faults control the volcanic area of the intersection of institutions, deposits (above), the mineralization The distribution of alteration zones; crack construct period statistics show that hydrothermal mineralization to the north-east to nearly north-south principal stress was tension to fracture, which will help increase mineral liquid filling, while the latter part of the NNE-trending fault is the most important broken ore broken. Construction Geochemistry:Try using XRF geochemical data obtained and achieved good results; or near the surface of the original halo Redstone mine statistical analysis showed that Cu, As, Sb, Bi, Zn and other elements of high geochemical background, local have enriched the possibility of mineralization; outbreak phase, such as tuff, volcanic breccia, volcanic rocks such as overflow andesite, dacite favorable ore-forming element enrichment, overflow with volcanic rhyolite and rhyolite porphyry with channel phase prospecting conditions; the middle of breaking rocks in different factor analysis showed that the enrichment of ore-forming elements by NS-trending sheets (twist) and the EW rupture pressure (torsion) fracture of the composite control, often enriched at the junction of the two most obvious; mining shallow to deep tectonic geochemical anomalies from north to south and east to west spread, sink, indicating concealed deposits south and east lateral deep V there may be many hidden ore bodies.Finally, the use of analogy proposed basaltic Meiling ore block-andesite dome area and the southeast section of the deep Hongshi copper quarry vision for the exploration section.
