Metallogenic Prediction In The Hadamengou-Liubagou Orefield And Its Periphery Of Inner Mongolia Using GIS

Hadamengou gold deposit is early discovered quartz - feldspar vein-type gold deposits.Now ,significant progress was made in geological survey, gold clusters has been formed by a number of small deposits (points) ,Mainly to Hadamengou, including Liubagou, etc.In this paper, creating the three-dimensional digital model of ore by compiling the geological data for showing the geological characteristics of deposits. more intuitive.Includes three aspects.of strata, faulted structure, igneous rocks As the area of the initial source of ore, almost all the gold veins are output in the Ural Group in the third rock group.The magmatic body of Dahuabei and Shadegai are also coarse-grained porphyritic rock of granite, respectively distribut in the mining area north and west.Analysis shows that the output of its veins is closely related in space, and it most likely provides the driving force of hydrothermal activity. The pegmatite veins in this area, diabase intensive areas such as production output is also beneficial to lots veins..Piedmont large faults control the direction of the metallogenic belt as the main mining structure,and derived by en echelon arrangement of the cracks is extremely beneficial to the forming space, especially in the EW The crack that more conducive to the enrichment of ore materials.On the view of macroscopic, the region information for mineral exploration including alteration zones, geophysics, geochemistry and so on.Mineralization in the veins which accompany the formation of two alteration zones that include silicification - K-feldspar alteration and silicification - sericite - chlorite alteration zones is easily identified; And because the process of gold mineralization activity of the chemical elements and the close relationship between silicification, K-feldspar of and the mineralization, the veins tend to be output in the area with abnormally high values in the Au element and low magnetic anomalies .The first. by using data processing and analysis of the powerful features of GIS to analyze types of geoscience data this area. Second, select the corresponding data processing method for comprehensive analysis of the various factors used in layers. in end, conducting a comprehensive analysis base on ARCGIS software to restrict the favorable area for prospecting.According to various geological, geophysical and geochemical prospecting information, it has complete a favorable distribution maps that consist of the forecast region .most of the abnormal area and the known veins overlap in space or near ,and from the other side indicate that the work of this forecast marks of prospecting information used is reasonable,basically includes all the major ore-controlling factors.In addition, it's provide a good target for the next step in the regional exploration work of six the favorable area for prospecting that has a long distance from orefield.
