[Abstract]:The research topic of this paper comes from the Sino-Myanmar cooperation project "Geological Prospecting of Jingmen Gold Mine area in the fourth Special Zone of Myanmar", which was undertaken by Professor he Mingyou. Through this study, the geochemical characteristics of gold and its closely related elements are discussed, and the ore-prospecting targets are delineated. It provides data support and scientific basis for the qualitative evaluation of prospecting potential and prospecting prospect in this area. Therefore, this thesis has important scientific research significance and practical application value. This paper chooses the gold ore area as the research object, closely combines the project research task, emphatically studies the element geochemistry characteristic of the gold deposit area. The data were collected by 1: 5000 soil geochemistry measurement method and rock geochemistry measurement method respectively. According to the data obtained by X-ray fluorescence instrument and atomic absorption spectrometry, the data processing and correlation analysis were carried out by using SPSS and Sufer software. On this basis, multi-element geochemical anomalies and prospecting targets are delineated. The research contents include: regional geological background, deposit geological structure, metallogenic geological conditions, prospecting and prediction. Through the above research, we can get the following understanding: 1. The geochemistry survey of soil can be used as an important and effective prospecting method in this area. By using the method of soil geochemistry survey, the prospecting target area can be quickly reduced and the geological prospecting can be provided more directly. The results of factor analysis show that the contribution rate of factor 1 is 46.346, which represents magmatic information, especially the information of iron group element migration, and factor 2 (AsPbPbPbBHG) contribution rate is 20.372.The contribution rate of factor 1 represents the information of medium and low temperature hydrothermal solution, and it may also be the information of fault, and it is also possible that the contribution rate of factor 2 is 20.372, and that the contribution rate of factor 2 is 20.372.The contribution rate of factor 1 is 46.346mg, and the contribution rate of factor 2 is 20.372.The contribution rate of factor 2 is 20.372. The contribution rate of factor 3 (SB ~ (2 +) is 10.388, which represents the information of polymetallic mineralization such as tin (or Sn-rich granite), and factor 4 (Ca) contribution rate of (Ca) is 6.42828), which represents the information of polymetallic mineralization such as WGZn-Cu, and has experienced calcification geological process in the later stage. The best indicator element for gold prospecting in soil geochemistry in this area is the indicating orebody of As-PbPbPbBiHgPbBiHgTiTi-BaCoCoFE-NiCr-Cr-Mn orebody. Three anomalous areas can be found from the single element anomaly map and the comprehensive element anomaly map obtained from the data processing of soil survey by sufer software. The anomalous field is the most promising area because of its strong intensity and large scale. It should be regarded as the key exploration area, and the three most promising prospecting target area .4 should be delineated accordingly. The rock survey data show that the Au-Ag content is the highest in silicified rocks. The results of factor analysis show that the association correlation of Au-As-Bi-Ag-Bi-ZZN Cu-Sb-Pb-Bi assemblage is very good. The results are as follows: 1. Using soil and rock element analysis data, cluster analysis, factor analysis and cumulative frequency method were used to process the data to extract the abnormal information of au element and delineate the gold anomaly field. It is also pointed out that as HgPb can be used as an effective prospecting marker for gold 2. According to the anomalous characteristics of element assemblage, metallogenic geological background and ore-controlling factors, three main ore-prospecting targets are delineated. The direction of prospecting in the area in the future is determined.
