Causes Of Metallogenic Regularity And Metallogenic In The Shikebutai Iron Deposit Of Xin Jiang West Tianshan Mountains

Iron mine is one of the many beneficial minerals in the Xinjiang Uygur Autonomous Region, not only the type of variety, a large development area, the most important is that a lot of the number of rich iron ore deposits, a high proportion. It has been found and proven reserves of verification was ranked among the five provinces in the northwest up to second place.One of the twenty-six major iron ore metallogenic belt of Xinjiang Western Tianshan Mountains metallogenic belt, located in the Western Tianshan orogenic belt. Now Awulale iron copper mineralization in western Tianshan Mountains was determined as one of the replacing base of national ten big important metallic mineral resources. Shikebutai iron deposit in west of the Awulale metallogenic belt in western Tianshan Mountains, metallogenic conditions are relatively good, the genetic type of very typical, the Awulale metallogenic belt is very representative of the significance iron ore deposit.Based on the Shikebutai iron deposit as the research goal of analysis, with the mineral deposit geology, structural geology, petrology and geochemistry, mineralogy, isotope chronology as the theoretical basis, by summarizing the characteristics of ore deposit geology, geochemical, geophysical and geochemical aspects of the systematic study on the Shikebutai iron deposit, for the analysis of metallogenic conditions, metallogenic mode is established,summarize the prospecting criteria,the final determination of the genesis of the deposit.Research shows that the metallogenic regularity: LA-ICPMS zircon U-Pb dating results show that in the study area the volcano rock at the age of 301 to 313 Ma this range, it can explain it in the early Late Carboniferous volcanic output of shikebutai iron deposit. Iron ore deposits in the ore is produced in the sedimentary period of the volcano:In late volcanic activity, the vast majority of volcanic material ejected gas and liquid, the ejecta contains a huge number of ore-forming elements and volatile matter, falling to the sea, the sea in a reducing environment with water inside the element combination, Composed of pyrite(copper) ore. Found to produce or occurrence area of mineralized alteration and ore body in the study, there is no contact, whether the variable effects of bottom ore as no alteration in the rock. In terms of material sources REE patterns and its characteristic parameters there are certain rules to be found, discovered Eu anomaly is more prominent, and there is enriched in light rare earths and heavy rare earths weak losses, thus a good description of the Shikebutai iron deposit the formation of mineral matter from the upper mantle sources may also be from the deep crust. From the composition of fluid inclusions analysis can be seen, the seabed exhalative hydrothermal sedimentary mineralization of the influence in this deposit. Hydrogen and oxygen isotope characteristics of ore-forming fluid can be seen in the shikebutai iron ore deposit with seawater and mainly from magmatic water. Through the analysis of two adjacent analogy with shikebutai iron ore deposits in the surrounding area, summed up the research for this volcano sedimentary type iron ore prospecting marks. Through the analysis of a series of summary, the post production work more purposeful. Exploration for future deployment first warm-up.The shikebutai iron ore deposit genesis: according to the physical and chemical conditions of mineralization, magmatite geochemical characteristics and combined with regional geological data analysis we can see that the shikebutai iron ore deposit origin types should be marine volcano sedimentary type, hydrothermal. The ore deposit should be the volcano sedimentary type.Research on the causes of metallogenic regularity and deposits for prospecting and forecasting times deeper into the premise. By studying shikebutai typical deposit, the larger will be the rich iron ore deposits awulale metallogenic belt in western Tianshan Mountains in basic geological research questions and improve the level of mineral deposit exploration and research, prospecting for further practice and expand prospecting potential theoretical and practical significance.
