| Emerald deposits is found for the first time in South Xinjiang, it is produced in the carbonate veins.The emerald color is emerald green, slightly blue, translucent-transparent mineralization conditions, it is better quality. the research on the emerald are so many in domestic and international, but a comparative study is relatively small,Therefore, this paper analysis emerald (beryl) in southern Xinjiang, focusing on the emerald deposits and mineralogical characteristics,And emerald in South Xinjiang study of these two aspects.compared with the emeralds in Yunnan, ColombianOre-forming region is mainly dominated by the volcanic,Therefore, this paper focuses on the hot spring ditch volcanic rocks of the analysis.Metallogenic background, through the rare earth trace elements, major elements, major elements, and other test data analysis, revealing emerald(beryl) mineralization environment in southern Xinjiang.Through the microscope and electron microprobe, SiO2and Al2O3show positive correlation, high level of Cr2O3and MnO in Samples.Rutile deposits show a certain regularity:from the surrounding rock containing veins body, rutile transition in composition,Containing veins of Fe, Al, V, atomic number of Cr and Ti, atomic number showing a significant negative correlation, indicating that they are replaced by rutile Ti.Analysis of Emerald fluid inclusions in southern Xinjiang, mainly through microscopic characteristics, temperature, salinity and other characteristics of fluid inclusions in contrast, Fluid inclusions are mainly two types:type A, two-phase salt aqueous inclusions; type B, three-phase phase brine inclusions (including sub-fossil).compared with the other two places emerald Characteristics of fluid inclusions in these areas, Analyze the physical and chemical conditions in the formation of the study area, emerald (beryl),Eventually come to the genesis of type belonging to the carbonate-type high temperature gas-hydrothermal deposits. |
