Abstract
Fluorite is a strategic mineral in China and an advantageous mineral in Inner Mongolia Autonomous Region.The Xilimiao Sumochagan Aobao area is one of the important fluorite deposit gathering areas in China.Fluorite deposits have both sedimentary alteration and single vein types.With major breakthroughs in the exploration of fluorite deposits in Xilimiao,Adeghashantu,Sumochagan Aobao,Aobaotu,Aobaoshan and other areas in the past two years,the mineral resources identified in this area have exceeded 30 million tons,becoming a hot soil for fluorite exploration in China's new round of mineral exploration strategies.In depth research and summary of its mineralization laws and deposit genesis are of great significance for fluorite exploration in the Xilimiao Sumochagan Aobao area and other regions of the country.Based on field investigations and typical deposit studies,this article further summarizes the types,spatial distribution patterns,diagenetic and ore-forming ages,rare earth element compositions,ore-forming fluid characteristics,and ore-forming element sources of fluorite deposits in the Xilimiao Sumochagan Aobao area.It is believed that the fluorite deposits in this area belong to typical hydrothermal genesis,and the surrounding rocks of a single vein shaped fluorite deposit not only play a role in ore bearing,but also provide important material sources for mineralization.The summarized characteristics of surrounding rock strata,magmatic rocks,and spatiotemporal distribution patterns are important references for the search for fluorite deposits and mineral deposit studies in other regions.关键词
