天柱县大河边地区重晶石矿层厚度分布特征研究

Study on Thickness Distribution Characteristics of Barite Deposit in Dahebian Area of Tianzhu County

大河边重晶石矿位于贵州省天柱县,其成因类型是海底喷流沉积成矿。但是,有关重晶石矿分布的分析较少,尤其是厚度等值线方面,无法支撑喷流来源中心或通道的研究。本文根据现有探槽和钻孔资料,结合相关勘探线剖面研究,对重晶石矿层进行厚度等值线分析。综合分析认为,天柱县大河边地区重晶石矿的主要控制因素为坪地断层(F_(1)),即F_(1)断层可能就是成矿物质喷流来源的主要通道,其两侧均应具较好的找矿潜力。

The Dahebian barite deposit is located in Tianzhu County,Guizhou Province,and its genetic type is submarine jet sedimentary mineralization.However,there is limited analysis on the distribution of barite deposit,especially in terms of thickness contour lines,which cannot support the study of jet source centers or channels.Based on existing trench and drilling data,combined with relevant exploration line profile research,this paper conducts thickness contour analysis of the barite deposit.Based on comprehensive analysis,it is believed that the main controlling factor for the barite deposit in the Dahebian area of Tianzhu County is the Pingdi Fault(F_1),which may be the main channel for the source of ore-forming material jet flow,and both sides of the F_1 Fault should have good prospecting potential.
