摘　　要：通过1/5000岩石地球化学测量,在矿区内圈定以Au元素为主的综合异常7处,均处于华力西晚期钾长花岗岩体与石炭系火山岩的内、外接触带及北西向和北东向两组断裂破碎带上,沿破碎带岩石破碎,蚀变强烈,异常与区内已知金矿体和含金石英脉及构造蚀变岩中的矿化所引起,多数属于矿致异常,显示出岩石地球化学测量在该区域具有良好的找矿潜力,后期应加强综合异常区的地球物理方法研究,为深部探矿工程布设提供依据。Through rock geochemical survey,1/5000 is given priority to with Au element is delineated in the mining area comprehensive anomaly 7,in the late variscan potassium long granite rock mass and the carboniferous volcanic rocks in the inside and outside contact zone and north west and north east to two groups of fractured belt,along the fracture zone of rock breakage and alteration,abnormal and known gold ore bodies and contain in the mineralization of gold quartz vein and structural alteration rock caused,most belong to mineralization anomalies,shows that rock geochemical survey in the area has a good prospecting potential,the late should strengthen the comprehensive anomalies of geophysical methods and research,provide the basis for deep prospecting engineering layout.
