上庄金矿区地处焦家断裂带北段,矿区内分布有焦家断裂、东庄子断裂、侯家断裂及望儿山断裂等,主要出露岩石为郭家岭型花岗闪长岩和玲珑型花岗岩,第四系覆盖广泛。本次找矿预测的目标是地表下1000~2000 m深度范围的隐伏金矿体,根据测区岩石露头少及探测深度大的条件和要求,化探方法采用了次生晕法与土壤吸附烃法,物探采用了大地电磁法( MT法)。完成次生晕法与土壤吸附烃法测量约9 km2,结合多元统计分析,厘定测区化探异常找矿标志为次生晕法Au-Ag-Hg元素组合异常及因子得分Y(i,5)得分异常,土壤吸附烃异常可做为辅助性找矿标志。完成11条测线共460个测点大地电磁测深,探测深度2000 m。根据地、物、化、遥多元异常信息,圈定找矿靶位3处。其中,A靶位经钻探工程首先验证,发现了新的隐伏矿体并探获金内蕴经济资源量(333)储量6 t。

Shangzhuang gold district was located in northern Jiaojia fault zone .There was Jiaojia fault ,Dongzhuan-gzi fault,Houjia fault and Wang'ershan fault in the mining area .The main exposed rocks were Guojialing type grano-diorite and Linglong granite with wide Quaternary cover area .The concealed gold orebodies in depth of 1 000-2 000 m below the surface were the prospecting targets .Considering the lack of outcrops and the great probing depth ,secondary halo method and soil adsorption hydrocarbon method were chosen as the geochemical prospecting methods ,while mag-netotelluric sounding ( MT) was chosen as the geophysical prospecting method .Measurement of about 9 km2 by sec-ondary halo and soil adsorption hydrocarbon was completed .Based on multivariate statistical analysis ,Au-Ag-Hg ele-ments assemblage anomalies and factor score Y(i,5) anomaly were determined as the main secondary halo marks for deep orebodies prediction ,and the soil adsorption hydrocarbon anomaly could be used as auxiliary for prospecting ore-bodies.Measurement consisting of 11 lines and 460 measuring points by magnetotelluric sounding was completed ,with measuring depth of 2000 m.3 ore-prospecting targets were delineated according to data gained from the multiple anom-aly information analysis of geological ,geophysical ,geochemical and remote sensing prospecting .Among them ,target A was validated by drilling ,and with it new blind orebodies were found and gold intrinsic economic resources of 6 tons (333) were obtained.
