摘　　要：通过在辽宁宽甸大西岔一带硼矿成矿预测区开展物化探勘查工作,结合地质成矿情况,总结了本地区隐伏硼矿(化)体的物化异常特征:地球化学土壤测量显示为B-Mg组合异常浓集中心,激电中梯测量表现相对低阻低极化率异常,可控源音频大地电测深反演电阻率为低阻异常。建立了本区沉积型硼矿的地物化找矿模式,提高了找矿效率。Based on the geophysical and geochemical exploration work in the boron ore-forming prediction area of Daxicha,Kuandian County of Liaoning Province,with the combination of the geological metallogenic condition,the characteristics of geophysical and geochemical anomalies of the hidden boron ore-forming bodies in this area are summarized.The geochemical soil survey shows the anomaly concentration of B and Mg.The IP electric intermediate ladder measurement shows a relatively low resistance and low polarizability anomaly,and the controllable source audio geodetic sounding inversion resistivity is low resistance anomaly.The geological,geophysical and geochemical prospecting model of sedimentary boron deposit is established in this area.It improves the prospecting efficiency.
