摘要
Based on systematic collection of rock and ore samples in 11 drill holes along No.7 and No.9 exploration lines in the Huogeqi copper-polymetallic ore district of Inner Mongolia,the authors drew contour map of primary halos,established vertical element zoning sequence and made a prediction of concealed ore bodies in the depth.The ore-forming element association of this ore deposit is Cu,Pb and Zn,the front halo is composed of Hg,Sb and Cd,whereas the rear halo comprises W,As and Sn.There exist at least two phases of ore-bearing fluids along No.2 exploration line,and there might exist blind ore bodies in the depth of ZK702,ZK830,ZK726 and ZK817 drill holes.
