| Since the discovery of the gold force in the 1980 s,the cumulative amount of gold resources in the gold ore field in Haddamengou has been more than 100 tons,and it has been the focus of attention and research at home and abroad.In order to further guide the next exploration work of the mine area,this paper systematically studies the characteristics of the 313 pulse structure superimposed halo of the Hadamungou gold mine,and obtains the following understanding:(1)Mo,Ag,W,Bi,As,Sb,Hg,Cu,Pb are elements closely related to Au mineralization,which have been activated and migrated in the process of tectono-mineralization and enriched in favorable sites.(2)Au,Mo,Ag,and Sn are obviously multi-peak distributions,reflecting the multiple stages of mineralization and their strong enrichment tendency during the mineralization process.(3)Au has a relatively significant positive correlation with the three elements Cu,Pb,and Fe,so these three elements can be used as good indicator elements of gold mineralization.(4)Through R-type cluster analysis,the elements can be divided into three groups,of which Ti,V,Fe,Mn,Cr,Ni,Co,Sn,W are a group,and Cu,Pb,Au,Bi,Mo are a group.,The final As,Sb,and Hg are a group.(5)Au belongs to F2(Au,Sn,W,Bi,Cu,Pb),F3(Au,Mo)and F4(Au,Bi)factors,respectively,It is indicated that Au may be formed in the polymetallic sulphide stage and superimposed on the quartz-Molybdenum stage.(6)By studying the structural superimposed halo characteristics of vein 313,it is considered that although the shallow position of the orebody in the western segment of vein 313 has been denuded to a certain extent,it may not have denuded the main rich orebody.I It is predicted that there is a blind orebody between 200 and 500 m elevation in the range of 100 m on both sides of the 36-line exploration line;within the range of 100 m on both sides of the exploration line 4,there is a second blind orebody between 700 and 1000m elevation. |
