Features of Structural Superimposed Halos in Sanshandao-Xinli-Cangshang Gold Deposits,Shandong Province

Sanshandao-Xinli-Cangshang gold deposit is the important part of Zhaoye gold deposit.Its surface and shallow resources would dry up constantly,as more than 10 years of mining.It is particularly important to carry out the deep and periphery prospecting work using advanced technology in mining.This study adopted a new method of structural superimposed halos to predict the blind ore-body,established the structural superimposed halo model,and emphatically analysis the characteristics of structural superimposed halo's key elements in the different middle ore deposit.Results of blind ore prediction show that 28 target areas have been preliminarily put forward in Sanshandao gold deposit,and the depth of main orebody predicts metal quantity of 35 234 kg;14 target areas have been preliminarily put forward in Xinli-Cangshang gold deposit,and the depth of main orebody predicts metal quantity of 52 189 kg,better prospecting effect was obtained.
