Take the site prediction of three gold lode deposits as examples,the authors try to show the key role of major ore constraints in site prediction-strategic directing.

The Au metalizing types,and ore-control factors in the Liuhe area ,Jilin Province and the direction for ore prospecting;

In order to reveal the metallogenetic regularity of multi-metal and ore-control factors in this area, metallogenetic conditions have been studied from such factors as the regional geological setting and geochemistry, ore-beating formation and metallogenetic structures, it is supposed that Guanlinggeng Pb-Zn deposit is a magamatic hydrothermal deposit of medium-low temperatur.

The regional geologic setting and geologic characteristics of the gold mineralization in the Toudaogou area, Ankou Town, Liuhe, are analyzed, making the study of the regional geophysical field, and the geochemical field division, meanwhile,the main ore-control factors were preliminarily summed up in the study area.
