Using the biogeochemical method, the authors made regional botanogeochemical experimental researches in the Gongpoquan copper ore district of Beishan area. It is shown that some desert plants have good ore-indicating significance to some elements in their living environments, that the plants of that area demonstrate especially strong correlation with copper in Quaternary coarse fragments within ravines and valleys, and that their regional distribution also assumes some similarity. In some districts, plants are comparable with coarse fragments in contents of such elements as Zn, As and Co. It is also concluded that in vegetation survey of this area, Cu, Zn, Ag and Pb have ore-prospecting indicator significance, whereas Mo, As and Co have no special tracing significance for copper deposits.
