On the basis of the survey and study of structure in the Yongping copper orefield, this paper preliminarily discusses the tectono--geochemistry of the mainrock-and ore--controlling structures--the F_1 fault and the Houjia-Songshan over-turned anticline fold in the ore field as well as the geochemistry of metallo-genic structures, i. e. the influence of tectonic stresses on the migration and enri-chment of ore--bearing solutions and ore--forming material. At last, the metallo-genic model of tectono--geochemistry in the Yongping copper ore field is also pro-posed.
