摘要:Combining geomechanics with geochetnistry, this paper makes a rather systematic study on the stratigraphic division, tectonic evolution and ore genesis of the Bainaimiao ore field and, on such a basis, puts forward some new ideas. It has been emphatically pointed out that, in addition to the prominent E-W structural zone that controls the Cu-Mo deposits, there also exist N-S and NE structures which dominate Pb-Zn and Au mineralizations respectively. The formation of the copper deposit was attributed to the superimposition of three successive stages of mineralization related to volcano-sedimentation and metamorphic and magmatic hydrothermal activities respectively.
