Based on the pressure curve experiment, the physical characteristic of ore-bearing rocks of the Luoba lead-zinc deposit in the Qinling Xicheng deposit field shows small porosity, low permeability and bad link ostiole in the ore-bearing rocks series. The feature indicates that the physical characteristic of ore bearing is unfavorable for forming the Luoba lead-zinc deposit.

In this his dissertation, the field geological work and modern analysis were finished on the Qulong ore-bearing porphyries. The mineralization chronology, petrology, element and isotopic geochemistry were studied on the porphyries. This dissertation also compare this work in Qulong ore-bearing porphyries with other ore-bearing porphyries in Gangdese belt, in order to probe into dynamical background and mineralization features of the ore belts in the condition of India-Eurasia collision.
