Abstract: The lamporphyre is Widely distribution in Qinba mountain areas, the agesare onacin Caledomian, Indosinian, yanshanian and Himalayan Most of the auriferous lam porphyre dike presented in palaeozoic and are mainly Devonian and Silurian and their wall rock are essentially repres ented by fine clastic rock. In this paper, the relation between the lamporphyre Char-acteristics and gold mineralization are discussed. It is suggested that structure fracture have played a very im portant part in diagenesis and ore formation. Alteration, assimilation Contamiation and oxidation of dikes enable the gold easy to activate, migrate, and enrich under suitable metallogenlc conditions.
