Abstract: The Dongduaoba gold deposit, located in the precious metal metallogenic belt of Middle Tajikistan, is one of four large-sized gold deposits that had been discovered in Qiaolie gold field.This deposit is obviously controlled by regional nappe structure, which has a space-time relationship with Paleozoic shallow metamorphic sedimentary rock series. Pyrite and arsenopyrite serve as the main gold bearing minerals in this deposit. Native goldinclusions are occurred with in metallogenicpyrite and arsenopyrite minerals. Regionally, the basement strata and upper cap have experienced three times of large-scale structural reorganization in Late Paleozoic era, that is, uplift stage, orogenic stage and final period of Late Variscan stage structure (orogeny), which leaded to the current time-space emplacement of this deposit. Carbonous epimetamorphic clastic rock belt and albitization granite porphyry vein are closely related to the origin and spatiotemporal distribution of gold ore body. The genetic types of gold deposits are epimetamorphic clastic rock type and contact metasomatic alteration rock type, which are related with the deformation, metamorphism and reformation of Early Palaeozoic black rock series.
