Perdu rhyolite porphyry of Yanshanian period is mainly located in volcanic rocks of Zhangjiakou of the Upper Jurassic series in Guyuan volcanic basin cover. Perdu rhyolite porphyry is controlled by faulting and volcanic structure of late Yanshan period in the spatial distribution, close relations with uranium-molybdenum mineralization, which mainly occurred in contact of perdu rhyolite porphyry and its top crypto explosive breccia. Perdu rhyolite porphyry intruded into surrounding rock in vein, stock and dyke form etc. Rock geochemistry study showed that it is peraluminous calcium alkaline rock series with characteristics of high silicon rich alkali, the diagenesis tectonic environment is pull-spread one of late Yanshan period, the genetic types is the crust lava crystallization.
