[en] There are three series of magmatic rock with different characteristics in Tianmujian basin. The first series is formed by Fangjian Group's dacite tuff, dacite breccia tuff lava, andesite breccia lava-gabbro diorite porphyrite, controlled by basement fault and volcanic structure. It is formed in compressional geologic setting. The second series compose of Shouchang Group's two kind rhyolite, named I and II-rhyolite, granophyre-monzonite, quartz syenite, controlled by east-north deep fault. It is formed in transitional environment from compression to extension. The third series composed of peridotite, ankaramite and diabase, controlled by basement deep mega fault. It is formed in the extensional geologic setting
