Micrograined inclusions in Qingyang rock body are both similar to and obviously different from host rocks in such aspects as petrology, mineralogy and geochemistry. The similarity shows their affinity, and the differences reflect the attributes of partial melting relicts of inclusions. There also exist some differences in magmatic dynamic characteristics between Qingyang rock body and its micrograined inclusions, which reveals the state of movement of inclusions in the process of magmatic emplacement. The characteristics of micrograined inclusions provide significant information for the genesis of magmatic rock.
