英文摘要	The Bamao volcanic complex is characterized by wide ranges in the composition including basaltic, trachy basaltic, trachyte andesitic, trachy dacitic, rhyodacitic, rhyolitic and high-silica rhyolitic rocks. They did not evolved from single parental magma, and also did not extrude from single magma chamber, as came from poly-types magma chamber, had undergone the processes of complex evolution, being composite evolution of poly-mechanics in open system. The basic element of bimodal volcanism in early stage was formed by partical melt of upper mantle, while the acid element was the product of crust material immiscibility melt. The trachy dacitic rocks which are composed of the major part of the complex were formed by mixing of basaltic magma and rhyodacitic magma in high level major chamber. Trachyte andesitic magma was formed from basaltic magma by crystallization differentiation in deep magma chamber. The rhyodacitic dome and high-silica rhyolite-porphyry dike extrusion and intrusion in late stage represent major composition of high level proximate grade and its upper silica cap.
