Abstract: Petrologic, geochemical, structural, geological and thermochronologic data show that Xi Xiongwen intrusion belongs to the remelting synuplift-adamallite, which stemmed from its metamorphic-country rocks. And the inclosed structure surrounding this intrusion is regarded as the thermodynamic dome that results from uplift of western Dabie block and magmatic diapirism associated with it. The process of forming and emplacement for the intrusion provides useful and indispensable constraints on the shaping-process of the thermodynamic dome. The study suggests that the equal-mass remelting process leads to volumetric expansion which is 1.2 times as much as the volume of metamorphic-country rocks, that the slowly cooling process(4.4℃/Ma)and emplacement of the intrusion that coordinate country rocks force the thermodynamic dome to shape under the surface of 15.2 km in 161.5 Ma, and that the minimum height of the dome is about 5 km. As a result, such information as the nature of the remelting process, the value of volumetric expansion, the intrusive velocity, the coling process, the crystallization depth and the emplacement-age etc. of the intrusion can help understand further or depict quantitatively the shaping-process of western Dabie thermodynamic dome which is a typical structure during Dabie-block slowly uplifting in Mesozoic era.
