武功山热穹隆，以加里东造山期复式花岗岩为中心，南华-寒武系遭受区域变质形成变质矿物分带，环绕岩体分布，中生代以来伸展形成的韧脆性断裂系统构成外环，共同组合形成穹窿状构造。造山早期（463.2±2.3 Ma），初始重熔岩浆与深埋变质围岩交代形成原地型英云闪长质“混染岩浆”，岩浆上升中，硅铝质组分加入使酸度增加，过渡为花岗闪长质岩浆，并产生岩体边缘混合岩。造山晚期（409.4±5.1 Ma）演化为正常花岗岩，构成同源岩浆成分演化序列，并伴有明显构造应力变形。中生代伸展-岩浆作用的复合叠加，进一步强化了热穹窿的构造背景，大致在早白垩世末基本定型。

Wugong Mountain thermal dome, which took the Caledonian composite granite as the center, Nanhua-Cambrian System formed metamorphic mineral zoning by regional metamorphism, and distributed surrounding rock mass, ductile-brittle fracture system formed outer rim since Mesozoic, which combined to form the domal structure. In the orogenic forepart(463.2±2.3Ma), the initial remelted magma and deep metamorphic rock formed tonalitic hybrid magma in situ, with the ascent of magma, silicon and aluminum components increases the acidity, transits to granodiorite magma, and generates mixed rock in rock mass edge. In the late orogenic stage(409.4±5.1Ma), evolved into normal granite, constituted the homologous magma composition evolution sequence, and accompanied obvious tectonic stress deformation. Compound superposition of extend magmatic action in Mesozoic, further strengthen the tectonic background of thermal dome, and ifxed basic shape roughly at the end of Early Cretaceous.
