Abstract Based on the theory of magma dynamics, the driving force, ascending channel and its minimum critical width for the magma emplacement of Guangmingshan composite granite body are discussed. It is suggested that the rock body was formed as a result of the granitic magma invading upwards in dikes with the minimum critical width of ascending channels, which were provided by deep faults, and emplaced in the shallow crust with expanding of the dikes.

Key words： granite emplacement mechanism magma dynamics Guangmingshan composite granite body Liaoning Province
