A PRELIMINARY STUDY ON THE EMPLACEMENT MECHANISM AND MAGMA DYNAMICS OF THE GRANITE IN ZHUANGHE AREA, LIAONING PROVINCE: A Case Study of the Guangmingshan Composite Granite Body

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.
