Abstract
The morphological and petrologico-geochemical features, and the time-s pace evolution history of Mesozoic dyke-swarms in Da Hinggan Mts. are studied to explore the polytopism and polytrope of the driving forces for deformation of the continental lithosphere. It is found that two d ynamic mechanisms were coupled in the deformation of the upper lithosp here when upwelling and intrusion of the mantle-derived magma occurred .
