The Mesozoic magmatic activities and tectonic movements are intensive in Western Liaoning region, with broadly distributed intrusive rocks. The rock bodies, occurring in different forms, with complex types, are concentrated in four NNE- or NE-trending belts. The intrusions are divided into three periods, i.e. Indosinian, Early Yanshanian and Late Yanshanian. In each period, the magma evolved from intermediate-basic to acidic. The distributions of magmatic activities are controlled by the E-W, NE and NNE structural systems. The Mesozoic magmatic cycles are closely related to the multi- stage and multi-phase of crustal movement.
