ORIGIN OF THE LINGSHAN ISLAND AND GEOTECTONIC SIGNIFICANCE

The Lingshan Island was originally formed when the North China plate and the Yangtze plate collided. In the later stage, it has been under the influence of interaction between the Pacific plate and Philippine plate and their movement against the Eurasia. Based on the sedimentary features and zircon ages, from the viewpoint of geodynamics, it is revealed that the Lingshan Island was formed by multiple dynamic processes including tectonism and magmatism (both volcanism and intrusion). The results are helpful to the understanding of formation, and sedimentation as well as hydrocarbon generation and accumulation in the adjacent basins.
