英文摘要 | The Weizhou Island and the Xieyang Island are twin islands of volcanoes in the Northern Bay. In this paper, volcanic activity on the two islands was analyzed by K-Ar dating of volcanic rocks OSL dating of sandstone xenoliths in the volcanic rocks and C-14 dating of conch by Accelerator Mass Spectrometer respectively. With the geological characteristics of the volcanic rocks, the volcanic activity was divided into two stages, the early stage in the early and middle Pleistocene (1.42Ma similar to 0.49Ma) and the late stage at the end of the late Pleistocene (36ka similar to 33ka). Flood basaltic shield of the early and middle Pleistocene formed the Weizhou Island and Xieyang Island. In the Weizhou Island, lavas from the Henglushan Guogailing shield volcanic center flooded around the island, and formed the shield like shape of the island. Volcanic rocks of the late stage occurred in the tidal zone, and formed typical spherical weathering. In the late Pleistocene, phreatomagmatic eruptions dominated the two islands, with few magmatic eruptions. The phreatomagmatic eruptions formed typical maars and very thick base surge deposits, which almost covered the whole surface of these two islands. It formed the rich characteristics of modern geography after long time of marine abrasion. |
