摘要
The tectonic movements of Pingtan-Dongshan fold belt and Changleh-Zhao’an fault zone occurred in Late Jurassic. Due to the influence of tectonic movement and magmatic activities, formed a series of islands off the coast of Southeast China including the Matsu Islands. The results show that the Matsu Islands have 9 marine terraces, with heights of 0~10 m, 20~38 m, 40~56 m, 58~78 m, 80~97 m, 100~128 m, 142~160 m,172~182 m and 238~248 m. Based on the relationship of Late Pleistocene marine terraces sequence and uplift rate base map, the authors have estimated formation age of various marine terraces, i.e., 6 ka B.P.,46 ka B.P., 55 ka B.P., 76 ka B.P., 79 ka B.P., 94 ka B.P., 105 ka B.P., 119 ka B.P. and 175 ka B.P.. The terraces formed in Pleistocene except the first step in Pliocene.
