Identification of Early Paleozoic Andesite in Northwestern Hainan Island and Its Geotectonic Significances
-
摘要: 为阐明海南岛西北部早古生代构造演化特征，对海南岛西北部邦溪-晨星地区出露的安山岩展开了详细的岩相学和锆石U-Pb年代学分析.安山岩的主要矿物组成为斜长石、角闪石、黑云母和玻璃质.LA-ICP-MS锆石U-Pb定年结果表明，两个代表性的安山岩样品给出了452±8 Ma和453±8 Ma的形成年龄，暗示海南岛西北部存在早古生代火山作用.这些安山岩的形成时代与冈瓦纳大陆北缘各微陆块记录的早古生代岩浆活动信息相似，在时空上与金沙江-点苍山-哀牢山构造带和印支地块分布的早古生代岩浆岩具有耦合性.综合研究认为，点苍山-哀牢山、Truong Son、Tam Ky-Phuoc Son、Kontum和海南岛等地区可能发育原特提斯洋的支洋盆.Abstract: In order to decipher the Early Paleozoic tectonic evolution of the northwestern Hainan Island, detailed petrography and zircon U-Pb geochronological analyses of andesites in the Bangxi-Chenxing area were carried out in this study. The andesites are mainly composed of plagioclase, hornblende, biotite and glasses. LA-ICP-MS zircon U-Pb dating results show that two representative andesite samples yield ages of 452±8 Ma and 453±8 Ma, indicating that there is andesitic magmatism in the Bangxi-Chenxing area during the Early Paleozoic. The formation age of the andesites is similar to the time of Early Paleozoic magmatism recorded in the micro-continents along the northern Gondwana. They also show a good coupling with the Early Paleozoic igneous rocks in the Jinshajiang-Diancangshan-Ailaoshan tectonic belt and in the Indochina block. Integrated with regional data, the Diancangshan-Ailaoshan, Truong Son, Tam Ky-Phuoc Son, Kontum and Hainan Island were likely to be branch of Proto-Tethys Oceans during the Early Paleozoic.
