| 摘 要： | 福建沿海地区晚中生代的花岗岩及火山岩中广泛发育基性、中基性的岩墙群,岩墙群岩性为辉绿岩、角闪辉绿岩和石英闪长岩等,并以角闪辉绿岩为主。采集晋江、同安、湄洲岛等地具有代表性的岩墙样品,选择锆石进行SHRIMPU-Pb定年,测试分析结果表明,它们的同位素年龄都比较接近,都形成于96～87Ma之间,是晚白垩世岩浆活动的产物,它们的形成是中国东南沿海晚中生代活动大陆边缘构造—岩浆活动的最后一幕。 |

| Abstract: | Basic-intermediate dikes are universally found in the Late Mesozoic granite and volcanic rocks of the coastland in Fujian Province.Their lithology is composed of diabase,hornblende diabase and quartz-diorite etc,predominated by diabase.The representative dike samples were collected from Jinjiang,Tong'an and Meizhoudao for SHRIMP U-Pb zircon dating.The zircon SHRIMP U-Pb isotopic analytical results indicate that with comparatively adjacent forming ages,ranging from 96Ma to 87Ma,they should have em-placed app... |
