| 摘 要： | 粤东地区中生代岩浆活动十分强烈．形成了遍及全区的火山－侵入杂岩。作者根据区域火山－侵入杂岩的地质地球化学的系统研究．结合区域地质、地球物理和西太平洋板块构造格局的研究成果，认为粤东地区中生代岩浆作用的大地构造背景不同于安第斯型活动大陆边缘．具有大陆板内向活动大陆边缘过渡的特征，构造变动和相应的岩浆活动是在中生代全球构造运动背景之下．亚洲大陆板块与南半球洋中脊体系和库拉－太平洋板块三者之间共同作用的结果．

| Abstract: | The Mesozoic granitic volcaoic-intrusive complexes are widely dispersed over the eastern Guangdong area. According to geological and geochemical studies on the complexes, and research results of regional apology and regional geophysics as well as the tectonic framework of western Pacific, it is concluded in this poper that the tectonic background of Mesozoic magmatism is different from active continental margin of Andes type,and has transition characteristics between within-plate of continental plate and active continental margin. The tectonic changes and related magmatic activities are the results that Asian continental plate, E-W trending mid-oceanic ridge system of south hemisphere and Kula-Pacific plate acted each other. |
