大陆溢流玄武岩,即CFB,是与大陆裂谷伴生的具有重要地质意义的一类玄武岩,是目前学界研究的核心问题之一。对于大陆溢流玄武岩的成因,地球化学特征等内容更有可能是推动地质学发展的核心问题。介绍大陆溢流玄武岩产出的地质背景,地球化学特征以及地质意义。认为多数大陆溢流玄武岩省是以相对演化的拉斑玄武质喷发为主,部分的酸性喷发物主要是地壳混染的结果。
The continental overflow basalt, or CFB, is a type of basalt with important geological significance associated with the continental rift. It is one of the core issues in current academic research. The origin, geochemical characteristics and so on of the overflow basalts in China are more likely to be the core issue in promoting the development of geology. Geological background, geochemical characteristics and geologic significance of continental overflow basalts production are introduced. It is believed that most continental overrun basalts provinces are dominated by relatively developed tholeigenic basaltic eruptions, and some acidic eruptive matters are mainly the result of crustal contamination.
