哥伦比亚超大陆(Nuna-Colmbia,17~13亿年)和罗的尼亚超大陆(Rodinia,11~7亿年)的重建一直是地球科学家极感兴趣,也是多年来存在很多争论的科学问题。大火成岩省的分布和特征是古大陆重建的有效途径之一。加拿大卡尔顿大学的Ernst博士等人通过新的U-Pb和Ar-Ar年龄数据
The reconstruction of the Nuna-Colmbia (1.7-1.3 billion years) and Rodinia (1.1-700 million years) of the Columbia continent has been of great interest to geoscientists and has been a scientific issue that has been debated for many years. The distribution and characteristics of large igneous provinces is one of the effective ways to rebuild the ancient continent. Ernst, PhD, of Carleton University in Canada passed the new U-Pb and Ar-Ar age data
