美国科学家最近提出,两亿年前地球上曾发生了一次迄今为止最为强烈的火山爆发,使古大陆分裂,从而形成了今天的大西洋。 据美国《科学》杂志报道,这一假设是加利福尼亚大学伯克利分校的研究人员保罗·伦尼及其同事提出的。他们对从美国新泽西州到西非的环大西洋的火山岩进行研究后认为,这些火山岩可能是由同一次火山爆发形成的。 U.S. scientists recently proposed that two hundred million years ago Earth Earth had witnessed one of the most intense volcanic eruptions to date, splitting the ancient continent and forming today’s Atlantic Ocean. According to the U.S. Science, this hypothesis was made by Paul Lenny of the University of California, Berkeley, and colleagues. After studying the ring-shaped Atlantic volcanic rocks from New Jersey to West Africa in the United States, they believed that these volcanic rocks may have been formed by the same volcanic eruption.
