瑞典 奥陶统 地层学综合研究
2017/8/30
近些年来，奥陶纪碳同位素地层学研究获得重要进展，已经识别出7次显著的碳同位素漂移事件，即为MDICE、GICE、HICE、Kope, Fairview、Waynesville和Whitewater等。其中，在中奥陶世达瑞威尔期，碳同位素值经历一次显著漂移事件，即达瑞威尔中期碳同位素漂移事件（MDICE）。与此同时，海洋生态系统历经一次重要的变革，记录了奥陶纪生物大辐射的第二次峰值。因此，对中奥陶统...

月球内部据断“水分含量惊人”
美国 月球 水
2017/7/27
曾被认为干燥的月球，内部可能含有大量的水。这是美国科学家借助卫星数据，分析月球上古代火山沉积物后得出的最新结论。
美国布朗大学研究人员在新一期英国《自然·地球科学》杂志上报告说，月球表面数量众多的火山沉积物里含有“异常高含量的水”。这进一步显示，月幔中可能也“水分含量惊人”。
