这篇短文回顾了国际地科联志留纪地层分会最近作出的若干决议,推荐的程序和志留系工作者仍面临的一些挑战。 地质科学需要密切的国际合作,也需要有一种严格的、能被正确理解的语言。就这一点而言,没有再比研究地层学感受更强烈了。除有关岩石对时间无休止的哲理讨论外,为试图建立一个全球标准的年代地层学,许多人觉着有一种紧迫感。国际志留-泥盆系界线 This essay looks at a number of recent resolutions, recommended procedures and some of the remaining challenges for Silurian practitioners of the IGLF stratigraphy.
