随着同位素年代方法的完善,对星体地质发展初期的特征掌握的越来越详细而又具体。证明在35—30亿年前,地球表面的温度有150—200℃,有火山熔岩流出现,在它上边又出现了一层酸性的薄层。可靠材料说明在38亿年前就有海盆地存在。在海盆地中沉积了成分近似于现代的砂岩、石灰岩、硅质岩等糟石。在西恪陵兰、东西伯利亚,南非和其它一些地区发现了这些岩石。这些沉积岩的发现,证明所提出的关于在地史早期(前寒武纪时),风化作用和沉积作用(即岩石的破坏及破坏的产物的堆
With the improvement of isotopic dating methods, more and more detailed and concrete descriptions of the features of the early stages of astral geological development have been obtained. Prove that between 35 and 300 billion years ago, the surface of the earth had a temperature of 150-200 ° C and a volcanic lava flow appeared. A thin layer of acid appeared on top of it. Reliable material shows that the basin existed 3.8 billion years ago. In the basin sedimentary composition similar to the modern sandstone, limestone, silicalite and other bad stone. These rocks were found in West Greenland, Eastern Siberia, South Africa and elsewhere. The discovery of these sedimentary rocks proved that the proposed study on the effects of weathering and sedimentation (that is, the product of the destruction and destruction of rocks) in the early history of Prehistoric (Precambrian)
