国际地质对比计划第160号专题“先寒武的外成作用”,已于1979年全面执行。它的内容是研究先寒武岩石的沉积学和火山学以及这些岩石在成岩作用过程中所发生的变化。研究结果表明,我们已面临一项大的突破,这项突破有可能从根本上影响先寒武地质学的某些概念。 在火山-沉积地体和成岩作用研究中所取得的进展,大都是由于应用了均变作用-反应模型(Uniformitarin Process-response models)而取得的。虽然我们可以观察到古老岩石的结构和构造,但我们不能
The International Geological Correction Project Special Topic No. 160 “Outreach Effect of Precambrian” was fully implemented in 1979. Its content is to study the sedimentology and volcanology of pre-Cambrian rocks and the changes that these rocks took during their diagenesis. The results of the study show that we have faced a major breakthrough that is likely to fundamentally affect some of the concepts of Precambrian geology. Much of the progress made in volcanic-sedimentary and diagenetic studies is due to the use of Uniformitarin Process-response models. Although we can observe the structure and structure of ancient rocks, we can not
