作为地质年代测定的基础是史泰侬 (Stenon)于 17世纪提出的三原则 ,即 :叠加、连续性和原始水平性。这些原则又源于一项沉积学假设 :土壤下的各层都是古老连续沉积的地层。因而地层学是以沉积学资料为基础的。现根据连续观察和实验室的实验结果认为 :史泰侬的地层学模型与实验数据不符 ,因为他忽略了沉积学中的主要因素 :流动及其时序效应。沉积过程可以分为 3个阶段 :冲刷、搬运和沉积物的积淀 ,而非静态的液流正是搬运的因素。史氏仅考虑到第 3阶段———沉积 ,且假设液流的速度为零。模拟了由不同颗粒度和具有不同速度生成的诸多沉积层的构造 ,将液流的时序重新组合到作者的科学见解的范围内 ,而这对于在沉积学 ,地层学和地质年代测定的相互链接的顺序中是必不可少的。作者引入古水力学作为地质年代确定的新方法 ,从而把这个链条的两端连接起来 ,而把对喷发岩的放射年代测定法视作非常规的方法。总之 ,古水力学这一新方法导致了实验沉积学的建立 ,而且此前的静态的地层学和地质年代学的假设和原理都应重新接受从现场观察和实验室实验得出的数据资料的检验
The basis for dating the geology is the three principles proposed by Stenon in the 17th century: overlay, continuity and primitiveness. These principles, in turn, originate from a sedimentary hypothesis that all layers under the soil are ancient and continuously deposited strata. Stratigraphy is based on sedimentology data. Based on the continuous observations and experimental results of the laboratory, it is concluded that the Strathern strata model does not match the experimental data because he neglected the major factors in sedimentology: flow and its timing effects. The deposition process can be divided into three stages: erosion, handling and sediment deposition, rather than static flow is the handling factor. Smith only considered Stage 3 - sedimentation, and assumed that the velocity of the flow was zero. Modeling the construction of many sedimentary layers formed at different particle sizes and at different velocities regrourizes the timing of the fluid flow to the extent of the authors’ scientific insights that are important for the interlinkage between sedimentology, stratigraphy, and geochronology The order is essential. The authors introduced paleo-hydraulics as a new method for determining the geologic age, thereby linking the two ends of the chain and treating radiometric dating of eruption rocks as an unconventional method. In summary, the new approach to paleo-hydraulics led to the establishment of experimental sedimentology, and the previous assumptions and principles of stratum and geochronology should be re-examined by data from field observations and laboratory experiments
