沉积岩沉积环境研究是地貭发展史的调查基础;在许多情况下,已应用于煤田地质和石油地貭,以及应用于研究矿物或元素组合的富集分布方面,一方面它适用于海相盆地,另一方面也适用于大陆风化壳和陆相堆积的区域。研究这些问题取决于地貭历史时期中海洋分布范围及其海浸和海退过程的了解。 Sedimentary sedimentary environment research is the basis for the investigation of the development history of Castanopsis ortus. In many cases, it has been applied to coalfield geology and petroleum geography, as well as to study the enrichment and distribution of minerals or elemental assemblages. On the one hand, it is suitable for marine basins, On the other hand also applies to the continental weathering crust and continental accumulation area. Studying these issues depends on the understanding of the extent of the oceans and seas and the process of sea-going and retreat in the historical period.
