Sedimentary depositional environment
In geology,sedimentary depositional environment describes the combination of physical,chemical and biological processes associated with the deposition of a particular type of sediment and,therefore,the rock types that will be formed after lithification,if the sediment is preserved in the rock record.In most cases the environments associated with particular rock types or associations of rock types can be matched to existing analogues.However,the further back in geological time sediments were deposited,the more likely that direct modern analogues are not available
沉积环境
地质学中,沉积环境是有关特殊形态的沉积物的物理、化学及生物化的过程.因此,如果岩石层内含有沉积物,土壤会被石漠化而形成各种各样的岩石.在多数情况下,环境和特殊形态的岩石有关,或岩石的种类能和现存的类似物相联系.然而,沉积物形成的年代越晚,最近代的岩石类似物就越不可能存在.
