The sediment preservation potential is very high in these environments because deposition often occurs on the continental shelf and underwater. Shoreline environments are an important source of hydrocarbon deposits (petroleum, natural gas). The study of shoreline depositional environments is called sequence stratigraphy. Sequence stratigraphy ... The paleo-sedimentary environment can be restored qualitatively or semiqualitatively using elements or combinations of elements that are sensitive to the depositional environment. Through the analysis and testing of the main elements, trace elements and rare earth elements of twenty-one Lower—Middle Permian coal-bearing …Deposition occurs when the sea loses energy and drops any matter that it may be carrying. Deposition is a coastal process. In geography, deposition refers to the way that constructive waves are developed.During carbonaceous-mudstone deposition, many higher-plants were lived nearby and well preserved, but when the site was transitory flooded by river, debris and exogenous organic matter became the main sediments. At the time of mudstone deposition, the depositional environment changed to a freshwater condition with periodical influence of flood.

Although difficult, recognition of microbial laminae is possible, and can lead to substantially different interpretations of mudstone environments (Schieber, 1999a). Silty mudstone clasts within the limestone beds, and prominent localized silty mudstone horizons, indicate fluctuations in depositional energy. In part, these may have resulted from minor topographical variations in the sea floor, with fine-grained sediment winnowed from topographic highs being preserved in low-lying areas.
