Then they are able to identify the environmental similarities that established coal-forming swamps in both locations during the Carboniferous Period. Also,A sedimentary structure reflects the depositional environment under which the rock was deposited. Bedding - sediments are arranged into layers defined by bedding planes; usually horizontal, but may also be subhorizontal or curved. Graded bedding - bedding in which the particles are sorted according to density, size, and shape. Normal grading ...The depositional environments interpretations of investigated coal seams indicate that the coals were deposited within a telmatic, limnic, limno-telmatic and open march zone. Generally, a combination of results from inorganic geochemistry and organic petrology is required for precise and all-inclusive determination of coal depositional ...
Aug 1, 2021 · 1. Introduction. During the last three decades, particularly after the discovery of coal-bearing sequences with source rock potential in the North Sea basin, several studies focused on the gas and oil generation potential of humic coals (Hunt, 1991; Fowler et al., 1991; Petersen, 2002, Petersen, 2006; Petersen and Hertle, 2018; Petersen et al., 2013; Sykes, 2004; Wilkins and George, 2002). In the marine environment, Demaison and Moore (1980) recognized a series of depositional settings where source rock might be deposited linked to organic matter preservation. Those ideas were further refined by Demaison et al. (1983) into two basic depositional settings: the ventilated open ocean on the shelf and slope; and silled ……
