Shale formation environment
In this chapter, we focus on As within a select group of hydrocarbons and source rocks, including crude oil, natural gas, oil shale, gas shale, and oil sands. We provide short descriptions of these sources in Table 1 , but for a more in-depth discussion of hydrocarbon formation, we refer the reader to textbooks (e.g., Tissot and Welte, 1984 , …The development and accumulation of oil shale are also affected by tectonics. In a fault basin, the synsedimentary faults influence the formation and accumulation of oil shale by controlling the sedimentary environment. The oil shale tends to be mainly distributed on the thrown side of the basin-controlling fault with the greater thickness.The Barnett Shale is a set of black carboniferous shales developed in the Fort Worth Basin of Texas in the USA, with an area of distribution of approximately 1.3 × 104 km 2. It is the most important hydrocarbon source rock formation in the Fort Worth Basin.

The Bowland Shale is a Carboniferous formation located in the north of England, which sits on top of the Worston Shale Group, and below the Millstone Grit Group [].This formation is subdivided into the Upper and Lower Bowland Shale, the former is a siliciclastic system while the latter is carbonate-dominated [].The gas in the Marcellus Shale is a result of its contained organic content. Logic therefore suggests that rocks that contain higher amounts of organic material have a greater ability to generate natural gas. A map showing the net feet of organic-rich shale in the Marcellus Formation can be viewed on this page.
Dec 1, 2018 · Formation of organic-rich shale depends on living environment of hydrocarbon-generating parent organisms, and is also affected by preservation condition of organic matter (Zhao et al., 2016). Therefore, the reconstruction of paleo-ocean sedimentary environment is of great theoretical significance to reveal development and evolution ... The Morrison Formation, which was named by G. H. Eldridge in 1896 (in Emmons, Cross, and Eldridge, 1896), consists of shale, sandstone, and limestone, and small amounts of chert and anhydrite. Shale is the predominate lithologic type (Merriam, 1955a). Two distinct lithologic units of the Morrison Formation are recognizable in Kansas. ….
