A lithofacies terrain model for the Blantyre Region: Implications for the interpretation of palaeosavanna depositional systems and for environmental geology and economic geology in southern Malawi

Age and mineralogy of supergene uranium minerals — Tools to unravel geomorphological and palaeohydrological processes in granitic terrains (Bohemian Massif, SE Germany)

“…10 Ma under the subtropical conditions in the granitic terrain under study. Areas that underwent a polycyclic process of planation and incision, such as central Africa, show a much more reliefed/staircase landscape than central Europe with its geomorphological processes verifiably dating back to the Paleogene or even to the Cretaceous (Dill et al, 2005). A stage which covers planation and exposure, resulting in the formation of domal structures such as inselbergs lasted under the subtropical paleoclimatic conditions during the Neogene for a period of time of as much as 2 Ma.…”

Lithofacies and depositional setting of a highly prospective lacustrine shale oil succession from the Upper Cretaceous Qingshankou Formation in the Gulong sag, northern Songliao Basin, northeast China

“…Organic mudstones are highly heterogeneous and have a complex inorganic mineralogy that varies vertically and laterally at different scales (Macquaker and Adams, 2003). The term "lithofacies," as defined by Eberzin (1940), is the basic unit that constitutes a shale reservoir, reflecting an integration of all the important lithologic features of sedimentary rocks, such as mineral composition, organic matter content, rock texture, sedimentary structure, bedding, color, size distribution, roundness, and sorting (Dill et al, 2005). The global success of shale oil exploration shows that the lithofacies characterization is an effective and significant approach to allow understanding of the accumulation of organic matter, depositional processes, chemical characteristics of the water column, and most importantly, identification of favorable reservoir intervals (Loucks and Ruppel, 2007;Wang and Carr, 2012;Newport et al, 2016;Tang et al, 2016).…”

Lithofacies characteristics and its effect on gas storage of the Silurian Longmaxi marine shale in the southeast Sichuan Basin, China

“…Eberzin (1940) first used the term "lithofacies" in geology to describe the lithological characteristics of sedimentary rock. The lithofacies characteristics could be described by partially qualitative and partially quantitative parameters, including mineral composition, texture, structure, bedding, color, size distribution, roundness and sorting (Dill et al, 2005). Before the successful development of shale gas, studies of lithofacies focused on conventional sandstone and carbonate reservoirs, which reflect their sedimentary setting and process.…”
