Relationship of Clay Minerals to Depositional Environment in the Non-Marine Eocene Pontils Group, Se Ebro Basin (Spain)

Fluvial and Marine Depositional Environments Determined From Groundwater Chemistry and Calculated Clay‐Cation Compositions

“…Traditional differentiation of fluvial and marine environments requires acquisition, interpretation, and integration of extensive amounts of outcrop data, tens to hundreds of well core and logs, seismic and paleontologic data (e.g., Brekke & Roenitz, 2021; Casson et al., 2021; Greb et al., 2021; Kjaerefjod et al., 2022; Knox et al., 2006; Zhang et al., 2020). Often there is inadequate availability or access to these data, in which case much of the evaluation is based on outcrop or examination of well cuttings or core for clay mineral percent assemblages, distribution, and depositional patterns to give information on the environment of deposition of the sediments (e.g., Al‐Mojel et al., 2020; Chamley, 2001; Freed, 1980; Ingles & Anadon, 1991; Ingles & Ramos‐Guerrero, 1995; Waters et al., 2020; Xu et al., 2017). Few studies, however, have been done to characterize the clay distribution along the fluvial to marine transition zone in a coastal environment (e.g., Gugliotta et al., 2020).…”

Distinguishing Similar Volcanic Source Areas From An Integrated Provenance Analysis: Implications for Foreland Andean Basins

“…Clay-mineral assemblages that were affected only by eodiagenetic processes thereby become significant in unraveling the depositional history of fine-grained sedimentary rocks in ancient sequences. Consequently, the clay-mineral assemblages have been a useful tool to the study of a variety of sedimentary basins around the world (Chamley 1989;Ingle `s and Anado ´n 1991;Ingle `s and Ramos-Guerrero 1995;Adatte et al 2002;Net 2002;Do Campo et al 2010). Clay minerals are the common products of weathering and authigenesis, while clay assemblages are the result of the complex interaction of several variables affecting continental sediments (Do Campo et al 2010), including source-area lithology, continental basin morphology, depositional environments, and paleoclimate (Chamley 1989).…”
