A paleosol interpretation for profiles exhibiting subaerial exposure “crusts” from the Mississippian of the Appalachian Basin

Sedimentological, geochemical and paleontological insights applied to continental omission surfaces: A new approach for reconstructing an eocene foreland basin in NW Argentina

“…Moreover, ferruginous concretions (concentric internal laminations) also occur ( Fig. 4F) indicating seasonal growth (Ettensohn et al, 1988).…”

Mineralogy, chemistry, and petrography of soils, surface crusts, and soil stones, San Salvador and Eleuthera, Bahamas

“…Paleoenvironmental interpretations, such as paleoclimate, of paleosols in Paleozoic carbonates are common (Goldhammer and Elmore, 1984;Prather, 1985;Ettensohn et al, 1988;Wright, 1988;Goebel et al, 1989). The objective of this chapter is to describe modern Bahamian soils, pedogenically altered limestones, and the present-day conditions of soil formation, so they can be used as modern analogues to ancient paleosols and aid in their stratigraphic and paleoenvironmental interpretations.…”

Palaeoenvironmental significance of palustrine carbonates and calcretes in the geological record

“…The maturity of the palaeosols may give an idea of the type and range of the sedimentary dis continuity. Etthenson et al (1988) described mature and thick caliche profi les on disconformities related to times of important tectonic activity or regional regres sions, and less mature profi les related to local regres sions, in the Mississippian of the Appalachian. In the southern Madrid Basin, a thick laminar calcrete pro fI le represents the boundary between the Pliocene and the Quaternary (Sanz, 1996).…”
