What happened to the organic matter from the Upper Cretaceous succession in Guatemala, Central America?
2021, Marine and Petroleum GeologyCitation Excerpt :These members were also studied in details using micropalaeontological methods by Fourcade et al. (1999), providing new data on the stratigraphy of the Cretaceous formations in this area, including the identification of the Angostura Formation (upper Campanian–Maastrichtian) composed of limestone with alveolinids and rudists, defined by Sánchez Montes de Oca in 1979 in Mexico and determining the Actelá Formation near the Cretaceous–Paleogene (K–Pg) transition, composed of limestone breccias. The K–Pg has been further investigated by Stinnesbeck et al. (1997), Fourcade et al. (1998), and Keller and Stinnesbeck (2000). According to Fourcade et al. (1999), the Maastrichtian in the South Petén basin, northern Guatemala, is represented by the two formations, depending on the locality: (1) Sepur, represented by deep-water deposits and (2) Angostura, typically containing rudists and large benthic foraminifera.
