Item Presencia y caracterización del "Alcudiense superior" (Vendiense) en el entronque de La Serena y El Valle de Alcudia (Este de la Provincia de Badajoz)(II Congreso Geológico de España, Granada 1988., 1988) Pieren Pidal, Agustín Pedro; Herranz Araújo, PedroUpper Alcudian series are studied in a new location in westernmost Alcudia Valley (Badajoz). Basal angular unconformity, inner disconformities, and the presence of dolos tones and ichnofossils suggesting the stratigraphic environment of these facies, are described. The paleogeograhic implications, as well as the magnitude of the intra-alcudian, sardic and taconic phases in this area are discussed. Finally the Upper Alcudian series are compared with known Upper Alcudian of neighbor areas.Item The Lusitanian-Marianic area as a new zone of the Hesperian massif.

(Ciudad Real, Central Spain)(Journal of conference abstracts, 1999) Pieren Pidal, Agustín Pedro; García Hidalgo, J.F.Item Asociaciones palinológicas del tránsito Rhaetiense-Hettangiense en Asturias (España)(Geotemas, 2005) Barrón López, Eduardo; Gómez Fernández, Juan José; Goy Goy, Antonio; Pieren Pidal, Agustín PedroThe palynological study of 49 successive samples collected from the Vilorteo and Cantavieyo Diamond Drill Holes, drilled in the La Camocha Mine area, near Gijón (Asturias), allowed the characterization of three palynological assemblages. The oldest assemblage (PA 1) is characteristic of the Rhaetian. A precise age for the middle assemblage (PA2) cannot be assigned, due to the scarce productivity of the samples. The youngest assemblage (PA3) is characteristic of the Hettangian. Consequently the Triassic-Jurassic boundary (TJB) is located within the upper part of the carbonate succession of the Solís Mb. Two pa/ynozones, Rhaetipollis germanicus one and Krausselisporites reissingeri Zone, have been established. Their boundary nearly coincides with the TJB. A quantitative analysis reveals an increase in the proportion of hygrophilous and warmer taxa near the TJB, compatible with a global climatic change probably related with the end-Triassic mass extinction.
