@article{10272/10189, year = {1998}, url = {http://hdl.handle.net/10272/10189}, abstract = {A magnetostratigraphic investigation on a Middle-Late Triassic section outcropping at Cuevas de Ayllon (westernmost margin of the Iberian Ranges, Spain) has been performed. The section mostly consists of a thick sequence of interbedded mudstones and sandstones. The age of the sampled formation has been established as Ladinian-Karnian on the basis of palynological assemblages. 123 samples were subjected to a progressive thermal demagnetization up to 680 °C.A multicomponent magnetization behaviour has been observed. The characteristic component could be isolated from 575-620 °C up to 680 ° C, in 74 samples showed both polarities and allowed to define a consistent magnetic zonation. The data presented will contribute to the construction of a standard polarity scale for the Triassic time span}, publisher = {Sociedad Geológica de España}, title = {Primeros resultados magnetoestratigráficos del Triásico Medio-Superior (Ladiniense-Karniense) en la Cordillera Ibérica occidental (Cuevas de Ayllón)}, title = {First magnetostratigraphic results of the Middle-Late Triassic (Ladinian-Carnian) in the western Iberian Ranges (Cuevas de Ayllón)}, author = {Ruiz, V.
