“…and Appel (1990) reported extensive outcrops of WPB (which commonly display high contents of vesicles) and IAT (with almost no vesicles). According to Azema et al (1979a) and Baumgartner et al (1984). interpillow sediments assign these basalts an early Paleocene age.…”

“…This model implies that (I) the entire Nicoya Complex, including radiolarites and WPB, has a Pacific origin, but now lies upon Caribbean crustthis would account for the anomalously thick crust underneath Costa Rica (40km; Matumoto et al, 1977); (2) the Caribbean sill event would not have had any direct effects upon the arc; (3) fAT volcanism would have stopped from the Santonian onward. Baumgartner et al (1984) and Astorga (1988), however, report some minor volcanic activity from the early Campanian. The strong point of this model is that it explains satisfactorily the drastic spatial, temporal, and genetic separation between the Nicoya Complex and the calc-alkaline arc.…”

“…En 1984 con la publicación del primer núme-ro de la RGAC, Baumgartner et al (1984) realizan un artículo muy detallado sobre "Sedimentología y Paleogeografía del Cretácico y Cenozoico del litoral Pacífico de Costa Rica", que presenta con una visión diferente, la estratigrafía de la región que había sido propuesta originalmente por Dengo (1962) y no había sido revisada con profundidad desde esa fecha. El trabajo es una contribución importante porque incluye elementos en ese momento "novedosos" en la geología de Costa Rica, como son los aspectos sedimentoló-gicos y el levantamiento de columnas estratigráfi-cas muy detalladas.…”
