Evidence for middle Cretaceous accretion at Santa Elena Peninsula (Santa Rosa Accretionary Complex), Costa Rica (2006)

P. O. Baumgartner, P. Denyer

An oceanic assemblage of alkaline basalts, radiolarites and polymictic breccias forms the tectonic substratum of the Santa Elena Nappe, which is constituted by extensive outcrops of ultramafic and...

Magmatic and geotectonic significance of Santa Elena Peninsula, Costa Rica (2006)

E. Gazel, P. Denyer, P. O. Baumgartner

We present a new integrated interpretation of the geochemistry and geotectonic significance of the Santa Elena Peninsula, which is divided in three units: 1) an overthrust allocthonous unit of...

Emplacement of Jurassic-Lower Cretaceous radiolarites of the Nicoya Complex (Costa Rica) (2006)

P. Denyer, P. O. Baumgartner

We present a new model to explain the origin, emplacement and stratigraphy of the Nicoya Complex in the NW part of the Nicoya Peninsula (Costa Rica) based on twenty-five years of field work,...

Characterization and tectonic implications of Mesozoic-Cenozoic oceanic assemblages of Costa Rica and Western Panama (2006)

Characterization and tectonic implications of Mesozoic-Cenozoic oceanic assemblages of Costa Rica and Western Panama (2006)

Denyer, P., Baumgartner, P.O., Gazel, E.

The Pacific face of Costa Rica and western Panama has been extensively studied because of the wide occurrence of oceanic assemblages. In Northern Costa Rica, the Santa Elena Nappe made by ultramafic...

Magnetobiostratigraphic synthesis of Leg 123: sites 765 and 766 (Argo Abyssal Plain and Lower Exmouth Plateau) (1992)

Kaminski, M.A., Baumgartner, P.O., Bown, P.R., Haig, D.W., McMinn, A., Moran, M.J., ...

During ODP Leg 123, Sites 765 and 766 were drilled to examine the tectonic evolution, sedimentary history, and paleoceanography of the Argo Abyssal Plain and lower Exmouth Plateau. At each site, the...
