Epizoan-sponge Interactions in the Early Ordovician of the Argentine Precordillera

PALAIOS, 2000
Abstract Evidence for biotic interaction is not obtainable easily in the fossil record. Epizoans cemented to the skeletons of host organisms provide an opportunity to study possible host–epizoan interactions and the ecological structure of hard substratum communities.

Ordovician accretion of the Argentine Precordillera terrane to Gondwana: a review

Journal of South American Earth Sciences, 2003
Abstract The Precordillera terrane of Argentina was rifted as a lithospheric block from the Ouachita embayment of southeastern Laurentia and accreted to western Gondwana. In various interpretations, the time of rifting of the Precordillera terrane from Laurentia ranges from Early Cambrian to Late Ordovician, and the time of accretion to Gondwana ...

Polyphase structural evolution of the southwestern Argentine Precordillera

Journal of South American Earth Sciences, 1995
Abstract The western and southwestern parts of the Argentine Precordillera display complex geometries which are not consistent with those of a typical high-level fold-and-thrust belt. They are the result of a polyphase structural evolution which spans the Early Paleozoic to Late Tertiary period.

Cambrian phosphatic brachiopods from the Precordillera of western Argentina

GFF, 1999
Abstract The first Cambrian phosphatic brachiopods (Subphylum Linguliformea, Class Lingulata) are described from the San Juan Precor-dillera of western Argentina, including Neotreta tumida Sobolev, Quadrisonia minor Rowell & Henderson, Prototreta cf. mimica Bell, Curticia sp., Opisthotreta sp.

The structural evolution of the northern San Juan Precordillera, Argentina: A review

Journal of South American Earth Sciences
AbstractThis study is based on the construction of six structural cross-sections integrating recent outcrop mapping and newly acquired reflection seismic data from the Jáchal Valley, together with reprocessed legacy seismic lines, data from deep exploratory boreholes, and crustal seismicity beneath the Bermejo Valley.

Argentina Devonian (Western Precordillera)

2016
En la Precordillera Occidental, en Argentina, el límite Devónico/Carbonífero se caracteriza por una discordancia angular, donde los depósitos del Devónico Inferior a Superior (Emsiano tardío-Frasniano temprano) de la Formación Chigua están plegados debajo de los estratos homoclinales del Mississippiano (Tournaisiano tardío-Viseano temprano) de la ...
