Summary
Abstract: Project: LATE CRETACEOUS PALEOGENE > Biogeographic relationships
between northern Antarctic Peninsula and southernmost South America
during the Late Cretaceous-Paleogene. Project No.12 2002 -2004

ENGLISH
The aim of this project is to contribute to the geological and
paleontological knowledge of the Late Cretaceous-Paleogene sedimentary
units of the James Ross (Antarctic Peninsula) and Austral (South
America) basins in order to compare the geological and biological
evolution of these two areas.

Late Cretaceous-Paleogene richly fossiliferous sedimentary rocks are
presently exposed at both sides of the Drake Passage in the James Ross
Basin (Antarctica) and Austral or Magallanes Basin (South
America). The physical link between Antarctic Peninsula and Patagonia,
at least from Cretaceous to Eocene times, has been fully proved and
therefore these basins must have been adjacent one to the
other. Therefore the comparative study of these basins is very
important to understand not only the geological evolution of the area
but also the composition and evolution of the fauna and flora of these
southern high latitude areas. This knowledge will also help to
understand the origin and evolution of modern fauna and flora in
southern continents.

In the James Ross Archipelago (James Ross Basin) superb exposures of
fossiliferous marine sedimentary rocks record the events from
Coniacian up to Eocene times in the northern Antarctic
Peninsula. Glacimarine and volcanic deposits represent Neogene glacial
and volcanics events. At the same time, in southernmost South America,
an important time-equivalent sedimentary sequence accumulated in the
Austral Basin and crops out in southern Santa Cruz and Tierra del
Fuego provinces.

Relaciones Biogeograficas entre el extremo norte de la Peninsula
Antartica y el extremo austral sudamericano durante el Cretacico
Superior-Paleogeno

La union fisica entre la Peninsula Antartica y Patagonia desde al
menos el Cretacico hasta el Eoceno ha quedado plenamente probada y
ahora se especula sobre los acontecimientos que llevaron a su
separacion y condujeron a las placas a su distribucion actual
(Cunningham et al., 1995). Por lo tanto, mientras que en el extremo
norte de la Peninsula Antartica (Cuenca James Ross) se depositaban las
unidades actualmente aflorantes en la islas Marambio, en el NW de la
isla James Ross y Vega, (vease una sintesis en Elliot, 1988 en
Feldmann y Woodburne, 1988), en el extremo sur de Sudamerica tenian
lugar eventos geologicos que han quedado registrados, junto con sus
fosiles, en las sedimentitas del Cretacico Superior-Paleogeno de la
Cuenca Austral (Biddle et al., 1986; Macellari et al., 1989). Es por
ello que el estudio de estas ultimas y su comparacion con Antartida es
de gran importancia para conocer no solo la evolucion geologica de
toda esta vasta region, sino tambien la composicion y evolucion de la
fauna y flora de esos mares y tierras australes y comprender su rol en
el desarrollo de las faunas y floras modernas de todo el Hemisferio
Sur.

En las islas Marambio, Vega y James Ross, rocas sedimentarias
mayormente de origen marino, muy fosiliferas, registran los
acontecimientos ocurridos en el norte de la Peninsula Antartica
durante el lapso Coniaciano-Eoceno (Cuenca James Ross). Depositos
glacimarinos y vulcanitas neogenas representan los eventos magmaticos
y glacigenicos mis recientes (Rinaldi et al., 1978; Feldmann y
Woodburne, 1988; Marenssi et al., 1998a). En el extremo austral
sudamericano una extensa secuencia sedimentaria representa el relleno
de la Cuenca Austral. Rocas equivalentes en edad a las aflorantes en
la isla Marambio, Vega y noroeste de la isla James Ross (y aun mas
antiguas), se hallan en las provincias de Santa Cruz y Tierra del
Fuego (Macellari et al., 1989; Malumian y Carames, 1997; Olivero y
Malumian, 1999, entre otros).

En consecuencia, este proyecto pretende acrecentar el conocimiento de
la estratigrafia, sedimentologia y paleontologia de las diferentes
unidades del Cretacico Superior-Paleogeno de la Cuenca James Ross
(Antartica) y su comparacion con aquellas coetaneas de la Cuenca
Austral (Patagonia). Especificamente, se pretende cristalizar las
investigaciones que el grupo ha venido realizando en los ultimos anos,
produciendo un mapa geologico de la isla Marambio de resolucion acorde
con la base topografica disponible (1:10000 equidistancia 5 m).
