PRELIMINARY GENERAL PROGRAM
1st day: Metamorphic basement of Sierra de Maz (Mesoproterozoic Protoliths and superposed metamorphic events).
2nd day: Mesoproterozoic anorthosites of Maz and Neoproterozoic sienitic-carbonatitic alcaline magmatism.
3rd day: Río Bonete cross section, Transcurrent zone and supposed emplacement of the Precordillera terrane. Late Ordovician cover of pillow-lavas (Famatinian ophiolites). Famatinian magamtic arc in the upper plate (Sierra de Famatina).
4th day: Guandacol region. Early Paleozoic Laurentian carbonate platform and development of the tectonic wedge and ocloyic syn-orogenic sedimentation in the peripheric foreland of the Precordillera terrane.
5th day: Transect of Laguna Brava showing Gondwanan (mainly Carboniferous-Permian) cover, series of Mesozoic rifts and development of the Andean syn-orogenic wedge with excellent exposures of the Paleogene and Neogene cycles. Observations of the basement of the Cordillera Frontal (Chilenia?) and Permo-Triassic intrusives of the Choiyoi magmatic province.
No technical difficulties.
Possibility of visiting the Cuesta de Miranda transect and the Ischigualasto bolsón in the way La Rioja-villa Unión- La Rioja
Field trip will be with intensive activities all days. Every day must go in and out of the visiting zone. All nights and diners at Villa Unión.

Pre-Registration – Deadline May 20th 2010
POST CONGRESS MAIN FIELD-TRIP
24 to 26 November 2010
Three-day trip departing and returning to Mar del Plata
Cost : 350 US$
Your registration includes:
- transport by bus or minibus or 4WD from Mar del Plata and return.
- accommodation in the hotel (***) in double rooms
- all breakfast, lunches, dinners;
- field trip guide.
PRELIMINARY GENERAL PROGRAM
During the field trip we´ll visit the southern exposures of the Rio de la Plata craton, to the north of its boundary with Patagonia. The first day will be devoted to visit several important sites along the Tandili system where a Paleoproterozoic basement is covered by a complex succession of clastic and carbonatic units of Ediacaran to Early Paleozoic age. Visits would include type sections at Olavarria, Barker and other localities and will encompass different platform deposits and glacial(?) diamictite.
In Sierra de la Ventana the field trip will comprise a two day transect through the Permian (Gondwanide) Sierra de la Ventana Fold Belt and the Sauce Grande Basin, the South American counterpart of the Cape Fold Belt and the Karoo Foreland Basin from South Africa. Selected stops will show the lithology and structure of the Precambrian-Cambrian basement and the Palaeozoic to Triassic sedimentary cover. Stops will include exposures of the basement-cover contact, the Cambrian to Devonian platform quartzites (Curamalal and Ventana Groups) with their spectacular similar type folds, the Gondwanan glaciation (Sauce Grande Fm diamictites) and related postglaciation sequences (Piedra Azul and Bonete Fms) as well as the fill of the foreland basin stage (Tunas Fm).
