[Renata Nela Tomezzoli]

Estimados colegas: aprovecho el mail anterior enviado por el Dr
Martino para invitarlos a participar en el "Gondwana 14 meeting", en
la sesión Gondwanides:


Gondwana 14 meeting which will be held September 25th-30th, 2011, in the
coastal city of Armação de Búzios in Brazil.

We invite you to the SESSION 2 – GONDWANIDES

Conveners: I. Dalziel (USA), Renata Nela Tomezzoli (Argentina) and
Maarten de Wit (South Africa);  ian en utig.ig.utexas.edu,

The Gondwanide Orogeny: In his classic 1937 book "Our Wandering Continents",
the South African geologist Alex Du Toit mapped his "Samfrau Geosyncline" from
the Sierra de La Ventana of Argentina into the Cape Mountains of South Africa
and through a then unknown part of Antarctica to eastern Australia. He thereby
used widely separated parts of what we now call the Gondwanide orogen as
piercing points in reconstructing Gondwanaland and arguing for the hypothesis of
continental drift. With the aid of marine and satellite geophysics, detailed
geologic studies and paleomagnetism, we can now accurately trace the
Gondwanides from South America and Africa through the restored Lafonian and
Ellsworth-Whitmore microplates to the Pensacola Mountains along the
Transantarctic Mountains front. There are, however, several outstanding
questions concerning the orogen, the nature and the cause of the Gondwanide
orogeny. Does the orogen really extend to eastern Australia? Did all the
deformation of the Cambrian to Permian succession occur after the deposition of
Glossopteris-bearing Permian strata, or was there an earlier phase? What was
the cause of the deformation in an orogen far inboard of the Pacific margin of
Gondwanaland, at least in South American, Africa and Antarctica?
The session is planned to bring together workers in every sector of
this important
and enigmatic, and now far flung orogen. A Gondwana meeting on the Atlantic
coast of South America seems an ideal place to convene such a session.

> The deadline for abstract submissions is 30th of April 2011.  Registration

> According to the website Búzios is: “a cozy and charming resort in the
> eastern coastal region of Rio de Janeiro State Brazil. Sixteen beautiful
> beaches compose the sightseeing with amazing outcrops of Cambrian gneisses
> that register the latest orogeny related to Gondwana amalgamation. In
> addition, tholeiitic diabase dykes associated with Mesozoic-Cenozoic faults
> complete the history of Gondwana break up and development of the South
> Atlantic margins. Mild temperatures and dry weather in the end of September
> configure the beginning of spring, with flowers and fruits all over”.
