[Geoinfo] evolución geológica de los Andes en GSA Connects 2025

[Juan OTAMENDI]

Estimadas y estimados colegas de la comunidad geológica:



Me complace compartir con ustedes una invitación para la próxima edición de
GSA Connects 2025. En esta ocasión, tendremos una sesión dedicada a
discutir los avances del conocimiento en la evolución geológica de la
Cordillera de los Andes desde el Paleozoico hasta la actualidad.



Incluyendo charlas invitadas de:

María Pía Rodríguez (University of Andres Bello, Santiago, Chile)

Veleda Muller (University of Arizona, USA)


Para aquellas y aquellos que tengan en su agenda participar del GSA, éste
será un ambiente científico de interés para la comunidad sudamericana.


Abajo pueden encontrar los detalles preliminares sobre la sesión.



Saludos cordiales



Juan Otamendi

*T36. Building the South American Cordillera, Paleozoic to Recent: Insights
from Geo-Thermochronology*



*Session Type:* Topical Sessions

*Description:*

An overview of the lithospheric development of the South American
Cordillera since the Paleozoic.

We invite submissions that utilize geochronology and thermochronology data
for basement evolution, structural geology, basin analysis, and landscape
evolution.



*New! Early Abstract Submission Deadline*

Planning to present in San Antonio? Submit your abstract early to receive
decisions sooner and ease travel planning. Especially helpful for
international presenters needing time for visas, travel, and logistics.



Abstracts Submissions Open: *1 May*

Early Submission Deadline: *15 May*

Final Deadline: *5 August*



*Session Description *

This session explores the lithospheric evolution of western South America
from Paleozoic to present time, highlighting studies of basement tectonics,
basin analysis, and landscape development that incorporate age data.
Western South America has been dynamically active since the late
Precambrian, preserving records of multiple episodes of terrane accretion,
orogenesis, and continental growth culminating in today’s modern Andean
setting. The margin also hosts stratigraphic sequences deposited during
significant intraplate and arc-related basin episodes, influenced by
various greenhouse and icehouse climate cycles. Understanding the timing of
these tectonic and climatic events, alongside sedimentary routing
processes, is crucial for reconstructing the paleogeographic and geological
history of this vast landmass throughout the Phanerozoic. Such research
benefits from the application of a diverse array of geochronology and
thermochronology methods capable of examining a wide range of lithologies
across varying temperature regimes.


The study of the western Southern American margin through time aligns with
the meeting theme of Geology Without Borders. Research on the development
of the North American Cordillera is often well-represented at GSA meetings,
and this session aims to feature high-quality research on its southern
counterpart and contribute to a comprehensive understanding of the entire
American Cordillera. We particularly encourage contributions from South
American geologists to foster stronger ties between research communities in
the Americas.
