Informe final: Tertiary Successions in Chile - Fondecyt 1130006 (J.P. Le Roux) El Proyecto Fondecyt 1130006 comenzó en marzo del 2013 y generó 3 artículos en revistas ISI durante los primeros 3 años, además de 7 ponencias a congresos internacionales. En septiembre del 2015 se organizó un simposio científico de 2 días en Lonquimay, que tuvo por finalidad presentar los diversos estudios realizados a las comunidades Mapuches y el público en general. Un memorista (Hermán Rivas) se tituló como geólogo al fines del 2015. Durante el 2016 las investigaciones continuaron en las áreas de Magallanes, Lonquimay y Antofagasta, en las que participaron Jacobus Le Roux, Nestor Gutíérrez, Huber Rivera, Viviana Pedroza, y Benjamin Bahamondes. El trabajo del último fue bajo la tutela de Jacobus Le Roux, pero ha sido parcialmente financiado por Sernageomin. También se hizo nuevas campañas de terreno durante el período marzo 2016 – febrero 2017 (Bahamondes, Le Roux y Rivera). Se repitió el simposio en Lonquimay durante 29-30 de octubre del 2016, a pedido de la misma comunidad, en que se presentaron varias charlas, exhibiciones y talleres. En cuanto a los objetivos principales del proyecto del Terciario de Chile, se cumplieron plenamente con nuevas subdivisiones y correlaciones estratigráficas, estudios sedimentológicos, y datos que aportan al conocimiento del tectonismo andino durante el Terciario, en todas las áreas estudiadas. Por ejemplo, en el área de Bahía Inglesa se hizo una revisión completa de la estratigrafía terciaria, y un análisis geohistórico reveló que hubo una flexión oroclinal del dorsal Juán Fernández, que afectó el volcanismo en los Andes adyacentes. Los estudios de paleocorrientes y poblaciones de circones en la Cuenca Magallanes-Austral indicaron que la extensión noreste de la Península Antártida estuvo ubicada al este del Cabo de Hornos durante el Eoceno. Un análisis de más de 3.700 hojas fósiles en la sierra Baguales también indicó un fuerte episodio de solevantamiento de los Andes sur-patagónicos alrededor de 34 Ma, generando una sombra de lluvia al lado este de la cordillera. En cuanto al vínculo con el Centro de Excelencia de Geotermia Andina (CEGA), el trabajo de Viviana Pedroza en Lonquimay se enfocó en el reconocimiento de los reservorios más favorables para fluidos termales alrededor del volcán Tolhuáca, que ha sido el blanco principal de exploración geotermal en la zona. Viviana Pedroza (Magister), Nestor Gutiérrez (Doctorado) y Benjamin Bahamondes (Magister) ya tuvieron sus exámenes privados y tendrán sus exámenes públicos al fin de marzo y junio 2017, respectivamente. Huber Rivera (Magister) tendrá ambos exámenes durante marzo 2017. Se presentaron 2 ponencias en congresos geológicos en Santiago (Chile) y Montevideo (Uruguay) durante el 2016 (por un total de 9 en marco del proyecto), y se publicó 1 artículo en la revista Tectonophysics durante enero del 2017, sumando 4 artículos en revistas ISI hasta la fecha. Sin embargo, 2 artículos más ya han sido enviados a revistas internacionales y 3 artículos están en un estado avanzado de preparación. Memoristas Herman Rivas Muñoz (2016).

Here we studied new fossil chondrichthyans from two localities, Río de Las Minas, and Sierra Dorotea, both in the Magallanes Region, southernmost Chile. In Río de Las Minas, the upper section of the Priabonian Loreto Formation have yielded material referable to the taxa Megascyliorhinus sp., Pristiophorus sp., Rhinoptera sp., and Callorhinchus sp. In Sierra Dorotea, middle-to-late Eocene levels of the Río Turbio Formation have provided teeth referable to the taxa Striatolamia macrota (Agassiz), Palaeohypotodus rutoti (Winkler), Squalus aff. weltoni Long, Carcharias sp., Paraorthacodus sp., Rhinoptera sp., and indeterminate Myliobatids. These new records show the presence of common chondrichtyan diversity along most of the Magallanes Basin. The new record of Paraorthacodus sp. and P. rutoti, support the extension of their respective biochrons in the Magallanes Basin and likely in the southeastern Pacific. Keywords: Cartilaginous fishes, Weddellian Province, Southernmost Chile. RESUMEN.

We report combined detrital zircon U–Pb geochronology and (U–Th)/He thermochronology data and thermal modelling results that confirm delivery of both rap- idly cooled, first-cycle volcanogenic sediments from the Patagonian magmatic arc and recycled sedi- ment from deeply buried and exhumed Cretaceous foredeep strata to the Cenozoic depocentre of the Patagonian Magallanes basin. We have quantified the magnitude of Eocene heating with thermal models that simultaneously forward model detrital zircon (U–Th)/He dates for best-fit thermal his- tories. Our results indicate that 54–45 Ma burial of the Maastrichtian Dorotea Formation produced 164–180 °C conditions and heating to within the zircon He partial retention zone. Such deep burial is unusual for Andean foreland basins and may have resulted from combined effects of high basal heat flow and high sediment accumulation within a rapidly subsiding foredeep that was floored by basement weakened by previous Late Jurassic rifting.

ABSTRACT—This study presents the first record of Eocene birds from the western margin of southernmost South America. Three localities in Magallanes, southern Chile, have yielded a total of eleven bird remains, including Sphenisciformes (penguins) and one record tentatively assigned to cf. Ardeidae (egrets). Two different groups of penguins have been recognized from these localities. The first group is similar in size to the smallest taxa previously described from Seymour Island, Marambiornis Myrcha et al., 2002, Mesetaornis Myrcha et al., 2002, and Delphinornis Wiman, 1905. The second recognized group is similar in size to the biggest taxa from Seymour Island; based on the available remains, we recognize the genus Palaeeudyptes Huxley, 1859, one of the most widespread penguin genera in the Southern Hemisphere during the Eocene. The stratigraphic context of the localities indicates a certain level of correlation with the geological units described on Seymour Island.

The upsection loss of zircons derived from 23 the hinterland Paleozoic and Late Jurassic sources between ca. 60-44 Ma documents a major 24 shift in sediment routing due to Paleogene orogenesis in the greater Patagonian-Fuegian Andes.

BRANDON*, MICHAEL T. HREN**, JEREMY HOURIGAN***, ASTRID PACINI*, MARTHA G. COSGROVE*, MAYA MIDZIK*, RENE´ D. GARREAUD§, and CHRISTINE METZGER§§ ABSTRACT. Water isotopes are an important tool for reconstructing the amount of atmospheric lifting related to high topography in the geologic past. However, our capacity for meaningful interpretation requires understanding the climatic setting and isolating the influence of orography on water isotopes. Patagonia’s simple, steady climatology and location within the Southern Westerlies makes it an ideal setting for successful application of water isotopes to measuring topography through time. Here we use hydrated volcanic glass to construct a new record of the size of the Patagonian Andes during the Cenozoic. We also utilize a novel method for identifying the contribution of orography in regional climate records. Our results show that variation in the observed record can largely be explained by variations in climate. Thus we conclude that the mountain range has maintained a size similar to modern since at least Paleocene. This result is in agreement with geologic data, which constrain the bulk of the surface uplift of the Andes to the Cretaceous. The reconstruction of the Patago- nian Andes, which grew in the Cretaceous and remained high through the Cenozoic, is markedly different from the widely held view of Miocene formation of this mountain range. In particular, the topography appears to remain stable during the northward propagation and collision of offshore spreading centers.
