Abstract Miocene strike‐slip tectonics was responsible for creating and closing short‐lived (ca. 6 Ma) passages the emergence of isolated topography in Northern Andes. These geological events likely influenced migration and/or isolation biological populations. To better understand paleogeography hinterland foreland regions Andes, we conducted a source‐to‐sink approach Magdalena Basin. This basin is located between Central Eastern Cordilleras Colombia contains an ample record, which includes...
Extensional and flexural basins can evolve through multiple stages under the same plate tectonic regime over tens of millions years. The Cretaceous evolution Colombian Andes is characterized by shifts between contractional extensional tectonics. upper response to these changes recorded in sedimentary rocks along Western, Central, Eastern cordilleras, their adjacent basins, including Upper Magdalena hinterland basin. We integrated field observations, petrography, geochronology,...
Abstract The West Burma Terrane (WBT) is a small terrane bounded to the east by Asian Sibumasu Block and west Indo‐Burman Ranges (IBR), latter being an exhumed accretionary prism that formed during subduction of Indian oceanic lithosphere beneath Asia. Understanding geological history WBT important for reconstruction closure Tethys Ocean India‐Asia collision. Currently there are major discrepancies in proposed timings collision between with both India Asia; whether collided or Asia first...
Abstract The tropical Northern Andes constitutes a great area to explore the interaction of tectonics and climate on evolution orogenic topography, as they are tectonically active, have steep gradients in relief precipitation, were less affected by Quaternary glaciations than high‐latitude mountains. This study combines new published thermochronology along ∼500 km Eastern Cordillera Colombia what controls rates Miocene Pliocene exhumation, including: (1) variations late Cenozoic...
Marginal basins are the result of extensional tectonics along convergent margins. These include an early stage seafloor spreading that, in some cases, is followed by tectonic inversion and deformation basin formation a new magmatic arc front. The Early Cretaceous South American Plate caused development multiple pre-Andean back-arc marginal continental margin. were inverted during onset Andean orogeny Late Cretaceous. For instance, Northern Andes, remnants this history found Central...
Abstract In the worldwide context of rising salinity issues in agriculture, it is important to understand crop responses stress. Currently, standing as second largest oilseed crop, canola ( Brassica napus L.) entices continued research focus on such aspects. Thus, this study investigated genotypic variation seedling emergence characters under Two growth chamber experiments were conducted diverse genotypes (10 each winter and spring types) at six levels (0, 2, 4, 6, 8, 10 dS m −1 EC)....
New field data, geochemical analyses and zircon U-Pb LA-ICP MS data were obtained on plutonic volcanic rocks of the Mocoa Batholith Saldaña Formation in southern Colombia Putumayo region.Results suggest that activities are closely related to a common magmatic history.This volcano-plutonic association presents well-defined LILE LREE enrichment negative Nb Ti anomalies characteristic continental arcs.Volcanic crystallized between 180-186 Ma as revealed by geochronology.The activity is...
El bioma mioceno de La Venta (Colombia): un siglo investigación y perspectivas para el futuro. En los depósitos fosilíferos Venta, en Colombia, se registra una las biotas fósiles más ricas la porción tropical Suramérica, lo que representa oportunidad excepcional estudiar efectos cambios climáticos del Mioceno evolución clados existentes extintos ecosistema latitudes bajas. Los vertebrados terrestres acuáticos son mayormente representados; mientras registros plantas e invertebrados menos...
Plutonic rocks typically have negligible matrix porosity and permeability. However, fractures mineral alterations create storage space flow pathways that turn plutonic into fluid reservoirs. Despite significant hydrocarbon discoveries, naturally fractured reservoirs in been poorly studied. In most Colombian basins, the crystalline basement has undergone multiple deformational events is thrust over Cretaceous to Cenozoic source reservoir of conventional petroleum system. This structural...
Abstract The Jurassic magmatic record in the southern Colombian (Northern Andes) includes numerous subduction-related I-type calc-alkaline granitoids with diverse structures and textures, formed two main episodes at ∼195 to 165 Ma ∼165 145 Ma. We provide new insights into mineral chemistry, estimates of intensive parameters petrogenetic processes 12 plutonic occurrences region, grouped 4 petrographic associations. Primary assemblages include labradorite-to-oligoclase, alkali feldspars,...
Abstract Dispersion of low‐temperature thermochronologic data from nine samples collected on a deformed paleosurface preserved the Cuevas range (Central Andes) can be exploited to unravel complex thermal histories. The yielded that have both intersample and intrasample dispersions; set includes apatite fission‐track ages (180–110 Ma), mean track lengths (11–13 μm), helium (10–250 zircon (180–348 Ma). We ran inverse history models for each sample reveal spatial variations Miocene reheating...
Estratigrafía de un Lagerstätte neotropical del Mioceno medio (localidad La Venta, Colombia). El Konzentrat-Lagerstätte la localidad Venta registrado en el Grupo Honda contiene información invaluable sobre respuesta biótica a los cambios climáticos Transición Climática Mioceno. Su registro fósil ha sido estudiado durante casi siglo y ofrece una las mejores ventanas ecosistemas terrestres Neotrópico Neógeno. Hemos compilado todos estudios publicados y, utilizando correlación gráfica mapa...
Abstract Marked along‐strike changes in stratigraphy, mountain belt morphology, basement exhumation, and deformation styles characterize the Andean retroarc; these have previously been related to spatiotemporal variations subduction angle. We modeled new apatite fission track (U‐Th‐Sm)/He data from nine ranges located between 26°S 28°S. Using published data, we constructed a Cretaceous Pliocene paleogeographic model that delineates four‐stage tectonic evolution: extensional tectonics during...
