Introduction
Geologist specializing in metamorphic petrology and geochemistry. My research focuses on understanding the Earth's history through mineral analysis and isotopic dating techniques. I've gained expertise in various geochronological methods and currently apply this knowledge to geological mapping projects.

The core of the Santander Massif in the northern Andes of Colombia is dominated by migmatitic gneisses with a < 1.71 Ga protolith and were affected by continuous interactions of oceanic plates to the west and the northwestern corner of the South American continental plate. The exposed metamorphic core of the massif offers a unique opportunity to un...
Determining the crystallization and cooling ages of detrital zircons from ancient sedimentary rocks or modern river sediments is a powerful method for tracing the sediment provenance and exhumation of orogenic mountain belts. Here, we
present a study of the U–Pb and fission–track dating of detrital zircons from: (1) the
sedimentary cover units of t...
The roughly 600 km long Central Cordillera of Colombia shows a varied tectonic, magmatic, and exhumation history, despite the reasonably homogenous appearance concerning topography, outcropping lithologies, and strike. Here we show with new geo-thermochronological data the thermal evolution of the southern Central Cordillera since the Early Jurassi...
The formation of metamorphic zircon after baddeleyite is
a well-known reaction that can be used to date the metamorphism of igneous
silica-undersaturated rocks. By contrast, metamorphic minerals formed after
igneous zirconolite have rarely been reported. In this paper, we document
metamorphic titanite + zircon pseudomorphs formed from the metamorph...
The Sveconorwegian orogen in Scandinavia and the Grenville orogen in Canada are both remnants of large and hot orogens that formed part of the supercontinent Rodinia around 1 billion years ago. Formerly deeply buried portions of crust in these orogens are exposed and offer insights into the tectonic dynamics of the basement within large orogens. Th...
Trace element mapping of garnet from a sillimanite-bearing migmatitic gneiss has been used to document the crystal evolution during the two distinct tectonometamorphic events. The major elements are homogeneously distributed, whereas the zoning patterns of heavy-REE suggest multi-stage garnet growth.
Granitic rocks are durable materials sought after for the production of road and railroad aggregates. Granitic bedrock commonly, however, includes gabbroic components, which may enhance or decrease the aggregate performance. This study evaluates the variation in resistance to fragmentation (Los Angeles value, LA) and wear/abrasion (micro-Deval valu...
Granitic rocks constitute a global raw material key asset for aggregate production. Their technical performance is, however, highly variable and knowledge on the aggregate functionality of granites in different geological settings is incomplete. This study investigates systematic variations in resistance to fragmentation (Los Angeles value) and wea...
This study focuses on the metamorphic recrystallization process steered by the influx of hydrous fluids and associated deformation in low-silica rocks that contain primary baddeleyite and (rare) zirconolite.
The Geology of Colombia book provides an updated background of the geological knowledge of Colombia by integrating the most up–to–date research covering paleontology, biostratigraphy, sedimentary basin analysis, sedimentology, sequence stratigraphy, stratigraphy, geophysics, geochronology, geochemistry, thermochronology, tectonics, structure, volca...
En este trabajo se presenta la relevancia de la implementación de la norma NTC ISO/IEC
17025:2005, norma internacional que establece los requisitos generales para la
competencia en la realización de ensayos (1)(4), en los ensayos de geocronología por
la técnica de Espectrometría de Masas con Plasma Acoplado Inductivamente con ablación láser (LA-ICP...
The continuous search for mineral resources such as gold, copper and base metals etc. requires a refined understanding of the thermal evolution and exhumation history of potential exploration targets, as only ore deposits can be exploited that have been exhumed to the surface or near to the surface. In order to better understand the exhumation hist...
This paper presents the first results of the implementation of the U-Pb dating laboratory at the Servicio Geológico Colombiano (Colombian Geological Survey) using the LA-ICP-MS analytical technique for U-Pb dating. This geochronological method is based on the radioactive decay of the isotopes of Uranium (238U/206Pb and 235U/207Pb) in order to be us...
This paper presents a historical description of the implementation process of the Low Temperature
Thermochronology laboratory at the Colombian Geological Survey. The laboratory is focused
on thermochronological dating of apatites and zircons with the fission track method. Here
we explain the applied methodology, the results of the inter-calibration...
El Complejo Aleluya está localizado en la parte central de la Cordillera Central de Colombia y su investigación es de relevancia para conocer la distribución espacial y temporal de las mineralizaciones asociadas a los basamentos cristalinos en esta zona. Corresponde a una sucesión plegada de rocas metamórficas, de protolito sedimentario carbonatado...
El estudio de inclusiones fluidas asociadas al sistema hidrotermal-magmático del Volcán Nevado del Ruiz permitió conocer en detalle aspectos característicos de los fluidos involucrados en la evolución del sistema geotérmico. Para ello se seleccionaron muestras de la parte más profunda de tres pozos de gradiente térmico que fueron perforados en la z...
A fluid inclusions study in the Nevado del Ruiz volcano hydrothermal system allowed to characterize fluids involved in the evolution of the geothermal system. Fluid inclusions hosted in quartz, plagioclase and carbonate from samples of the deepest parts of three thermal gradient wells were analyzed to understand fluid-rock interaction. Fluid inclus...
El Neis de Bucaramanga es la unidad litodémica más antigua del basamento ígneo-metamórfico del Macizo de Santander, las tres grandes fajas (occidental o faja Bucaramanga, central y oriental) que han sido descritas comprenden una sucesión de neises pelíticos y semipelíticos intercalados con capas delgadas de rocas calcosilicatadas, mármoles, neis ho...
