Estimados Colegas

Espero este e-mail los encuentre bien

Los contactamos con el objetivo de invitarlos a someter resumenes a la Sesión técnica "Nuevas Avances en Evaluación de Impacto Ambiental en Colombia" que se realizara bajo el XVI Congreso Colombiano de Geologia.

El XVI Congreso Colombiano de Geología, se llevará a cabo en la ciudad de Santa Marta los días 28 de agosto al 01 de Septiembre de 2017. La fecha limite de sometimiento de resumenes es el 15 de Marzo. Informacion de como someter su resumen la encuentran en el siguiente link http://sociedadcolombianadegeologia.org/congreso2017/

Descripcion de la sesion tecnica.

El rápido crecimiento de la población mundial durante el último siglo ha llevado al incremento desproporcionado de las actividades productivas y económicas. Estas actividades impactan el medio ambiente terrestre y marino (sistemas agua, aire, biota y tierra) de manera directa o indirecta y en diferentes magnitudes y duraciónes. La complejidad de los factores antrópicos y naturales que afectan el medio ambiente local y global ha hecho de la evaluación del impacto ambiental de las actividades humanas una tarea relativamente difícil. Dicha evaluación ha requerido multi-disciplinareidad y el uso de diversas técnicas analíticas, modelos matemáticos/estadísticos, y cuadros regulatorios legales complejos. Para esta sesión técnica invitamos contribuciones enfocadas en los últimos avances tecnológicos y científicos implementados en actividades de evaluación de impacto ambiental, tanto a nivel terrestre como marino. Contribuciones enfocadas en los últimos avances de modelos matemáticos/estadísticos usados en la evaluación de impacto ambiental son altamente valoradas. Finalmente, invitamos de manera especial contribuciones que se enfoquen en estudios del cuadro regulatorio ambiental Colombiano, y en la comparación de este con cuadros regulatorios a nivel regional y global. Tambien invitamos contribuciones enfocadas en innovacion en educacion ambiental y desarrollo sostenible, asi como en trabajos enfocados en remediacion de problemas ambientales.

Cordiales saludos

Two new fully funded PhD positions at the Department of Earth and Atmospheric Sciences University of Houston


Two fully funded PhD positions are available at the Department of Earth and Environment of the University of Houston starting in January 2015. Details can be found below.

1. Investigating the effects of ocean acidification and de-oxygenation during the Triassic Jurassic Biologic Crisis.

The PhD project will focus on the sedimentologic, stratigraphic and geochemical characterization of several carbonate-black shale successions worldwide (Colombia, Peru, Italy, Austria). The candidate must demonstrate interest on geochemistry laboratory work as he/she is expected to perform stable Ca and Sr isotope analyses in carbonates as well as Mo and U isotope analyses in black shales. The candidate must also demonstrate strong stratigraphic analysis skill as well as extensive fieldwork experience. Funding is initially granted for 4 years (includes tuition fee and stipend) and extension depends on scientific and academic performance.

2. Sedimentologic and Geochemical Characterization of the Cretaceous Oceanic Anoxic Events in tropical epiric seas, implications for the occurrence of unconventional hydrocarbon sources and past environmental change.

This PhD project will focus on the sedimentologic and inorganic geochemical characterization of the Cretaceous sedimentary record along the Middle and Upper Magdalena basins, Colombia. The aim of the research is to differentiate the effects of regional tectonics, sea level change and climate on the stratigraphy of these mature basins, as well as their influence on the regional occurrence of conventional and unconventional oil sources and reservoirs. The project also aims on quantifying how bad the environmental conditions were during different OAEs in a tropical epiric sea. Funding is initially granted for 4 years (includes tuition fee and stipend) and extension depends on scientific and academic performance.

Interested student should have at least a 5 years BSc degree in geology or related areas and must have defended their BSc thesis. Candidates with MSc and experience in sedimentology, straigraphy and geochemistry will be preferred.

For more info about the project please contact Prof. Juan Carlos Silva [email protected] [email protected] . More info about the University of Houston Geology PhD program can be found at

A doctoral applicant will have earned a Master’s degree or have completed 30 semester hours of graduate credit, and submitted scores from the General GRE examination (verbal, quantitative, and analytical writing; advanced GRE is recommended but optional).

New Geochemical instrumentation

A new portable XRF has been acquired by the Carbonate Sedimentology and Geochemistry Group. The new Tracer III SD XRF from Bruker will allow rapid non destructive geochemical analysis of rocks, soils, archeological artifacts (pottery), among other materials. The tracer III SD, developed by Bruker and NASA, will be of great use for shale gas exploration and chemostraigraphic analysis at reasonable price and rapid sample throughput. The Tracer III SD is a powerful geochemical tool for rapid assessment of contamination in soils and even non geologic materials (i.e. toys, paints, etc)
