Introduction
Research geologist at the Technological development Centre for the Colombian Emeralds. Graduated from the National University of Colombia with a focus on economic geology and geochemistry, mainly in Colombian emerald deposits. I belong to the research group (Atlas Research Group), in addition, in 2019 I founded the Emerald Student Chapter. I have experience in different analytical techniques such as: Raman spectroscopy, fluid inclusions analysis, petrography, among others.

Colombian emeralds are widely recognized for their unique gemological and geological features; The first one involves color, which depend on the proportions of their minor and trace elements. The latter is associated with its genesis, which implicates hydrothermal brine fluids affecting the sedimentary host rock. Thus, to propose an emerald fingerp...
In Colombia, emerald deposits are sediment-hosted in two parallel belts (Western and Eastern Emerald Belt). Host rocks are calcareous mudstones and limestones of Lower Cretaceous age. The emerald genesis is associated to the flow and mixing of basinal and evaporate derived fluids; a process that took place in organic-rich beds, the leached and rele...
The Colombian emerald deposits are confined in both flanks of the eastern Cordillera. Those deposits are referred to as; the eastern emerald belt (EEB) and the western emerald belt (WEB). The formation conditions of the Colombian emeralds are unique in the world considering the differences in the host rock and the hydrothermal fluids. They are host...
La Pava es una mina perteneciente al distrito minero de Muzo, uno de los siete distritos reconocidos en la producción esmeraldífera colombiana, su mineralización ocurre en venas y brechas que atraviesan la Formación Muzo y se caracteriza por tres estadios mineralizantes definidos por las asociaciones de albita-microclina, calcita-fuchsita-esmeralda...
