Abstract
Description
El sector estudiado en la Provincia de Vélez (Dpto. de Santander, Colombia), presenta rocas sedimentarias marinas del Cretácico Inferior (Formaciones Cumbre, Rosablanca, Paja y Tablazo), deformadas durante las distintas fases de la Orogenía Andina, las cuales dieron lugar a la formación de estructuras tales como: Los Anticlinales La Chirle y Vélez, El Sinclinal de Vélez, Las Fallas El Guamito, Peña Negra y La Hervedora, entre otras.La presencia localizada de sectores con pizarrosidad (“slaty cleavage”); venas con rellenos de asfaltita brechificada, calcita, agregados de mica potásica, esfalerita y clorita; bandas de albititas y sulfuros; entre otras manifestaciones presentes en el área de influencia de las Fallas El Guamito y Peña Negra, se interpretan como productos asociados a procesos de interacción fluido-roca. Por consiguiente, estos sectores son considerados los de mayor interés para la exploración de nuevas mineralizaciones hidrotermales (esmeraldas?).
The studied sector in the Vélez Province (Dpto. of Santander, Colombia), presents lower Cretaceous marine sedimentary rocks (Cumbre, Rosablanca, Paja and Tablazo Formations), deformed during the different phases of the Andean Orogeny, which gave rise to structures such as: The Chirle and Vélez Anticlines, The Vélez Syncline and The Guamito, Peña Negra, Hervedora Faults, among others.The presence of sectors with slaty cleavage; veins filled by brechoid asphaltites, calcite, K-mica, agregates sphalerite and chlorite, albitites and sulphide bands, among others manifestations, in the influence areas of The Guamito and Peña Negra Faults, are interpreted as products associated to fluid-rock interaction processes.Consequently, these sectors are considered as the greater interest for the exploration of new hydrothermal mineralitatios (emeralds?).
