ABSTRACT
This paper presents results obtained during exploration of gold-rich quartz veins in low mountain, humid environments of the Colombian Andes, South America. Spontaneous potential profiling was used to evaluate strike-slip duplex structures and to locate gold-rich veins in extensional zones of a vein system. Six days of total fieldwork helped to model the deposit, and provided ideas on where to continue exploring with trenches. Similar exploration techniques may be applied to greenstone belt-hosted mesothermal shear zones and some epithermal base-metal deposits.

Key-words: electricity, epithermal mineralization, geophysics, gold, humid environments, mineral exploration, natural potential, spontaneous potential, veins.


RESUMEN
Este documento presenta resultados obtenidos durante la exploración de vetas auríferas de cuarzo en ambientes húmedos tropicales de baja montaña de los Andes Colombianos, Sur América. Se usaron perfiles de potencial espontáneo para evaluar duplexas de cizalla y ubicar vetas ricas en oro en zonas extensionales de un sistema de vetas. En total, seis días de trabajo ayudaron a modelar el yacimiento, y dieron ideas sobre dónde continuar explorando con trincheras. Técnicas de exploración similares pueden aplicarse a sistemas de cizalla mesotermales alojados en rocas verdes, y a algunos yacimientos epitermales de metales base.

Palabras-clave: ambiente húmedo, duplexa cizalla, electricidad, exploración minera, geofísica, geología estructural, mineralización epitermal, oro, potencial espontáneo, potencial natural, S.P., sistema de vetas, tropical, veta.
