A pilot study, carried out by the British Geological Survey and INGEOMINAS, on the gold placers of a 1, 200 〖Km〗^2 area of the basins of the Timbiqui and Napi Rivers (Cauca Department), has located new gold prospects in alluvial and bedrock environments.
Field mapping based on photogeology and heavy mineral survey has shown the bedrocks to consist of an arc – related volcano – sedimentary oceanic basin sequence related to a Mesozoic – tertiary subduction zone and containing products of explosive andesitic volcanism associated with deep – water marine sediments bearing Eocene to middle Oligocene fossils.
The andesitic rocks were intruded by a quartz diorite body of possible Neogene age and near the contact zone the volcanic rocks are of very pale colours and argillised with a low pH (about 4) and are rich in kaolinite and sulphates; pan concentrates from streams crossing this zone contain barite, fluorite, carbonate and sulphides, and the wallrocks appear to represent the caprock at the upper levels of an epithermal system.
La primera fase (1986-1988) de un proyecto de capacitación bilateral de la Administración Británica de Desarrollo de Ultramar y el Gobierno colombiano ha delineado un modelo para la exploración sistemática de oro en el flanco costero pacífico densamente boscoso de la cordillera occidental de los Andes colombianos. Un estudio piloto, llevado a cabo por el British Geological Survey e INGEOMINAS, sobre los placeres de oro de un área de 1, 200 〖Km 2 de las cuencas de los ríos Timbiqui y Napi (departamento del Cauca), ha localizado nuevas perspectivas de oro en aluvión y ambientes de roca madre.
El mapeo de campo basado en fotogeología y levantamiento de minerales pesados ha mostrado que los cimientos consisten en una secuencia volcánica sedimentaria relacionada con una zona de subducción mesozoica y terciaria que contiene productos de vulcanismo andesítico explosivo asociado con sedimentos marinos de aguas profundas con Eoceno a los fósiles del Oligoceno medio.
Las rocas andesíticas fueron intruidas por un cuerpo de diorita de cuarzo de posible edad neógena y cerca de la zona de contacto las rocas volcánicas son de colores muy pálidos y argilizadas con un pH bajo (alrededor de 4) y son ricas en caolinita y sulfatos; los concentrados de pan de los arroyos que cruzan esta zona contienen barita, fluorita, carbonato y sulfuros, y las rocas
