Cratón Amazónico como posible origen de la ocurrencia aurífera tipo placer en el Oriente Colombiano

Abstract

Through a complete work of collecting mineralogical, geochemical, geochronological data from previous studies, together with the compilation of geological interpretations made in Proterozoic rocks in southeastern Colombia, a preliminary evaluation is made about the possibility that these rock units may host gold mineral depositsthat have been hosted during the early stages of formation of these bodies, to identify possible primary sources that are contributing secondary gold manifestations in placers on the riverbanks.
