Abstract
"The paper point out the volcanogene and sediment-hosted base metal deposit from the Colombian cordilleras have been considered in the light of tectonogenic models for these deposit types, based upon the recent re-interpretation of the geology and tectonic assembly of the Northern Andean Block by Cediel and Cáceres and Cediel. Numerous distinct propitious metallogenic settings containing important but subexploredbase metal mineralisation are manifest as a result of the tectonic evolution of this northern-most sector of the Andes. Some examples include like a) Central African Cu (U) Belt - type mineralisation within the back-arc region of the early– middle Paleozoic Cordillerantype Quetame Orogeny, b) numerous SEDEX and Sediment-Hosted Zn (Pb-Ag) and Cu (Ag) styles of mineralisation associated with various phases of continental and continental margin rifting during the late Paleozoic to Mesozoic Bolívar Aulacogen, and c) various Cu-Zn-Pb (Au, Ag) Volcanogene Massive Sulphide manifestations associated with intra-oceanic magmatic arc development and accretionary tectonics during the Meso-Cenozoic Northern Andean Orogeny.
