CALERO GOMEZ, Kevin; ALBACURA CHUQUIN, Laura; SOLANO-YEPEZ, Stalin  and  VITERI SANTAMARIA, Francisco. Modelos de depósitos tipo VHMS para las divisiones de la Cordillera Real: Alao y Salado. Figempa [online]. 2021, vol.11, n.1, pp.2-11. ISSN 2602-8484.  https://doi.org/10.29166/revfig.v11i1.2664.

The Cordillera Real comprises autochthonous and allochthones land accreted to the continent, represented from west to east by thelithothectonic divisions Guamote, Alao, Loja, Salado and Zamora Divisions. This work describes the possible vhms (Volcanogenic Massive Sulphide) deposits present in the Alao and Salado divisions, based on previous studies of petrology, petrography and evolution of these divisions. The parameters used to compare vhms model types with possible deposits of the divisions are: geological environment, tectonic framework, nesting rocks, associated rocks, textural and mineralogical characteristics of massive bodies, alteration and geochemical characteristics. In this way, it can be established that the deposits of the Peltetec Unit are not associated with a vhms deposit as there are differences with respect to lithology and geochemistry. In contrast, the model associated with a Kuroku-type VHMS deposit coincides with the characteristics of a VHMS.

Keywords : Cordillera Real; vhms; Evolution; Beshi Type; Salado.
