UPRIGHT TEXTURAL AND COMPOSITIONAL VARIATION IN THE MASSIVESULPHIDES DEPOSIT OF LA COLORADA MINE (SALTA). La Colorada mine is aMassive Sulphides deposit of Ordovician age. It is located in Cobres (Salta, Argentina), atan average altitude of 3.900 m a.s.l. Ore is made up of the metallic association Fe-Cu-PbZn with traces of Au, Ag and Bi. Mineralogy includes dominant pyrrhotine, accompanied bysphalerite, galena, chalcopyrite, and minor amounts of electrum-associated arsenopyrite.Currently, it is classified as a Kuroko type VMS deposit. This contribution aims to providedata about the vertical variation of the textures, mineralogical composition and hydrothermalalteration registered in a ~40 m thick mineralized sequence registered in a drilling core ofLa Colorada deposit.
