Abstract

Abstract only refereed. We present a detailed statistical study of the distribution of platinum-group minerals in a set of strongly serpentinized chromitites from the Sagua de Tanamo mining district (Mayari-Baracoa Ophiolite Belt, eastern Cuba). On the basis of the distribution, textures and chemical nature of the platinum-group minerals we show how platinum-group elements firstly concentrate as primary platinum-group minerals during the magmatic stage, then were mobilized during serpentinization in an ocean-floor scenario when these primary platinum-group minerals became unstable.
