This paper reviews the distribution of platinum-group minerals in ophiolitic chromitites. Our data and literature data, obtained by in-situ investigation of polished sections and techniques of mechanical separation [hydroseparation (HS), or combining electric pulse disaggregation (EPD) plus HS], are contrasted. Finally, in-situ textural data are used as platform criteria to compare the different proposed models that attempt to explain the origin of the platinum-group mineral assemblages found in ophiolitic chromitites.
