Abstract
The high-Al podiform Loma Baya chromitite deposits occur hosted within an ultramafic massif representative of ophiolitic mantle produced in a back-arc basin near to the westernmost edge of the Guerrero Composite Terrane, SW Mexico. Such conclusion is drawn from the tholeiitic (i.e., back-arc basin basalt) affinity of the parental melts of the chromitite, deduced from major and trace element distribution in chromite, and the nature of the platinum-group elements mineralization.
