Palladium, platinum, and rhodium concentrations in mafic and ultramafic rocks from the Zhob Valley and Dargai complexes, Pakistan

December 31, 1980

The Zhob Valley and Dargai complexes, Pakistan, consist of harzburgite and dunite tectonites containing chromite deposits, pyroxenite, wehrlite, and gabbro. Both are ophiolite complexes. Palladium, platinum, and rhodium were found in concentrations of up to 170, 200, and 22 parts per billion, respectively. Average concentrations for both complexes and all rock types collected are 28 ppb palladium, 33 ppb platinum, and 9 ppb rhodium. The Pt:Pt+Pd ranges from 0.41 to 0.67 and averages 0.57. The concentration levels and ratios of these metals are similar to other alpine ultramafic bodies that have been analyzed by modern techniques.
