Q1
If it's true, that Earth mantle is the only source of Ru, Rh, Pd, Ir, Os, Pt in Earth crust - it's interesting to establish the phase forms of these elements (PGE) in "primary mantle matter": garnet and spinel peridotites (lherzolites, hartzburgites without plagioclase) in such ultramafic high-pressure complex as Ronda (South Spain) or Marocco's analogues.

Finding the PGE minerals in "primary mantle matter" may show the special features of PGE separation in Earth crust in comparison with PGE mineralization which is typical for Alpine-type complexes, layered complexes and etc.

Our question is: "Can somebody collaborate with us, obtain samples and start the work"?
