Abstract

The non-mineralized mafic rocks from several localities of the Letovice crystalline complex were studied. Concentrations of PGE were detected (Ir up to 4.38 ppb, Ru up to 7.29 ppb, Rh up to 0.91 ppb, Pd up to 1.81 ppb, Pt up to 12.41 ppb), Ni (up to 2,240 ppm), Cu (up to 497 ppm) and Cr (up to 5,479 ppm) and compared with results from non-mineralized rocks of the HSV-1 structural borehole at Svitavy and other ophiolites. Various metal ratios in the Letovice samples indicate close geochemistry with other world ophiolite complexes.
