Spinel lherzolite nodules of an U, Cretaceous mafic dyke in the Villány Mts. were studied. The xenolith consists of olivine, enstatite, Cr-diopside and Cr-Fe spinel as primary phases. No garnet or plagioclase is present. Alteration of the rock resulted in breakdown of olivine and formation of calcite, limonite and clay minerals. These processes can geochemically be followed by a significant loss of Mg and Ni as well as a gain of Ca relative to an average spinel lherzolite.
