Genesis and geodynamic significance of chromitites .
Abstract Chromitites from Orhaneli and Harmancik ophiolites (Bursa, NW Turkey) are mainly associated with dunites. They occur as banded and lenticular bodies showing massive and disseminated textures and are composed of magnesiochromite grains characterized by the following composition: Cr 2 O 3 = 58.30–61.19 wt.%, Al 2 O 3 = 8.32–10.03 wt.% and TiO 2 = 0.14–0.21 wt.%.
