Abstract
The ophiolitic massif of Kahnuj (600 km(2)) consists, from bottom to top, o f layered gabbros, isotropic gabbros and ouralite gabbros, agmatites of dio ritic to plagiogranitic composition, a sheeted dyke complex and lastly a ba saltic pillow lava unit. Amphiboles from gabbros were dated (K-40-Ar-40 age s) between 156 and 139 Ma and the agmatites are nearly contemporaneous. Pot assic granitic veins dated at 93-88 Ma are related to the development of th e Ganj are complex, (C) 2001 Academie des sciences / Editions scientifiques et medicales Elsevier SAS.
