Title

Petrography and Geochemistry of ophiolitic basalts from Marivan-Palangan region (Zagros, western Iran)

Pages

  75-96

Abstract

 Magmatic evolution, partial melting and petrogenesis of the basaltic rocks from Marivan-Palangan ophiolite suite, Zagros suture zone, western Iran have been studied. basaltic rocks mostly exhibit pillow structures and have remarkable outcrops in the crustal succession of the Marivan-Palangan ophiolite. Based on petrographic and geochemical criteria, two distinct rock types are recognized. Regarding the chemical classifications, both types are basalt. The results of CIPW norm calculations reveal their olivine tholeiitic (abyssal tholeiitic) nature. They also belong to the tholeiitic magma series close to the transitional type. The high Ti contents of the basalts are indicative of the High-Ti affinity of the ophiolites. Fractionation of variable amounts of olivine, plagioclase and clinopyroxene is inferred from variation diagrams, particularly for the type two rocks. Although both rock types resemble the E-MORB on the multi-element diagrams, they are remarkably distinct regarding the HREE and MREE contents. Partial melting models suggest that the basalts have been originated after 5-25% (type 1) and 15-25% (type 2) partial melting of a spinel lherzolite mantle source. Besides, Sm/Nd, Ce/Sm, Sm/Yb and La/Yb ratios of the samples are close to an EMII-type enriched mantle; that may be indicative of contribution of EMII-type components to the petrogenesis of the magmas. It is concluded in this research that variable degrees of partial melting of a spinel peridotite mantle source, combined with the contribution of EMII-type components generated the enriched nature of the ophiolite-related basalts in this part of the Neo-Tethyan realm.
