@ARTICLE{, author = {}, title = {Geochemistry and petrogenesis of basaltic flows in the Nain-Dehshir ophiolites}, volume = {16}, number = {4}, abstract ={Diabases, pillow lavas and basaltic flows in the Nain-Dehshir ophiolites are marked with flat to slightly depleted pattern in REE chondrite-normalized diagram and are characterized by depletion in HFSE and enrichment in LILE. This geochemical behavior can be considered for lavas erupted in arc-related environments. Clinopyroxene in these rocks shows low content of TiO2 and resemble those found in island-arc tholeiites. These characteristics are consistent with back-arc formation during middle to upper Cretaceous, due to the oblique subduction of Neotethyan Ocean along the active continental margin of the central Iranian block. }, URL = {http://ijcm.ir/article-1-611-en.html}, eprint = {http://ijcm.ir/article-1-611-en.pdf}, journal = {Iranian Journal of Crystallography and Mineralogy}, doi = {}, year = {2009} }
