| Abstract: | The Late Cretaceous Khabr-Marvast tectonized ophiolite is located in the middle part of the Nain-Baft ophiolite belt,at the south-western edge of the central Iranian microcontinent.Although all the volcanic rocks in the study area indicate subduction-related magmatism(e.g.high LILE(large ion lithophile elements) / HFSE(high field strenght elements) ratios and negative anomalies in Nb and Ta), geological and geochemical data clearly distinguish two distinct groups of volcanic rocks in the tectonized associat... |
