| Popis: | The North Makran Domain in the Makran Accretionary Prism consists of an imbricate stack of Mesozoic Neo Tethyan ophiolitic and metaophiolitic units. The Deyader Complex is an important metamorphic unit of this Domain and includes tectonic slices of HP-LT blueschists derived from upper oceanic crust protoliths. The volcanic protoliths consist of basalts with Mg#=75.1-62.7, SiO2 = 41.59-48.02 wt%, and TiO2 = 0.79-1.53 wt%. Based on incompatible and REE contents and ratios, three geochemical types can be distinguished. Group 1 basalts show trace element compositions, and LaN/YbN and LaN/SmN ratios |
