tectonomagmatic characteristics of the etive igneous complex, south west scotland

the etive igneous complex has intruded into dalradian and moine meta-sedimentary rocks in devonian. main rock types of the complex are granodiorite, monzodiorite, monzogranite, granite and diorite. geochemical studies show that the magmas were of high k calc-alkaline, i-type and metaluminous nature. application of discriminant diagrams to the etive rocks indicates a possible within-plate tectonic setting for the complex. considering the magma type and trace element geochemistry along with behaviour of studied samples on tectonomagmatic discriminant diagrams, contributions of subduction related materials and materials with within-plate affinities are likely in generation of the etive igneous complex.
