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 tecton...

ion and re-representation. COMPARING ANALOGIES AND MODELS The terms model and analog are often used interchangeably by both scientists and educators (Hesse, 1966, 2000; Duit, 1991). Comparing analogs and models based on the preceding review of the characteristics of each suggests that this interchangeability is valid when analogies are based on relational characteristics. The term "representati...
