Island Arc Magamatism
This 50 slide PowerPoint presentation introduces the basic structural facets of an island arc system. Magma series (tholeiitic, alkaline, calc-alkaline) and differentiation within magma series are related to the major elements. Other trends in magma series (spatial, temporal, trace element, isotope) are presented. Petrogenesis of magmas is illustrated in terms of mantle flow, rate of subduction and age of the subducting slab and subduction zone. Pressure-temperature-time paths are used as instructive tools. This resource is part of the Teaching Petrology collection.
