Without you this never would have happened. iii ABSTRACT The emplacement of tholeiitic magmas along two NE-SW trending rift zones is the dominant mechanism of crustal accretion on Iceland. Small vol...

ABSTRACT Igneous rock forming minerals carry valuable information from the deep earth that is not directly accessible at surface. Each mineral represents physico-chemical conditions which various magmatic processes have occured over a wide range of depths upper mantle to shallow crustal levels. These are cryptically inscribed in whole-rock and compositions (e.g. major elements, trace elements i...

The eruptions of Campi Flegrei (Southern Italy), one the most studied and dangerous active volcanic areas world, are fed by mildly potassic alkaline magmas, from shoshonite to trachyte phonotrachyte. Petrological investigations carried out in past decades on rocks provide crucial information for understanding differentiation processes its magmatic system. However, compositional features a palim...
