Abstract:
The Glen Doll and Juan Jorge Complexes are two contrasting late Caledonian calc-alkaline plutons intruded into Middle Dalradian metasediments at the northern end of Glen Clova, in the Angus district of Tayside, Scotland. The Glen Doll Complex (12 km squared) constitutes a wide range of rock types from olivine gabbro, through diorite to adamellite. The bulk (> 80%) of the succession consists of heterogeneous hornblende- and pyroxene-bearing diorites. Partially assimilated rafted metasedimentary xenoliths, are common in the intermediate rock types. The basic rocks are cumulates which display wall-parallel layering. Mineralogical variation displays a transition from pyroxene-dominated anhydrous assemblages to amphibole-dominated assemblages. The diorites by contrast display floor-parallel layering and typically contain cumulate magnetite and ilmenite. Petrographic and mineralogical data suggests that fractionation played an important role in the evolution of the cumulate rocks.
