Microstructural measurements of mafic igneous rocks (NERC Grant NE/N009894/1)
Measurements of the shape and size of plagioclase and olivine grains in a suite of dolerite dykes and sills. The olivine data refer to the family of sills forming the Little Minch Sill Complex where exposed on the Isle of Skye, while the plagioclase work also includes a range of sills and dykes from all over the world. Measurments of dihedral angles at junctions between two grains of plagioclase and one of pyroxene, again in dolerites from dykes and sills, and also from the Rustenburg Suite of the Bushveld Layered Intrusion in South Africa.

Data Quality
Measurements of grain size and shape were made from detailed photomicrographs of thin sections. Dihedral angles were measured from thin sections using a universal stage mounted on an optical microscope.
