These plagioclase and clinopyroxene mineral chemical and Sr isotope data come from Unit 10, Rum Layered Suite, NW Scotland. They underpin a publication entitled 'Rapid crystallisation of precious metal-mineralised layers in mafic magmatic systems', to be published in Nature Geoscience in 2020.

Scanned and annotated thin sections, in plane-polarised and cross-polarised light. Derivative statistical data for mineral grainsize and spatial distribution.

Electron backscatter diffraction data for cumulates from the Skaergaard Intrusion of East Greenland. 12 samples from the Skaergaard Intrusion: 9 from the Layered Series, and 3 from the trough layering. Layered Series samples have a prefix LS; Trough layer samples have a prefix TB.

Data produced from NERC Grant NE/L000059/1 - IODP Exp 335 report which is open access and includes all the observations and other data generated on the Expedition. http://publications.iodp.org/proceedings/335/335toc.htm
