Github repository for Wilcots, J., Bergmann, K.D., Gilbert, P.U.P.A, Cross, A., Nanoscale crystal fabric preserved in dolomite ooids at the onset of the Ediacaran Shuram excursion. This repository contains analytical data on dolomite fabrics in ooids formed during the onset of the Shuram excursion from the uppermost Khufai Formation in the Huqf region, Oman. Two additional dolomite samples were compared from the Buah and Birba Formations. Samples were prepared as thin sections (0.25 μm thickness) and epoxy-mounted blocks. EBSD, SEM-EDS, and EPMA samples were polished with colloidal silica and carbon-coated prior to analysis, PIC samples were polished to 50 nm with Al₂O₃ and platinum-coated before analysis. Acid etching was completed on polished thin sections with 10% HCl for 30 seconds before SEM analysis. XRD analysis was completed with small powder quantities with a zero-background silicon sample holder.
