Major and trace element mineral compositions of carbonated serpentinites and listvenites from Oman Drilling Project Hole BT1B (Semail Ophiolite, Oman)

We present a petrographic and geochemical dataset acquired on carbonated serpentinites and listvenites from Oman Drilling Project Hole BT1B (Semail Ophiolite, Oman). The overarch aim of data acquisition was to characterize elemental mobility, rock precursor contribution, and changes in fluid compositions during the carbonation sequence converting serpentinized peridotites to carbonated serpentinite, and ultimately listvenites. This dataset includes: i) petrographic information (mineral abundance, occurrence of microstructures), and ii) major and trace element mineral compositions measured by EMP and HR-LA-ICPMS.
