[MIS02-15] Geophysical Logging of Crust-Mantle boundary at Oman Ophiolite
Keywords:oceanic crust, upper oceanic mantle, borehole geophysics, alteration
The Samail ophiolite exposed in Oman is one of most well-known surface exposures of the exhumed lowest part of the oceanic crust and upper part of mantle.
The Oman Drilling Project (OmanDP) drilled 12 holes at 7 sites in this ophiolite from 2016 to 2018, and has conducted a comprehensive borehole geophysical survey as logging operation in most of these holes in 2017 and 2018. The data acquired include: electrical resistivity, spectral gamma ray, magnetic susceptibility, full waveform sonic, optical / acoustic / resistivity borehole wall imaging. The extensive logging operation also includes high-definition spectroscopy measurements that contribute to further geochemical investigations. The outline of these datasets and our preliminary analysis will be presented.
