San Felipe resulted from the weathering of mantle peridotites of the Cretaceous Camag\u00fcey ophiolites. In this study, a geochemical and mineralogical characterization of two profiles (83 and 84) from the San Felipe deposit has been performed by XRF, ICP-MS, quantitative XRPD, oriented aggregate mount XRD, SEM, FE-SEM, and EMPA. Core 83, with a length of 23 m and drilled in the central part of the plateau, presents a notable concentration of cryptocrystalline quartz fragments and a rather poor content of NiO, averaging 0.87 wt.%. Core 84, which is 12 m long and drilled at the border of the plateau, lacks silica fragments and presents a higher NiO content, averaging 1.79 wt.%. The smectite structural formulae reveal that they evolve from trioctahedral to dioctahedral towards the top of the laterite profiles. Quantitative XRD analyses indicate that smectite is a dominant Ni-bearing phase, accompanied by serpentine and minor chlorite. Serpentine, as smectite, is enriched in the less soluble elements Fe3+, Al, and Ni towards the top of the profiles. Core 83 seems to have been affected by collapses and replenishments, whereas core 84 may have remained undisturbed.<\/p>\n\n\n\n<p>----------------------------------------------------------------------------------------------------------<\/p>\n\n\n\n<p><strong>To Cite this article:<\/strong> Tauler, E., Gal\u00ed, S., Villanova-de-Benavent, C., Chang-Rodr\u00edguez, A., N\u00fa\u00f1ez-Cambra, K., Khazaradze, G., &amp; Proenza, J.
