“…Chromian spinel (Cr-spinel) is a common accessory mineral in igneous mafic and ultramafic rocks. Mantle section of ophiolite may host accumulation of Cr-spinel as podiform and/or stratiform bodies (e.g., Augé, 1987;Lorand and Ceuleneer, 1989;Gauthier et al, 1990;Borisova et al, 2012;González-Jiménez et al, 2014;Arai and Miura, 2016;Arai, 2021). These bodies are usually separated from the host harzburgite by a dunite envelope of variable thickness from a few centimeters to several meters (e.g., González-Jiménez et al, 2014;Arai and Miura, 2016).…”
