Dunite rock. Polarised light micrograph of dunite,an ultramafic (low silica content) rock consisting nearly entirely of olivine. Here,the olivine (coloured due to the polarisation),forms a granular,densely packed structure. Dunite also usually contains some chrome-spinel,which is opaque and thus black here in this thin section. This image has been obtained using cross-polarised light (or 'crossed nichols') | |
