Subject: mineral id
I have the gabbros from the Eburnean from Ghana(~2120Ma old). They are not tectonized but suffered severe hydration and then low grade metamorphism producing epidote and sphene. In places cpx and plagioclase are still preserved as well as an orange mineral. Anyone with an idea of what the orange mineral can be. It is unlikely to be primary olivine.
