A mapping approach for the investigation of Ti–OH relationships in metamorphic garnet

Garnet is a nominally anhydrous mineral that can incorporate several hundreds of ppm H2O in the form of OH groups, where H+ substitutes for cations in the garnet structure. To understand the effect of such small amounts of H2O on the physical and chemical properties of garnet, it is essential to determine where and how the OH groups are incorporated into the mineral structure. We investigated correlations between major and minor element maps...
