DTG curves (wt.%/°C) for phyllosilicate (a), Fe-(oxy)hydroxide (b) and carbonate (c) standard minerals. At <200 °C, the phyllosilicates and Fe-(oxy)hydroxides suffer significant mass loss due to dehydration of both structural and adsorbed terrestrial H2O. Further mass loss due to dehydration and dehydroxylation occurs between 300 and 800 °C for phyllosilicates and 200 and 400 °C for Fe-(oxy)hydroxides. Carbonates decompose and produce CO2 between 600 and 800 °C
