Figure F15. The Ti and Al relations (cations per formula unit) in clinopyroxenes. Ti vs. total Al contents; Ti/Al vs. Mg/(Mg + Fe2+) ratios; Ti vs. AlIV contents. Fe2+ was estimated from charge balancing the cations. The groups of gabbros are as for previous figures. Pyroxenes with <10 wt% CaO are not included.
