Mineral Chemistry of Chlorite Replacing Biotite from …
1996. An alkaline gabbro from the Brome complex, in Quebec, contains abundant biotite that is highly enriched in Ba and Ti. A bulk-mica sample has been analyzed for structural H 2 O, FeO and Fe 2 O 3, and by Fe and Ti K-edge and Ti L-edge X-ray absorption spectroscopy to provide information on the valency and coordination states of Fe and Ti.
