Black axinite , This material
Viewed with the microscope, contained a dense aggregation of randomly oriented greenish gray flakes ; the abundance of the inclusions absorbed light and made the axinite appear black. Raman analysis of the inclusions identified them as clinochlore. Gaines et al. (1997) reported that axinite-(Fe) may rarely be replaced by clinochlore-chamosite, but in this case the inclusions appeared syngenetic with the host.
