Formula:

(CaLa)(Fe3+AlMn2+)O[Si2O7][SiO4](OH)

Crystal System:

Monoclinic

Name:

Named in 2014 by Mariko Nagashima, D. Nishio-Hamane, N. Tomita, T. Minakawa, and S. Inaba in honor of Masahide Akasaka (b. 1950), professor at Shimane University, Japan, for "his outstanding contributions to mineralogy, especially to the study of rock-forming minerals occurring in Mn–Fe ore deposits and the natural and synthetic epidote-supergroup minerals." The name includes a prefix and a suffix indicating constituent elements according to the epidote-supergroup nomenclature.

Allanite Group of the Epidote Supergroup. Ferriakasakaite-(La) has a new combination of dominant cations at A1(Ca) and M3(Mn2+), which are the key sites to determine a root name for epidote-supergroup minerals.
