Akasakaite-La

[edit]

Akasakaite (La) is a mineral that has the formula (CaLa)(AlAlMn2+)O[Si2O7][SiO4](OH)[1], colour dark brown, vitreous, has a specific gravity 4.050[1], crystal system is monoclinic, and lays in the allanite group of Epidote supergroup.The location of this type is at Mogurazawa mine, Kiryu City, Gunma Prefecture, Japan.[1] Named in accordance with the rules of the epidote supergroup.

Akasakaite-La is a new mineral discovered in the allanite-group.

Akasakaite-Ce

[edit]

Different to Akasakaite-La, this element's formula is (CaCe)(AlAlMn2+)O[Si2O7][SiO4](OH)[2]. It is all the same to Akasakaite-La except of its specific gravity, 4.055[2].

Root

[edit]
