ⓘ 'Chlorite Group'

Localities:

Icaria, North Aegean, Greece
Atheras mountain, Icaria, Icaria, North Aegean, Greece

Description: Chlorite composition varies between corundophilite, pseudothuringite and ripidolite.

ⓘ Chloritoid

Formula: Fe²⁺Al₂O(SiO₄)(OH)₂

Description: Chloritoid is ironrich and exhibits strong zoning. Its Fetot content uniformly decreases from the core (1.856 a.p.f.u.) to the rim (1.585 a.p.f.u.), whilst the Mg content increases (0.051 to 0.146 a.p.f.u.).

ⓘ Gahnite

Formula: ZnAl₂O₄

References:

ⓘ 'Gahnite-Hercynite Series'

Description: SEM/EDS analyses have shown that spinel in the study area is a solid solution between hercynite (49 to 71 %mole) and gahnite (24 to 49 %mole) whilst the Mg component is negligible. Two groups of spinel can be distinguished in terms of the gahnite component: group “A” with gahnite content ranging from 24 to 38 %mole and group “B” with higher contents of the gahnite component (46 - 49 %mole). Chemical zoning was detected only in group “A” with crystals showing an enrichment in the hercynite component toward the rims whilst the reverse pattern is true for the gahnite component. Spinel with even higher gahnite content (as much as 62 %mole) has been previously reported (Ockenga 2000) in Ikaria.
