Epidote Thin Section

Epidote in epidosite plane polars epidote in epidosite crossed polars epidote in unakite plane polars epidote in unakite crossed polars.

Epidote thin section. Streak is white to gray. Although commonly light yellow green in thin section it may be colorless. The octahedral chains are linked by silicon in sio 4 and sio 7 groups sharing oxygen ions with aluminum.

Optic axis dispersion is usually strong with v r clinozoisite or r v epidote distinguishing features. Epidote is characterized by its green color and one perfect cleavage. Epidote in epidosite ppl.

Oblique to cleavage in pseudo hexagonal sections otherwise straight on cleavage in prismatic section. Epidote in thin section thin section gigapans. Clinozoisite epidote thin section photomicrographs are taken in plane polarized light and cross polarized light and can easily be recognized under the microscope.

Plane cross polarized light field width is 1 2 mm. In one third of the octahedral groups al 3 is surrounded by four o 2 and two oh. There you ll find addi.

The epidote structure consists of octahedral alo6 groups sharing edges to form continuous chain parallel to b axis.
