Final Epithet
Staurolithites peristrefomeno Varol, in prep.
Basionym
Staurolithites peristrefomeno Varol, in prep.
Etymology
From the Greek peristrefomeno, meaning ‘rotated’, referring to the strongly rotated cross relative to the axis of the loxolith.
Description
Species of Staurolithites are characterised by a zeugoid outer wall, a very narrow zeugoid inner wall, and a strongly rotated right-angle cross that supports a distal process.
Optical Properties
In plan view under XPL, the outer wall is in constant extinction because the optic axis (c-axis) is perpendicular to the microscope stage, whereas the inner wall and the cross display white interference colours.
