Description

Thin tabular colourless lustrous schieffelinite associated with glassy transparent ottoite on brown chlorargyite. 

The identification was made by Raman spectroscopy and SEM-EDS. The Raman data clearly shows transitions in the sulfate area matching well with the quantification of the EDS data. Ottoite was confirmed by SEM-EDS & Raman (a reference from the Bird Nest Drift mine was used).
