Devilline, posnjakite and brochantite

Crystalline crusts between light blue and greenish blue in color covering areas of alteration.
The crusts are usually accompanied by chalcopyrite and usually cover quartz and calcite.

The analysis using Raman and XRD has made it possible to determine that it is a mixture of three species: devilline, brochantite and posnjakite, which explains the color variation in the crusts.
