Galena


Galena is ductile with a strong cleavage and is not expected to be a good host for fluid inclusions.

Galena samples from various deposits do show good decrepitation, but interpretation of the decrepitation temperature is uncertain and may be dominated by post entrapment recrystallization events.  The woodcutters and Broken Hill deposits have both been deformed and they show much higher decrepitation than the Sullivan deposit which is less deformed. Perhaps the decrepitation intensity is indicative of post-entrapment deformation and recrystallisation events. If so, then most of the Tunisian samples seem to have been recrystallized.  (A separate discussion of all samples from Tunisa is here)
