Collector notes
A barite pseudomorph is a mineral specimen where barite (BaSO₄) has been completely replaced by another mineral (such as quartz, agate, jasper, or pyrite) while preserving the original crystal shape, structure, or rosette form. Through a process like metasomatic replacement or interface-coupled dissolution precipitation, fluids rich in silica or other minerals dissolve the original barite molecule by molecule and deposit a new mineral (like quartz/agate) in its exact footprint.
