A Pseudomorphosis is the change of a mineral in the course of crystallization. Here, crystals of Calcite were initially formed, then a change (chemical, pressure, element) having taken place in the « pocket », Silica took over and in its turn of Quartz came to crystallize. However, the Calcite crystallisation has retained its appearance, but it is now Quartz.
