Calcite

Wherever there is a crack or cavity in the rocks, they tend to be filled with mineral-rich waters from which crystals form. The most common mineral in our rocks is calcite, as is the case here. Calcite looks quite like quartz, which also fills cavities in the rock, but quartz is very much harder and will scratch glass whereas calcite won’t.
