Rock 365 : Day 68 : Caliche Conglomerate #365photos


Day 68 : Working from home so a boulder from the back garden collection today. It is from the Devonian of Pembrokeshire, Wales and is red siltstone with calcium carbonate nodules. I'm uncertain if the calcium carbonate is a 'primary' caliche or if they have been reworked to form a conglomerate.
