Hi all,
I'm currently digging a small possibility in South Wales. It is completely full of mud and rocks but there appears to be a layer of ironstone within the fill. So I'm wondering about how this occurs and if anyone on here can offer any insights. Would it have been deposited from iron mineral-rich waters at some point when the sediments were being laid down? Or, would it have been washed in as small rocks from somewhere else?
Just curious about how such layers may originate but also if it is possible to infer anything about what the cave system may have been like before becoming blocked and filled with sediments.
TIA
