what kind of breccia or conglomerate is this? sorry for the lighting but we have a lack of sun here and my phone does not photograph well without sunlight dos i use a lamp instead.
oke thank you for the explanation here are some better photo's got some sun finally.Breccias and conglomerates have two parts, the clasts and the matrix holding everything together. It looks like the clasts in your rock are quartz. It also looks like the matrix is a softer material. Conglomerates have rounded clasts. The clasts were moved and weathered before being locked in a matrix. The clasts in breccias haven’t been moved or weathered and are angular and sharp. On some breccias, the matrix is quartz, which forms a very hard rock overall. Your clasts look half way between rounded and sharp angular so I’m not sure what I would call it. Maybe polishing an area would show the clasts better.
