[QUOTE="Minelab Gold, post: 294337, member: 8504"] Good one Bjay, Looks to be sedimentary - when I first looked at the image looked to be a compressed sediment with an above medium concentration or iron oxide. But that should have broken down in the HCl Appears to be a claystone from the image. Pretty sure HCl doesnt attack or destroy the clay structure depending on concentration/minerals etc. Is the rock brittle? Shale is also a fine grained compacted clay silt or mud sedimentary rock - is there any layering? Nice find by the way [/QUOTE]
