I am not a sedimentologist, but I think that clay is a type of mud, usually
of a finer grain. Mud possibly covers silt and sand as well. As a cave
surveyor I do not think that I can tell a difference, so would would not
particularly want different symbols, but I suspect there are lot of people
out there who do. I have tended to use minus signs for mud and dots for
sand. But I most probably should be using dots for all of it
