Young earth explanations for Angular Unconformities

The Pennsylvanian Fountain formation lies on precambrian igneous and metamorphic rock west of Denver, a nonconformity. Excellent place to look at that contact is in Red Rocks Park. Further to the east the Pennsylvanian is deposited on top of Mississippian rocks and there is a disconformity, with the Missippian showing a weathered upper surface and a paleosoil. These rocks are in the subsurface so you can't directly look at them. I know this from dipmeter and formation microimaging data and I also cored it when I worked for Phillips Petroleun in the 80s.

Here is a link to a angular unconformity to nonconformity in California.

Percy,

Google "spheroidal weathering images", now look at Edge's photo. The lower pinkish rocks are the granite, do you see the spheroidal weathering in the granite now? The granite was being weathered chemically but the weathered material was not being removed.

To weather a granite this deeply requires a substantial amount of time. It is an interesting photo because it is a picture of an unconformity that clearly shows a prolonged period of weathering before the later deposition. If everything weathered has been removed this is not as clearly shown.
