I would really love to see the picture that you refer to in "Modern Physical Geography." I will be looking for a copy of it I assure you. The type of concentric shells you refer to are an indication of deposition, not erosion. Deposition bands can be seen in minerals like agates which display successive periods of deposition with pauses between. A style of banding can also be seen in some sedimentary or metamorphic rocks, but not in the pattern shown in the article.
Your assertion that the people who discovered this are idiots is truly saddening. You seem to base this on the fact that these structures show a characteristic that you have seen in one picture in one book. This is truly ignorant, so please come up with some real evidence before you attack the people. I highly doubt that your "geologist" friends will find anything funny about the article, especially if you use the argument that you presented here.
