Sedimentary Structures which Disprove Young Earth and Flood Geology

It has been suggested that I start a new topic to discuss in greater depth how biogenic sedimentary rocks such as the White Cliffs of Dover are conclusive proofs of an Old Earth - expanding on my post here:http://EvC Forum: How can Biologists believe in the ToE? -->EvC Forum: How can Biologists believe in the ToE?thread proposed by jar (http://EvC Forum: How can Biologists believe in the ToE? -->EvC Forum: How can Biologists believe in the ToE?)and seconded by Lithodid-man (http://EvC Forum: How can Biologists believe in the ToE? -->EvC Forum: How can Biologists believe in the ToE?)

It is ok to link to the post which got this started but you should at least copy the particular on topic material here so that this thread stand on it's own two feet.Do that and it should be promotable. If you can put in more please do.
