Hi Jeffrey.

There were a number of threads on the TB forum about rock strata that I was involved in. One of the best findings I think was http://sedimentology.fr which showed that conforming strata likely were all laid down at the same time/s probably by flooding. Some of the disconformities, nonconformities and unconformities may have been deposited at nearly the same time too.

Can you say offhand whether the boundaries you mention are conformities, or dis-, non-, or un-comformities?

Can you explain briefly what you use to determine the ages that you mention? Do you have a link to something on that?

I don't care if you want to call stars and planets the same thing, but I define stars as bodies that radiate a lot of energy and planets as bodies that don't radiate so much. And I don't think there's a need to challenge people about that.
