For such a common observation, it is amazing that it hard to find YEC publications that deal, in a straight forward way, with angular unconformities.

OK, I'll bite, what in the hell does this mean?

Figure out how what is pictured in the first post of this thread was formed. That will answer your question since the answer is not compatible with YEC models.

Everything is compatible with YEC models. YEC models aren't subject to annoying facts or logic.

An angular unconformity is <a href="http://www.xrefer.com/entry/611708" target="_blank">a discordant surface of contact between the deposits of two episodes of sedimentation in which the older, underlying strata have undergone folding, uplift, and erosion before the deposition of the younger sediments, so that the younger strata truncate the older.</a>

In the picture above, the underlying strata were deposited, then tilted about 90 degrees by tectonic forces, and eroded into a nearly flat surface before the overlying sediments were deposited. There is also a basal conglomerate at the unconformity, a layer of rock containing blocks of rock eroded from the underlying strata, which indicates that the underlying strata were lithified before deposition of the overlying strata. Another good example of an angular unconformity is that found in the Grand Canyon region at the contact of the Grand Canyon Supergroup and the Cambrian Tapeats Sandstone.

Angular unconformities are a problem for flood geologists because the lithification and erosion cannot be plausibly fit into a single flood year.

Oh, I see....I couldn't tell what that picture was....I thought it was a rug or something at first. Now that I look more closely, I can see the trees up top.

Anyways, I think the YECs could come up with something regaurding an inital sedimentation from the first part of the flood which was then tilted when all the continents and mountains did all of their sliding around. Erosion and further sedimentation during the next year w/ the world covered in water. No problem here.

True. But it is far more profound with angular unconformities. Not to mention it is something that can be easily explained to and accepted by the man-on-the-street. Heck many ordinary people could figure it out themselves if simply nudged slightly in the right direction.

This is a subject where the YECs are vulnerable. In the end, it might be more profitable (prophetable?) to talk about unconformities than a lot of talk about radiometric clocks which a bit abstract to many people.

Nothing is more profound than with GOD'S WORD!

Easier than God done it?

I dunno. I used to think that most ordinary people would see a problem with YECism anyway.

What subject isn't?

Could be. But if they think GOD'S WORD overrides anything, it won't matter what you talk about.
