Reading all this I have a question for some real geologists out there. Maybe we could get the attention of rox or IRH or someone.
Are there any examples out there of strata where an unconformity exists such that it is a disconformity at one location and a nonconformity at another?
Where this might happen is where erosion had exposed an intrusion alongside the intruded upon layers. Subsequent deposition would have had to bury this unconformity. This would mean that the layers would have to be laid down, be intruded upon, the intrusion cool off, the intrusion erode, and THEN the unconformity be preserved by further burial.
This scenario would be TOTALLY devastating of a young earth, doubly so if the unconformity was angular.
Of course, biblical creationists are committed to belief in God's written Word, the Bible, which forbids bearing false witness; --AIG (lest they forget)
