Unconformities Not Conforming to Secular Geological Views
So, when rock layers that have assigned ages are separated by non-depositional or erosional surface, that surface is called an unconformity. There are four of them, with words that are unlikely to be found in casual conversation: nonconformity, angular unconformity, disconformity, and paraconformity. The last is the most troubling for uniformitarian geologists.

Scientists have speculations, reasoning, models, and so forth based on the presumption of an old earth. Errors are made, and some facts are neglected. What we really have is geology that is best explained by the rapidly-flowing water and catastrophic tectonics of the Genesis Flood. What are unconformities and what do they mean to
