What Biostratigraphic Continuity Suggests About Earth History, Kurt P. Wise, Donna Richardson
Proceedings of the International Conference on Creationism
If the present world contains sediments generated in the global Flood described in the Bible, we would expect a distinctive paleontological uniformity at both the beginning and the end of the Flood. Populations of organisms both before and after the Flood would be expected to persist at any particular locality for a significant period of time. Many of the same species would be expected to persist across every depositional time boundary at most localities in the world throughout both the pre-Flood and post-Flood worlds. During the Flood, of the species deposited in more than one depositional level, it would not …

Radiohalos Through Earth History – What Clues Can They Provide Us?, Andrew A. Snelling
Proceedings of the International Conference on Creationism
Radiohalos are a physical record of radioactive decay that occurred in granites and metamorphic rocks through earth history. They are the result of damage to the host crystals by α-particles produced in the 238U decay chain (Snelling 2000). Normally 238U radiohalos are produced. However, there are also radiohalos produced by the three isotopes of Po (218Po, 214Po and 210Po) that are generated towards the end of the 238U decay chain. Because their half-lives are so fleeting (3.1 mins, 164 µsec, and 138 days, respectively), the existence of these Po radiohalos has been “a …
