They tend to reject the Genesis Flood and explanations from creationist scientists who offer differing explanations of observed evidence regarding geologic history — no catastrophism allowed here, Hoss. (Despite their biases, some geologists do allow for some catastrophes in Earth history). The huge catastrophe of Genesis Flood actually fits observed data far better than the offerings of secular scientists.
Research by the Institute for Creation Research further undermine uniformitarian geology.
ICR’s ongoing Column Project (an analysis of over 500 drilling-core and outcrop samples from across North America) has revealed surprising results that smash entrenched uniformitarian thought. The rocks continue to support the biblical account of one worldwide Flood.To drill down into this article, click on "Grappling with Megasequences".
The main area of interest concerns the six megasequences that comprise most of the fossil-bearing strata on Earth. Megasequences are defined as packages of sedimentary rock bounded top and bottom by erosional surfaces, with coarse sandstone layers at the bottom (deposited first), followed by shales, and then limestone at the top (deposited last). The corresponding size of the sedimentary particles is also thought to decrease upward in each megasequence ... The megasequences are interpreted as representing the depth of the sea at the particular time each one was laid. The base sandstone layers of each megasequence are believed to represent the shallowest sea level, the shale a little deeper water environment, and the limestone the deepest water environment in each sequence. By tracking these changes in rock types, geologists are able to define each megasequence.
