Sedimentologist Guy Berthault was one of a team who made an important discovery regarding how the world’s sedimentary layers were deposited. These geological strata are clearly-defined beds of sedimentary rock that often have the appearance of bands or stripes of alternating or repeating layers. Most people have noticed them in cliffs, where they are often seen in side view. Grand Canyon comes to mind, where bold horizontal layering in the sides of the canyon is a major visual feature.
Geologists once thought that all such layers formed upwards. This conventional view of layer formation was one of the three principles of stratigraphy identified by creationist geological pioneer Nicolaus Steno (1638–1686). However, today the typical way this is explained is that sand, silt, and clay settled to the bottom of a placid lake or sea, and accumulated over eons of time. Eventually, a significant…
