There has been mistakes concerning the belief on how sedimentary rock was deposited during earth’s history. Back in 2007, Schieber, Southand and Thaisen came up with a a mechanism which challenged the existing consensus theory.
Mudstone is made up of very fine particles, only microns in diameter. It is believed that these tiny particles slowly settle down in the calm of the water to the bottom where over periods of time it builds up. Then it compacts and compresses. This is what the secular consensus believes mudstone comes from.
Now what these geologists discovered about mudstones is quite remarkable, and should have creationists standing up in glee. Progress in science is very exciting! What this experiment found was the fact that mudstones can be deposited under more energetic conditions, requiring a reappraisal of many geologic records.
The paper was published in science which states…
“Mudstones make up the majority of the geological record. However, it is difficult to reconstruct the complex processes of mud deposition in the laboratory, such as the clumping of particles into floccules. Using flume experiments, we have investigated the bedload transport and deposition of clay floccules and find that this occurs at flow velocities that transport and deposit sand.”
“Deposition-prone floccules form over a wide range of experimental conditions, which suggests an underlying universal process. Floccule ripples develop into low-angle foresets and mud beds that appear laminated after postdepositional compaction, but the layers retain signs of floccule ripple bedding that would be detectable in the rock record.”
“Because mudstones were long thought to record low-energy conditions of offshore and deeper water environments, our results call for reevaluation of published interpretations of ancient mudstone successions and derived paleoceanographic conditions.”
Interpretations of a quiet, slow, and calm mudstone deposit virtually affects most areas in science. Geologists study mudstones for clues about depositional history. Oceanographers study mudstones for clues about plankton cycles and patterns. Biologists study fossils in mudstones for clues to evolutionary history. Even planetary scientists study mudstones for clues about the orbital history of the Earth.
Now fast forward to this month where these same geologists continue to show sedimentary rock being created in flowing or turbulent water. New ways have been invented to observe in more detail what is going on in turbulent muddy water which shows how mudstones are formed.
In their latest science paper published this month, states the following…
“Fine-grained sedimentary rocks (grain size <62.5 µm), commonly known as shales or mudstones, are the most abundant sedimentary rock type. They contain the bulk of geologic history recorded in sedimentary rocks (Schieber, 1998), and are a key element in organic-matter burial, the global carbon cycle, and the hydraulic isolation of groundwater resources and waste materials.”
“Economically, they are an important source of hydrocarbons, minerals, and metals (Sethi and Schieber, 1998). They are susceptible to weathering due to their clay content, and so often appear quite homogeneous to the casual observer. Because of this, they are much more poorly understood than other types of sedimentary rocks, in spite of their importance.”
“An enduring notion about deposition of muds has been that they are deposited mainly in quiet environments that are only intermittently disturbed by weak current activity (e.g., Potter et al., 2005). Flume experiments have shown, however, that muds can be transported and deposited at current velocities that would also transport and deposit sand (Schieber et al., 2007).”
“Deposition-prone floccules form over a wide range of experimental conditions, regardless of the exact parameters that drive flocculation in a given experimental run. Floccule ripples, ranging in height from 2 to 20 mm, and spaced from centimeters to decimeters apart, migrate over the flume bottom and accrete into continuous mud beds at streamwise velocities from 0.1 to 0.26 m/s.”
Even though the latest experiment was conducted by those who believe in evolution, it clearly shows the theory of tiny particles slowly settling to the bottom, producing uniform, homogeneous sediment layers is the wrong conclusion while it verifies the vary essence of the affects and evidence for a global flood recorded in the Bible. One cannot wait for more progress in this area when future updated tools for observation verifies even more.
