Calling On Present and Future Creation Geologists

Dolomite which was discovered 200 years ago and was named after French geologist Déodat Gratet de Dolomieu, has remained a problem using the evolutionary framework.


“More than 90 percent of dolomite is made up of the mineral dolomite. It was first described scientifically in the 18th century. But who would have thought that the formation of this mineral is still not fully understood, although geologists are aware of large deposits of directly formed (primary) dolomite from the past 600 million years.”

“The process of recent primary dolomite formation is restricted to extreme ecosystems such as bacterial mats in highly saline lakes and lagoons. “As these systems are very limited in space, there is an explanation gap for geologists for the widespread presence of fossil dolomite,” explains Dr. Stefan Krause, Geomicrobiologist at GEOMAR | Helmholtz Centre for Ocean Research Kiel.”

What has been discovered here is that dolomite requires vast quantities of bacteria. In the lab, researchers were able to get dolomite to crystalize under conditions that prevail in the current oceans but this raised a new problem…

“Evidence of primary dolomite formation by a process as common as microbial sulphate respiration under conditions that currently prevail in the seabed, provides new insights into the reconstruction of fossil dolomite deposits. But why are large-scale deposits from primary dolomite no longer formed at the ocean floor?”

“Here we are still faced with a puzzle,” says Professor Tina Treude, head of the Working Group at GEOMAR.  “One possibility is that massive primary dolomite can form particularly during times when large quantities of organic matter in the seabed are degraded by sulfate-respiring bacteria. Such conditions exist when the sea water above the seafloor is free of oxygen. In Earth’s history, several such oxygen-free periods have occurred, partly consistent with time periods of intensified dolomite deposition.”

The tentative explanation which relies on conditions that at first were described as those that currently prevail, yet apparently do not prevail, because large-scale deposits of dolomite are not forming now on the ocean floor! While admitting to it as a “puzzle” using an assumption in the unobservable past, dolomite remains a gap after 200 years of research.

This is a great topic for research for creation geologists who can examine the data in terms of using global flood conditions.  They can’t do any worse than what we are observing with secular geologists who learn more about it, but create more questions than answers for the past 200 years.
