After 200 years scientists finally crack the “dolomite problem”

A 200-year mystery is cracked as scientists finally grow dolomite—by learning how to wash away its flaws.

For more than two centuries, scientists tried and failed to grow dolomite in the lab under conditions thought to match how it forms in nature. A recent study has finally changed that. Researchers from the University of Michigan and Hokkaido University in Sapporo, Japan succeeded by developing a new theory based on detailed atomic simulations. Their work solves a long-standing geological puzzle known as the "Dolomite Problem." Dolomite is a widespread mineral found in iconic locations such as the Dolomite mountains in Italy, Niagara Falls and Utah's Hoodoos. It is abundant in rocks older than 100 million years, yet it is rarely seen forming in more recent environments.

For 200 years, scientists have failed to grow a common mineral in the laboratory under the conditions believed to have formed it naturally. Now, a team of researchers from the University of Michigan and Hokkaido University in Sapporo, Japan have finally succeeded, thanks to a new theory developed from atomic simulations. Their success resolves a long-standing geology mystery called the "Dolomite Problem." Dolomite—a key mineral in the Dolomite mountains in Italy, Niagara Falls, the White Cliffs of Dover and Utah's Hoodoos—is very abundant in rocks older than 100 million years, but nearly absent in younger formations. "If we understand how dolomite grows in nature, we might learn new strategies to promote the crystal growth of modern technological materials," said Wenhao Sun, the Dow Early Career Professor of Materials Science and Engineering at U-M and the corresponding author of the paper published today in Science. The secret to finally growing dolomite in the lab was removing defects in the mineral structure as it grows. When minerals form in water, atoms usually deposit neatly onto an edge of the growing crystal surface. However, the growth edge of dolomite consists of alternating rows of calcium and magnesium.
