Dolomite Problem : 200-year-old geology myst

<p>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 pulled it off, thanks to a new theory developed from atomic simulations.</p> <p>Their success resolves a long-standing geology mystery called the &quot;Dolomite Problem.&quot; Dolomite&mdash;a key mineral in the Dolomite mountains in Italy, Niagara Falls, the White Cliffs of Dover and Utah&#39;s Hoodoos&mdash;is very abundant in rocks <a href="https://pubs.acs.org/doi/full/10.1021/acsearthspacechem.2c00078#"><u>older than 100 million years</u></a>, but nearly absent in younger formations.</p> <p>The lessons learned from the Dolomite Problem can help engineers manufacture higher-quality materials for semiconductors, solar panels, batteries and other

Dolomite crystals require cycles of saturatio

<p>Addressing the long-standing &ldquo;dolomite problem,&rdquo; an oddity that has vexed scientists for nearly 200 years, researchers report that dolomite crystals require cycling of saturation conditions to grow. The findings provide new insights into how dolomite is formed and why modern dolomite is primarily found in natural environments with pH or salinity fluctuations. Dolomite &ndash; a calcium magnesium carbonate &ndash; is one of the major minerals in carbonate rocks, accounting for nearly 30% of the sedimentary carbonate minerality in Earth&rsquo;s crust. However, despite its geological abundance, dolomite does not readily grow under laboratory conditions, hindering the study of the mineral. For two centuries, scientific efforts have failed to precipitate dolomite in the laboratory near ambient conditions. The apparent contradiction between the massive deposits of dolomite in nature and its inability to grow even in supersaturated solutions under ambi
