Mineral–microbe interactions play important roles in environmental change, biogeochemical
cycling of elements and formation of ore deposits. Minerals provide both beneficial (physical …

Carbonate minerals contain stable isotopes of carbon and oxygen with different masses
whose abundances and bond arrangement are governed by thermodynamics. The clumped …

Crystals grow in supersaturated solutions. A mysterious counterexample is dolomite CaMg
(CO3) 2, a geologically abundant sedimentary mineral that does not readily grow at ambient …

Abstract Otavi Group is a 1.5–3.5-km-thick epicontinental marine carbonate succession of
Neoproterozoic age, exposed in an 800-km-long Ediacaran− Cambrian fold belt that rims …

Dolomite genesis is a century-old mystery in sedimentology. To reveal the mechanism of
dolomite genesis, two core problems need to be addressed. The first is the origin and …

Over the past decades, the burial realm, the most prolonged and arguably the least well‐
understood diagenetic environment, has received significant research attention. Despite …

Dolomite can form as a major mineral component of marlstones and limestones and is an
important sink for magnesium in the marine environment. Dolomite is widely distributed in …

In order to explore Cryogenian seawater chemistry and its underlying controls, we present
an integrated study of iron speciation, major and trace elements, and carbon isotopes of Mn …

Abstract The Ediacaran Period (ca. 635–541 Ma) witnessed the earliest paleontological
evidence for macroscopic animals (ie, Ediacara biota) and geochemical observations of the …

The lithium isotope composition (δ7Li) of seawater records important information on the
evolution of the carbon and silicon cycles over geologic time. Here we report δ7Li values in …
