Combining data from several of the Perseverance rover’s spectroscopic sensors offers a more accurate means to classify carbonate minerals that may hold hints of ancient life.
A new study suggests that carbonatite metasomatism, not silicate metasomatism as previously thought, was dominant prior to the removal of the North China Craton in the early Cretaceous.
The Nullarbor Plain has been relatively untouched by geological forces, leaving traces of the continent’s deep past.
Spreading olivine on beaches could accelerate ocean uptake of carbon dioxide and potentially limit climate change. The concept and execution still face some scrutiny from scientists.
Microbes from wells as deep as 90 meters created organic carbon at a rate that overlaps with some nutrient-poor spots in the ocean.
Using data collected from Hawaii to Alaska, a new study sheds light on calcium carbonate cycling in the ocean, an understudied component of the global carbon cycle.
Geochronologists are finding fresh approaches to familiar methodologies, especially by zapping rocks with lasers to tackle classic Precambrian problems.
Studies of Earth’s critical zone have largely focused on areas underlain by silicate bedrock, leaving gaps in our understanding of widespread and vital carbonate-dominated landscapes.
Sedimentary structures from evaporative coastal environments indicate carbonate saturation, offer insight in mid-Mesozoic ocean chemistry and potentially even earlier times.
A community effort finds that carbonate standards eliminate the interlaboratory differences plaguing carbonate clumped-isotope thermometry studies.
