Mg isotope fractionation during microbial dolomite formation in the Khor Al‐Adaid sabkha, Qatar

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
Modern sabkha sediments from southern Qatar show ca. 1‰ Ca isotope fractionation between pore water, organic matter and dolomite, supporting microbial mediation. In contrast, minimal Mg isotope fractionation and inorganic‐like dolomite δ26Mg indicate that microbial influence is indirect, expressed through subtle pore water shifts driven by Mg ...
