  • To date, covariance of carbonate and organic carbon isotope records has been assumed to denote fidelity of the original signal. This study shows that post-depositional alteration can create strong correlations, raising doubts about the use of correlated records to imply important changes in past global carbon cycling.

  • Microbial extracellular polymeric substance networks promote accumulation of Mg-rich clay which in turn serves as a substrate for carbonate precipitation in saline lakes and ponds of Salar de Llamara, according to microstructural observations of microbial mat samples.
