Laguna Fuente de Piedra: An example of a dolomite factory recording ~50,000 years of depositional and paleoclimatic evolution

The Depositional Record, Volume 12, Issue 1, February 2026.
This study characterises carbonate mineral precipitation mechanisms and their paleoenvironmental implications in a semi‐arid, saline playa lake system. SEM image with EDS spectra shows microcrystalline, spherical shaped dolomite crystals from Laguna Fuente de Piedra composed of nanocrystals with bacterial voids and EPS.

Microbial mediation and climatic control on dolomite precipitation in a hypersaline lake: Insights from Salinas Lake, southern Iberia

The Depositional Record, Volume 12, Issue 1, February 2026.
The cyclical nature of aridity and humidity led to the alternating deposition of dolomite‐rich and calcite‐rich sediments. During arid phases, the lake hydrology and growth of microbial mats under evaporative and hypersaline environment favors the precipitation of dolomite.

Precipitation mechanism of anhydrite cement in lacustrine tight sandstone: Implications for fluid activity, mass transfer and pore origin of open diagenetic system in tight sandstone

The Depositional Record, Volume 12, Issue 1, February 2026.
This paper discusses a new model concerning the precipitation mechanismand significance of anhydrite cement in tight sandstone. Anhydrite cement ismainly formed by the dissolution and reprecipitation of early‐diageneticcalcite cements, feldspars and volcanic rock fragments at the mesodiageneticstage.
