Long-time evolution of sequestered CO$_2$ in porous media [PDF]
, 2014 CO$_2$ sequestration in subsurface reservoirs is important for limiting atmospheric CO$_2$ concentrations. However, a complete physical picture able to predict the structure developing within the porous medium is lacking.

Journal of Phycology, EarlyView.Abstract Microcoleus is a cosmopolitan, filamentous cyanobacterium and a key component of biological soil crusts—complex microbial communities essential for primary production in diverse terrestrial environments. Here, we performed a taxonomic revision of several species of Microcoleus based on a large population genomic dataset.

Rome’s urban history inferred from Pb-contaminated waters trapped in its ancient harbor basins [PDF]
, 2017 Heavy metals from urban runoff preserved in sedimentary deposits record long-term economic and industrial development via the expansion and contraction of a city’s infrastructure. Lead concentrations and isotopic compositions measured in the sediments of

Hydrological reserve "Travertine springs"
Proceedings of the State Natural History Museum, 2023 Travertine springs (petrifying springs) are unique natural formations formed by a complex interaction of abiotic and biotic factors, which cause the precipitation of calcium carbonates and magnesium from solutions saturated with corresponding hydrocarbonates.

Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs
Sedimentology, EarlyView.ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.

A multi-scale approach to determine the REV in complex carbonate rocks [PDF]
, 2013 Complex porous carbonates display heterogeneity at different scales, influencing their reservoir properties (e.g. porosity) especially since different porosity types may exist on different spatial scales.

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers
Sedimentology, EarlyView.ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.
