Sedimentology and geochemistry of saline lake environments in the Atacama Desert, Northern Chile
We characterized the interplay between environmental conditions, microbial, and aquatic life in the Puquios of the Salar de Llamara. In this study, we've learned that salinity plays an important role in setting the style and type of mineral deposition in subaqueous environments:

In this study, we integrated knowledge of physical, chemical, and biological processes occurring in the Puquios to propose a conceptual model linking salinity, lake morphology, lake substrate type and mineralogy. www.sciencedirect.com/science/article/abs/pii/S0048969722024718?via%3Dihub

Geobiology and Geochemistry of Microbial Sediments in the Atacama Desert
Through in situ bottom type mapping and laboratory-based examination of microbial sediments using SEM-EDS from the Puquios, we observed changes in the abundance and structural characteristics of microbially produced extracellular polymeric substances (EPS), which determine mat cohesion, chemical exchange with the environment, and mineral precipitation:

Using focused ion beam scanning electron microscopy (FIB-SEM), we documented an important link between siliceous diatoms and microbial communities, through the formation of Mg-Si protoclays which lead to the eventual precipitation of carbonate minerals in a new mineralization pathway:

Deep Sea Brine Pools, Gulf of Aqaba
Deep sea brine pools are famous for their extremophile microbial communities and unique geochemical conditions that may be analogous to those on early Earth. On a recent OceanX expedition, a new system of brine pools was discovered and named the NEOM Brine Pool complex:
