Journal of Sedimentary Research (2019) 89 (2): 147-167.
... aridity, strong winds, high salinity, and low pH makes these among the most extreme surface environments on Earth. This paper provides a comprehensive documentation of the sedimentary processes and products of these rare acid salars for the first time. In addition, this study compares and contrasts salars...

.... These thecamoebians, living in such an extreme environment characterized by the development of “modern” stromatolites, may represent the modern equivalent of lakes present at lower latitudes during past glacial intervals. Further investigation of these protozoans is recommended for their use as paleoenvironmental...

... contributed from groundwater results in some unusual processes, such as direct precipitation of hematite from lake water, and a rare assemblage of depositional and early diagenetic products. This knowledge of natural acid saline lakes expands our understanding of the range of terrestrial extreme environments...

..., and toxic metals. Consequently, brine-related chemosynthetic communities appear to exist in the most extreme environment for life on the seafloor of the Gulf of Mexico slope. The characteristics of hydrocarbon-charged brine expulsion features are likely to be preserved during deep burial, allowing dating...

... environments ( Cho and Tiedje 2000 ; Bell et al. 2005 ). While we focus here on extreme environments, there may be many other types of environmental islands in which examinations of microbial population dynamics are possible. Focusing on extreme island populations enables identification of fundamental...

.... This mechanism illustrates a new pathway of carbon transformation in the subsurface and demonstrates how life can be maintained in extreme environments characterized by long-term isolation and minimal energetic resources. All fractions were analyzed by gas chromatography mass spectrometry (GC-MS) on an HP 6890...
