Anoxic and iron-rich (ferruginous) conditions prevailed in the ocean under the low-oxygen
atmosphere that occurred through most of the Archean Eon. While euxinic conditions (ie …

Photoferrotrophy, the process by which inorganic carbon is fixed into organic matter using
light as an energy source and reduced iron [Fe (II)] as an electron donor, has been proposed …

Abstract Rogoznica Lake, on the Adriatic coast of Croatia, undergoes vertical mixing in
autumn, but quickly restratifies and becomes intensely sulfidic during the succeeding 11 …

Fe isotopes can provide new insight into redox-dependent biogeochemical processes.
Precambrian iron formations (IF) are deserving targets for Fe isotope studies because they …

The availabilities of iron and phosphorus have considerably impacted biological productivity
in past and present natural aquatic environments, and therefore have been key regulators of …

Iron isotopes have been extensively used to trace the history of microbial metabolisms and
the redox evolution of the oceans. Archean sedimentary rocks display greater variability in …

Marine dissolved organic carbon (DOC), the largest pool of reduced carbon in the oceans,
plays an important role in the global carbon cycle and contributes to the regulation of …

This study explores the long-term drivers of changes in lake mixing regime and the causes
of lacustrine anoxia in the 2000 year-long, varved sediment record from Lake Żabińskie in …

Despite the historical and economic significance of banded iron formations (BIFs), we have
yet to resolve the formation mechanisms. On modern Earth, neutrophilic microaerophilic Fe …

Abstract Rogoznica Lake (RL;“Zmajevo oko”) is a shallow marine body of water that exhibits
the physical characteristics of lakes (layer overturn and morphology), estuaries (distinct …
