The dynamics and transformations of micronutrients (Zn, Cu, Fe, Mn, B and Mo) in soils, are
governed by various factors like pH, EC, soil organic matter etc. Soil organic matter (SOM) is …

Molybdenum is an essential trace element for human, animal and plant health and has
played an important part in the evolution of life on earth. Nonetheless, exposure to the …

Paleoredox conditions are commonly evaluated based on elemental proxies but, despite
their frequency of use, most of these proxies have received little comparative evaluation or …

Although marine productivity is a key parameter in the global carbon cycle, reliable
estimation of productivity in ancient marine systems has proven difficult. In this study, we …

The redox-sensitive transition element molybdenum is present in the Earth's crust at trace
concentrations but is abundant in seawater, marine sediments, and ancient sedimentary …

The oxygen content of the Earth's surface environment is thought to have increased in two
broad steps: the Great Oxygenation Event (GOE) around the Archean–Proterozoic boundary …

Shales and mudrocks are enriched with diverse suites of major elements and trace metals
that reflect their depositional environment, provenance and diagenesis. Here we present …

To improve estimates of the extent of ocean oxygenation during the late Ediacaran Period,
we measured the U and Mo isotope compositions of euxinic (anoxic and sulfidic) organic …

Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

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 …
