Our understanding of the complex aqueous chemistry of iron in natural systems has advanced significantly over recent years. Here we will highlight how new contributions from nanogeoscience combine with conventional aqueous geochemistry to provide a novel view of kinetics in the modern iron biogeochemical cycle, and the evolution of the iron cycle through geologic time. We start by considering t...

Peatlands are an important global carbon reservoir. The continued accumulation of carbon in peatlands depends on the persistence of anoxic conditions, in part induced by water saturation, which prevents oxidation of organic matter, and slows down decomposition. Here we investigate how and over what time scales the hydrological regime impacts the geochemistry and the bacterial community structur...

Correlation analyses were conducted on nickel (Ni), vanadium (V) and zinc (Zn) oral bioaccessible fractions (BAFs) and selected geochemistry parameters to identify specific controls exerted over trace element bioaccessibility. BAFs were determined by previous research using the unified BARGE method. Total trace element concentrations and soil geochemical parameters were analysed as part of the ...

salman and resalat oilfields are such marine oilfields that are in vicinity of each other. there is resalat oilfield in distance about 80-90 kilometers from lavan island in persian gulf. this oilfield is located in 25 kilometer southwest in reshat oilfield. salman oilfield is located in vicinity of water border line of united arab emirate in 140 kilometers of south of lavan island. this oilfiel...

The stability of soil organic matter (SOM) plays a critical role in carbon (C) dynamics under global warming. However, the factors influencing SOM stability, particularly significance bedrock geochemistry and its hierarchical relationship with climate properties, remain poorly understood. To address this gap, we conducted study along large climatic gradient (Δtemperature > 9 °C) subtropical ...
