Micro-X-ray fluorescence and X-ray absorption fine structure (µ-XRF-XAFS) is one of the most powerful tools to identify the distribution and speciation of trace elements in natural samples with µm spatial resolution. However, conventional µ-XRF-XA

Redox-sensitive metallic elements, Mn and Fe, are oxidized in deep sea waters and form abundant ferromanganese crusts and nodules on the world’s ocean floors at ultraslow rates of growth. This process of oxidation and the mechanism of precipitation

Clays are one of the most abundant minerals on the Earth’s surface, and they play a significant role in global trace element cycling because of their ability to adsorb and incorporate a range of metal cations. However, to what extent clay surface r

Relative contribution of microbially mediated and purely abiotic processes during Mn(II) oxidation is evaluated by investigating microbially colonized manganese deposits at the Sambe hot spring in Japan. Microscopic observations and DNA analyses sugg

Marine ferromanganese crusts and nodules as potential mineral deposits have received increasing attention. However, much less knowledge is available concerning the incorporation and enrichment mechanisms for antimony (Sb) and arsenic (As) in marine f

Adsorption reactions on iron oxyhydroxides (e.g., ferrihydrite, goethite) have considerable impacts on the geochemical cycles of trace elements in natural environments. However, there is a growing recognition that the current state of knowledge that
