Oxidation of selenium (Se) largely drives the mobilization of soluble selenium oxyanions from rock and soil. Isotopic fractionation of selenium (82Se/76Se) has been used to track attenuating proces...

Adsorption plays an important role in the biogeochemical cycling of selenium (Se) in natural environments and Se isotope fractionation during adsorption is a significant but poorly studied part of Se isotope system. This paper examined Se(IV) and Se(

Isotope dilution (ID) method has been widely applied to studies of elemental speciation and certification of the concentrations of geological reference materials. One of the key factors restricting the application of the ID method is the difficulty i

Selenium (Se) stable isotopes are a new geochemical tool with great potential as a tracer of redox processes and chemical cycling of chalcophiles and volatile elements. However, Se isotope measurements in low-Se samples present a formidable analytica

The cross sections of the selenium isotopes 76Se, 77Se, 78Se and 80Se within 10.5–19.81 MeV neutron energy range have been measured through neutron activation method along with off-line γ-ray spectrometry. The quasi-monoenergetic neutrons were pro

Isotope systematics of the redox sensitive and chalcophile element selenium (Se) were investigated on exhumed parts of subducted oceanic lithosphere to provide new constraints on slab dehydration conditions during subduction. The samples c,, show inc
