Mineral composition control on intermineral iron isotopic ...

Feb 01, 2017· Intermineral iron isotopic fractionations of magnetite–biotite, plagioclase–magnetite and alkalifeldspar–magnetite are correlated with the compositions of biotite, plagioclase and alkalifeldspar, respectively. This may reflect the compositional effect of mineral composition on the intermineral fractionation of Fe isotopes. (3)

Mineral Dust and Iron Solubility: Effects of Composition ...

There is significant iron deposition in the oceans, approximately 14–16 Tg annually from mineral dust aerosols, but only a small percentage (approx. 3%) of it is soluble and, thus, bioavailable. In this work, we examine the effect of mineralogy, particle size, and surface area on iron solubility in pure mineral phases to simulate atmospheric processing of mineral dust aerosols during transport.
