Distribution of Ca, Fe, K, and S between soluble and insoluble material in the Greenland Ice Core Project ice core
We have developed an original method coupling particle induced X ray emission and scanning electron microscope/X ray dispersive analysis in order to characterize the partitioning of Fe, Ca, K, and S between the soluble and the insoluble phases in wind-blown deposits in the Greenland ice. We applied...
