Abstract

We investigate the use of loess as a proxy for the concentration and isotopic composition of highly siderophile elements, specifically Os, in the upper continental crust. The 187 Os/ 188 Os, platinum group element, and Re concentrations of 16 loess samples from China, Europe, and South America, prev...
