Robust element abundance analysis is introduced here to diminish non-robustness involved in traditional solutions, so that the results are not susceptible to the presence of outliers in observations, which is a general phenomenon in geochemical datum sets; otherwise, the calculat results may deviate from the real ones.This paper describes briefly some basic concepts of robust statistics, including breakpoint and influence function. And then a contamination model is constructed for geochemical data, i.e.,...
