Chemical studies of H chondrites — 7. Contents of Fe 3+ and labile trace elements in Antarctic samples
Abstract— Linear discriminant analysis and logistic regression have been applied to concentration data for 10 labile trace elements (Rb, Ag, Se, Cs, Te, Zn, Cd, Bi, Tl and In) in 33 Antarctic H4–6 chondrites. The proportion of bulk Fe in the Fe 3+ state, Fe 3+ /Fe, of these same chondrites permit th...
