Trace element identification of very low titanium (VLT) and low titanium (LT) basalts from Mare Fecunditatis and Mare Crisium regions: SR-XFA and INAA studies of lunar samples

Abstract

The very low titanium (VLT), low titanium (LT), and titanium (T) basalts of the Eastern part of the Moon were investigated by SR-XFA and INAA methods. New intermediate VLT-LT basalt groups were distinguished on the basis of titanium contents, REE patterns and trace element distributions. All basalt groups were compared and conclusions about possible sources of these basalts and their origin were drawn.
