We have reported the fractionated abundance pattern of alkali metals and REEs in Acapulco and other acapulcoites (Y-74063 and ALH-78230) and suggested that the loss of partial melts had occurred during formation processes of acapulcoites. Such lithophile features have not been well discussed in Zipfel et al. In order to confirm this feature, further analyses (by isotope dilution, atomic absorption and ICP-AES) of alkali metals (Na, K and Rb), alkaline earths (Ca, Mg, Sr and Ba), REEs and other elements (Cr, Mn, Fe, Co, Ni and Zn) were carried out for two more acapulcoites (ALHA81187 and ALHA81261) and Acapulco-Lodran intermediate type (EET84302). Two different portions (interior and exterior samples) of each meteorites have been analyzed in this work.
