Chemical compositions of the ALH-77302 polymict eucrite
The abundances of 16 major, minor, and trace elements (Fe, Na, Cr, Co, Sr, Ba, Sc, La, Nd, Sm, Eu, Tb, Yb, Lu, Hf and Ta) in two matrices, one fusion crust, 10 igneous clast samples of ALH-77302 polymict eucrite have been determined by instrumental neutron activation analysis. The abundances of 14 m...
