INSTRUMENTAL AND RADIOCHEMICAL NEUTRON ACTIVATION ANALYSIS OF LAYERED CHONDRULES FROM ALLENDE METEORITE

Samples of layered chondrules from allende meteorite are analysed by instrumental and radiochemical neutron activation analysis for Al,Au,Ca, Ce, Co,Cr,Dy,Eu, Fe; Gd, Ho, Ir, La, Lu, Mg, Mn, Na,Nd, Ni, Sc, Sm, Tb, Ti, V and Yb. The distribution and relative position of these elements in the rims and core of layered chondrule can provide some evidence for studying chondrule formation.
