Scientific paper

Seven samples of the St. Mesmin meteorite, which is unique in being the only ordinary chondrite known to contain an unmelted xenolith of another ordinary chondrite, have been analyzed by both instrumental and radiochemical neutron activation for Na, Ca, Sc, Cr, Mn, Fe, Co, Ni, Zn, Ga, Ge, Se, In, Sm, Yb, Ir, and Au. It is found that, as in other regolithic chondrites, the dark host has higher contents of highly volatile elements than do the light clasts; it is suggested that this is the result of a combination of differences in intensity of preexisting metamorphism, as well as a redistribution of volatiles during regolith gardening. It is also determined that while the H-group xenolith in St. Mesmin is a relatively recent addition to the parent body, this fact does not require regolith activity at that time.
