Introduction: The organic matter in carbonaceous chondritic meteorites has the potential of adding to our understanding of the formation of the solar system. The challenge is that the organic matter constitutes, generally, a small percentage of the total mass of a given chondritic meteorite. Additionally, the physical nature of this carbon provides(More)
Although high concentrations of beryllium-10 and boron are taken as unequivocal indicators of the contribution of subducting plates, controversy persists about the processes by which material is transferred from slabs to the sources of arc magmas. Data on (10)Be/Be and B/Be ratios from four arcs suggest that the contribution from the slab is compositionally(More)
