X-ray mapping is increasingly used in the geological sciences for qualitative observations of textures, mineral zoning, and element distribution among rock components [1] [2] [3] [4] . We combine mapping with an aggressive program of image analysis in deepening our understanding of the early solar system through the analysis of chondritic meteorites [5, 6] . Chondrites are "sediments" that accreted in the earliest solar system into planetesimals now represented by objects in the asteroid belt.

... hey accumulated hightemperature inclusions (igneous rock droplets or aggregations) with a low-temperature fine-grained mineral matrix including pre-solar grains and macromolecular carbon [7] . We seek to measure the relative abundances, modal mineralogies, and chemical compositions of these components with such different thermal histories, to higher accuracy than has been done previously. 752
