Analysis of Dark Inclusions from Allende
Abstract
Fruland et al. described dark inclusions found in the meteorite Allende as "black to light gray lithic inclusions (xenoliths) that have been found to be different from the bulk meteorite, both petrographically and chemically." Similar dark inclusions have been described from other CV3 meteorites (e.g., Leoville and Vigarano). Most authors have concluded that these clasts are petrogenetically related to the meteorites in which they occur, even though textures can be strikingly different. These inclusions apparently represent materials that have been affected by different processes from those that affected typical CV3 meteorites, or by the same processes either in a different sequence or to different degrees. This abstract reports and interprets new geochemical and mineralogical data for several of these clasts.
