This pile of xenoliths was collected during field work at the Joya de los Contreras maar. The Santo Domingo maars are the source of mantle-derived spinel-lherzolite xenoliths and deep-crustal granulite xenoliths. The light-colored areas on the rims of the xenoliths are a coating of caliche. The scale at the lower right marks 10 cm on the left side.
