Abstract— Microchondrules with apparent diameters of 2 to 150 μm are found in a black carbon—bearing inclusion in Mezö‐Madaras. Some are homogeneous (glassy or micro‐crystalline) others show two phases: mainly silica and a pyroxene‐rich glass. The bulk chemical composition of the inclusion is related to the host‐chondrite in which silica‐pyroxene chondrules are ubiquitous. Small black lumps of the same kind are dispersed in bulk Mezö‐Madaras. This L‐related carbon‐bearing material may represent a new specimen of C‐rich ordinary chondrite.
