HUTCHISON R. (2004) Meteorites: A Petrologic, Chemical, and
Isotopic Synthesis (Cambridge Planetary Science Series, pp. 506, p. 92):

Dark inclusions or matrix lumps are present in the members of a number
of groups of the carbonaceous chondrites. The inclusions are mm-sized,
may be chondrule- and CAI-free and generally are phyllosilicate-rich with
magnetite and sulfide and are more aqueously altered than matrix. These
characteristics most closely resemble CI chondrites.
