Abstract Magnetite is the most common magnetic phase in carbonaceous chondrites. Comprehensive and detailed investigations of this magnetite with X-ray diffraction and electron microprobe have revealed minute amounts of substitutional impurities (e.g. Ni) in the magnetite, but no other magnetic oxides have been found in these meteorites. Using an external magnetic field and Mössbauer spectroscopy, we have found a component in the Mössbauer spectrum that we attribute to maghemite. The relative area of this component implies that maghemite accounts for approximately 12% of the magnetic oxides in Orgueil.
