A study that appeared in the 2013 Fall meeting of the American Geophysical Union in San Francisco, Calif., by a team led by Jim Shirley, a research scientist at NASA's Jet Propulsion Laboratory, presented evidence for the existence of a narrow ring of phyllosilicates on the moon's surface, which were uncovered through an analysis of photographs taken with Galileo's Near - Infrared Mapping Spectrometer.

The best match for the spectra proved to be something De Sanctis and her team hadn't even been looking for — clay - like minerals called ammoniated phyllosilicates. (scientificamerican.com)
Ammonia, accreted either as organic matter or as ice, may have reacted with phyllosilicates on Ceres during differentiation. (americaspace.com)
