Although previous studies described inclusions of tridymite or cristobalite, the glass inclusions found in the present samples are distributed in planar arrays transecting mineral grains, indicating a secondary origin. These glass inclusions often contain precipitated daughter minerals, such as negative crystals of chromite and troilite. Assuming each of these inclusions originally was a single phase having a homogeneous composition, EPMA and LAM-ICP-MS data suggest that the parent melts were highly silicic and sulphur-rich, and had low abundances of incompatible elements. These glass inclusions in cumulate eucrites and diogenites may be derived from silica-rich melts generated from the incongruent melting of orthopyroxene.}, pages = {200--208}, title = {Highly-silicic glass inclusions in eucrites and diogenites}, volume = {17}, year = {2004} }
