| Meteorite - Watson 001, IIE iron. |
| In 1990, during the analysis of Watson 001, a
prominent silicate inclusion was found to have a composition matching the H
chondrites (minus the metal kamacite-troilite content). The oxygen isotope composition of this stony mass also matched the IIE iron meteorite class inferring the same parent body. A current model for this iron proposes that the silicate inclusion in Watson 001 was an H chondrite mass engulfed in a subsurface Fe/Ni melt within its parent body. There are 17 known meteorites in the IIE class of irons. Ongoing research has shown a link between them and the H chondrite parent body. This association between IIE irons and the H chondrite parent body is being refined. A scholarly document search will produce multiple papers on the subject. There is, however, less published research about the volume of dendritic melt pockets seen in Watson 001. The focus of this segment is to provide imaging stimulus and support for further study of this structural phenomenon. The dendritic texture and lamellae distortion argue for secondary structures. |
