DISCOVERY OF AN UNMELTED H-CHONDRITE INCLUSION IN AN IRON METEORITE

The link between H chondrites and silicate inclusions in group IIE iro n meteorites has long been suspected, but direct evidence for a common parentage has remained elusive. The discovery of an unmelted chondrit ic inclusion in the Techado iron meteorite sheds light on the genetic relation between these two groups, providing clues on the origin of ch ondritic materials as inclusions in iron meteorites. It is proposed th at the complex IIE iron meteorite breccias formed by collisions with s everal different bodies, followed by deep burial of metal and silicate fragments in the asteroidal megaregolith.
