Scientific paper
Soil fragments in the 106-150 and 150-250 micron size ranges were selected for metallographic and microprobe examination on the basis of their magnetic properties. Serial sections of the mounted fragments were examined. One fragment proved to be a compositionally zoned crystal of phosphide with no metal phase but partly embedded in glass. Another was a coarse-grained association of silica with ilmenite and fayalite with a 5-micron particle of metallic iron in troilite. One splinter of oxide contained a central spine of metallic iron. The remaining six fragments contained 10-micron particles of iron-nickel-cobalt alloy with compositions in either the 'meteoritic' or the low Ni-low Co sub-meteoritic composition ranges of Ni, Co content. In some fragments separate particles of alloy had different Ni, Co contents. No particles of high Co metal were encountered.
