Iron spherules
WebIron-nickel spherules, as much as 0.5 mm in diameter, have been found completely embedded in some philippinites. The spherules consist mainly of kamacite with unidentified pink inclusions. The meteoritic origin of these spherules seems reasonable, suggesting that the tektites containing them were formed by asteroidal or meteoritic impact. ... WebThe shape of the Ni-Fe spherules found in the Isabela tektite, Pi-73, prevents them from exhibiting ordinary ferromagnetic properties except in magnetic fields in excess of 6000 oe. For this reason, the Owen-Honda equation ordinarily used at low fields to detect the presence of ferromagnetic impurity cannot be used to detect the presence of these …
