Metal in various forms is common in almost all meteorites but considerably rare among micrometeorites. We report here the discovery of two metal micrometeorites : 1. An awaruite grain similar to those found in the metal nodules of CV chondrites. 2. Metal micrometeorite of kamacite composition...
Iridium is found in meteorites. Isotopes Two naturally occurring isotopes of iridium exist, iridium-191 and iridium-193. Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is ...
Sadly, here in the real world, we just have steel. There are no hidden mines spitting up extra special sword metal, no meteorites raining magic space iron down on our heads. Myth 3: Katanas Are the Greatest Sword Ever Invented If you’ve ever watched a Tarantino then you are well ...
In: Metal Detector The Spectra V3i is the flagship metal detector for the White’s brand. It’s the ultimate land-based metal detector for everything from prospecting to finding meteorites and lost jewelry. It has a Salt Beach mode, and while VLF single frequency detectors struggle here, th...
In a study published in 2013 in the Journal of Archeological Science, researchers examined ancient Egyptian iron beads that date to around 3200. They found that they were made from iron meteorites.It’s A Ferrous Metal…There are non-ferrous (non-magnetic) and ferrous (magnetic) metals. For ...

A dull bracelet and a rusted hollow hemisphere decorated with gold are forged, researchers have found, not out of metal from beneath the ground, but with iron from meteorites that fell from the sky. 研究人员发现,一个黯淡无光的手镯和一个锈迹斑斑的饰有金饰的空心半球不是用地下的金属锻造的,而是...
The compound naturally occurs in meteorites but has attracted renewed attention as a potential material for permanent magnets, and elemental additives will likely be necessary to facilitate the phase formation. Our density functional theory calculations use the Viennaab-initiosimulation package, applied to...
