• Geological, pedogenic products:
• Anthropogenic (military hardware):
• Fulgurites:
• Known meteorites (ureilite) & Cosmic spherules:
• Necsa Chemist gone berserk in the lab:
native metal grains (Ti, Al, Pb, Ag, Zr, Zn, Bi) + alloys (SnCa) +
ceramics+ nitrides (TiN1-x) + carbides (CxNx-1 [S, K]*; SiC) +
+ multiwalled carbon nanotubes? + glassy PSi *& Ag-Si-Ti-Al
metal spherules
• Direct relation to the Hypatia stone:
Hypatia stone hosts comparable metals and alloys/metallic
compounds (SiC, large Ti filaments; Al metal, AgPI grains);
carbonaceous (N, S-bearing) filaments.
Hypatia: Carbonaceous filaments, metals

The parent body of the Hypatia stone might have been be a comet but NOT like any of those already sampled/investigated, i.e.:.
Comet Wild 2 …. Stardust Mission Comet 67P/Churyumov–Gerasimenko…. Rosetta Mission Comet Tempe 1 ….. Deep Impact Mission IDPs + GEMS collection…. flights by NASA, other agencies Ultracarbonaceous Antarctic Micrometeorites... Antarctic expeditions Comets 103P/Hartley 2…. EPOXI mission C/2009 P1 (Garradd)…Herschel Space Observatory
