Advantages

Distinguishes mineral origins

Electron microscopy reveals two primary mineralogical populations: nickel-poor iron particles in basalt clasts (magmatic origin) and nickel-rich metallic iron and Fe-Ni alloys in breccias, agglutinates, and glassy materials (impact origin).

Applications

• Lunar Sample Research：Use farside samples to reveal ferromagnetic mineral origins and constrain lunar magnetic evolution.
• Rock Magnetism：Distinguish magmatic from impact origins via magnetic measurements, improving rock magnetic interpretation.
