Winonite Meteorite (NWA 13790)

Winonites are a rare and extraordinary class of primitive meteorites, belonging to the enigmatic group of achondrites.

These ancient space travelers are believed to have originated from a partially differentiated parent body—an ancient world where molten metal and silicate materials once separated in a process that echoes the very formation of planets. Winonites are a cosmic treasure trove, revealing a striking blend of silicate minerals like olivine and pyroxene, interspersed with metallic grains of nickel-iron alloys, a rare and fascinating composition that bridges the gap between the primitive and the evolved. 

Their unique structure holds the key to unlocking the mysteries of early solar system processes, especially the enigmatic events of partial melting and planetary differentiation. Named after their first discovery near the rugged landscapes of Winslow, Arizona, winonites offer a glimpse into the primordial chaos that shaped our cosmic neighborhood. These meteorites preserve invaluable clues about the transition between chondritic meteorites—raw, unrefined remnants of the solar nebula—and the fully differentiated planetary bodies that would one day become worlds like our own. Studying winonites is like peering into the heart of a planet's earliest evolution, offering insights that transcend time and space.
