.83" Fusion Crusted Eucrite Meteorite (3.89 g) - NWA 11504

NWA 15658 is an HED polymict eucrite originating from the dwarf planet Vesta in the asteroid belt. This is a more recent find: the main mass being a 5.8 kilogram stone was purchased from a Moroccan dealer in 2022. When sliced it reveals large and variable basaltic clasts surrounded by a dark shock-melt matrix that displays flow textures in places.

Eucrite Meteorites - Fragments Of 4 Vesta

Eucrites are achondritic stony meteorites thought to have originated from the surface of the giant asteroid (or minor planet) 4 Vesta. Vesta is the second largest body in the asteroid belt, measuring 326 miles wide. Like Earth, it has the differentiated layers of crust, mantle, and core common to rocky planets: this may mean that 4 Vesta is the remnant of a larger destroyed planet.

Eucrites consist of basaltic rock from Vesta's crust ejected during a collision with another asteroid. Eucrites are mostly composed of calcium-poor pyroxene, pigeonite, and calcium-rich plagioclase (anorthite). Vesta is currently one of just seven identified solar system bodies of which we have physical samples.
