AI-assisted summary
Description from the seller
Exceptional slice of Howardite NWA 17840, a specimen weighing more than 20 grams and coming directly from the regolith surface of the asteroid 4 Vesta.
This specimen is not just a space rock, but a true geological archive: a polymict breccia (containing fragments of different origins) that holds billions of years of cosmic collisions.
Looking at the panorama of the Howardite slice, the polished surface immediately reveals the complex nature of the rock, very fascinating because it brings together fragments of Eucrites (surface basalts) and Diogenites (deep magmatic rocks).
In macro photographs, one can appreciate the individual crystals and the lithic clasts where plagioclase appears as light, well-defined grains. Analyzing the surface reflections also reveals small accessory minerals such as troilite and metallic iron, distinctive signs of the mineralogical richness of this specimen.
This piece, coming from the prestigious collection of Matthew Stream (whose original label is visible in the photo), is delivered protected in a membrane box. Every detail visible in these images is an open window onto the orderly chaos of our Solar System.
