Abstract
In September 2024, a grey rock, weighing 670 grams, arrived at our laboratory, on which numerous dark clasts and metallic particles could be seen, within a fine-grained, dispersed, fragile and easily disintegrable matrix. The analyses concluded that it was a polymictic eucrite, and its official classification was presented, which ends on December 9, 2024 with the name NWA 17204.
