NWA 15200 is a rare Martian Nakhlite purchased in 2022 after recovery from Algeria. Nakhlites are an uncommon group of Martian meteorites formed through igneous activity on Mars before being ejected from the planet by a powerful impact event. As a Nakhlite, NWA 15200 provides direct material from Martian volcanic processes, offering insight into a specific and scientifically important group of rocks from the Red Planet.

Specimens of NWA 15200 typically show a dark fusion crust on the exterior, while broken surfaces can reveal a mixture of green, orange-brown, and cream-coloured grains. Its mineralogy is described as augite-rich, with additional phases including ferrohypersthene, fayalitic olivine, andesine plagioclase, aluminium and potassium-rich mesostasis, titanochromite magnetite, ilmenite, and troilite. This mineral assemblage gives NWA 15200 a distinctive crystalline character linked to Martian volcanic history.

Studying NWA 15200 provides valuable insight into Martian magmatism, cooling history, and the alteration of volcanic rocks on Mars. Its rarity, official classification, and distinctive mineralogy make it especially desirable for collectors focused on planetary meteorites and Martian material. Each specimen represents genuine rock from Mars, preserving part of the planet’s volcanic evolution and its journey from the Martian surface to Earth.
