A rare part slice of the Martian meteorite NWA 8694, classified as a chassignite, weighing 0.204 g. This specimen preserves both a cut surface and natural fusion crust, offering a complete and highly informative view of this extremely rare Martian lithology.
This specimen is a part slice of the Martian meteorite NWA 8694, weighing 0.204 g and classified as a chassignite, one of the rarest types of Martian meteorites. Despite its small size, it offers a remarkably complete representation of this unusual Martian lithology.
The piece preserves both a cut surface and a portion of its natural fusion crust, making it especially valuable from both a scientific and collector perspective.
Chassignites are among the least common Martian meteorites known. Unlike the more familiar shergottites, they are olivine-rich rocks, believed to originate from deeper levels within the Martian crust or mantle.
This classification places NWA 8694 in a highly exclusive group of meteorites that provide insight into the internal structure of Mars rather than its volcanic surface.
One of the most appealing aspects of this specimen is its format as a part slice with crust. This allows the collector to observe both:
This combination makes the specimen particularly informative, as it bridges the external and internal characteristics of the meteorite in a single piece.
Chassignites are dominated by olivine, a mineral associated with deeper planetary environments. This mineralogical signature distinguishes them clearly from basaltic Martian meteorites and provides valuable information about the differentiation of Mars.
Even in a small specimen such as this, the scientific importance remains significant, as each fragment contributes to the understanding of Martian geology.
At 0.204 g, this is a micro-specimen, yet it carries a strong identity due to its classification and structure. In the field of rare Martian meteorites, such small but complete pieces are often the most accessible way to acquire material from highly uncommon groups.
The presence of fusion crust further enhances its appeal, as it preserves the meteorite’s outer surface as it entered Earth’s atmosphere.
This specimen will appeal particularly to collectors seeking:
It represents a rare opportunity to acquire a fragment of one of the most uncommon Martian lithologies available.
While many Martian meteorites reflect volcanic surface processes, NWA 8694 provides access to a different part of the planet. This small specimen, despite its size, carries that distinction and offers a direct connection to the deeper geological structure of Mars.
