Scientific and Physical Characteristics

NWA 16901 displays a recrystallized chondritic texture consisting of partially preserved chondrules and lithic fragments embedded within a fine recrystallized matrix. The chondrules show an average apparent diameter of approximately 737 µm (n=67). Secondary plagioclase occurs as fine-grained recrystallization products with a grain size of around 35.6 µm (n=26). Accessory mineral phases include high-calcium pyroxene, plagioclase, troilite, chromite, and apatite.
