A thin section of green pyroxene Mantle-peridotite xenolith from San Carlos Indian Reservation, Gila Co., Arizona, USA. The xenolith is dominated by green peridot olivine, together with black orthopyroxene and spinel crystals, and rare grass-green diopside grains. The fine-grained gray rock in this image is the host basalt.(unknown scale).

The pyroxene pallasite grouplet is a subdivision of the pallasite meteorites (stony-irons). [1] The grouplet is named "pyroxene pallasites" because they are the only pallasites that contain pyroxene. The grouplet was proposed in 1995. [2] It currently has only two members: the Vermillion and Yamato 8451 meteorite.
The triangle, viewed face-on, appears equilateral. In (4), the distances of P from lines BC , AC and AB are denoted by a ′ , b ′ and c ′ , respectively. For any line l = s + t n̂ in vector form ( n̂ is a unit vector) and a point p , the perpendicular distance from p to l is
