Writeup from MB 92:

Weikengquan                    40°16´N, 99°49´E

Jiuquan City, Gansu Province, China

Find: 2 November 2006

Ordinary chondrite (H5, breccia)

History: The stone lay on sand close to dunes at the northwestern boundary of the Badanjilin desert. H. Zang recovered the stone on the way from the base to Weikengquan.

Physical characteristics: The stone is 665 g, roughly ball-shaped and ~10 cm in diameter. It has a complete fusion crust with many cracks penetrating inside. Sand grains adhere on the crust.

Petrography: (Y. Lin, B. Miao and S. Hu, IGGCAS) It is a brecciated chondrite, consisting of numerous almond-like clasts cemented by fine-grained impact melt. In the clasts, chondrules are readily recognized, and there are much more abundant troilite than metallic Fe-Ni. In the melt breccias, metallic Fe-Ni and troilite occur as small spheres, and there are nodule-like clasts with ringwoodite rims and wadsleyite interior.

Mineral compositions: Olivine (Fa19.4±0.4) and low Ca-pyroxene (Fs17.1±0.2) are homogeneous, but plagioclase shows variation (An11.7-20.6Ab69.8-85.5Or1.5-10.6).

Magnetic susceptibility: log χ (in 10-9 m3/kg) 4.45.

Classification: Ordinary chondrite (H5, breccia); S6, W3.

Type specimens: A sample of 359 g is on deposit at IGGCAS. The finder holds 306 g.
