At about 18:57 hr (Beijing time) on December 1st, 1977, some stony meteorites fell in Xiao Wang Commune, Xin Yang County, Henan Province. The two collected (No. 1 and No. 2) are located respectively at 114°19′22″E, ψ + 32°19′38″N; and λ 114°18′12″ E, ψ + 32°21’31″N, weighing 48kg (No. 1) and 27.5kg (No. 2). Their surfaces are covered with a brownish black regmalypt and characterized by well-developed rhyolitic texture, and absence of pneumatogenic depression. Their mineral composition consists mainly of olivine, bronzite, with accessory minerals such as kamacite, troilite, plagioclase, chromite etc. These meteorites clearly are of chondmlitie structure. From the preliminary study on the mineral composition it is suggested that the Xin Yang meteorite may belong to the ordinary H-group chondrite or named as olivine-bronzite chondrite (H6).
