1916年3月23日中午在河北省任邱县议论堡未家村陨落了一块球粒陨石(北纬38°40′,东经116°08′)于1975年才由北京天文馆收集和保存,重约300克,陨石表面为褐黑色的熔壳所包裹,断口面呈褐黑灰色,次生氧化作用非常明显。X射线粉晶衍射分析和显微镜下的薄片观察表明,任邱球粒陨石主要由橄榄石、斜方辉石、斜长石、金属镍-铁(以铁纹石为主)及陨硫铁组成。整个陨石显示细—中粒的全晶质结构,局部呈变斑晶结构,
At noon on March 23, 1916, in Renqiu County, Hebei Province, a chondrite meteorite (38 ° 40’N, 116 ° 08’E) was dropped in the village of Buweijia only collected and preserved by the Beijing Planetarium in 1975 at a weight of about 300 G, the surface of the meteorite is covered with a brown-black fused shell, the surface of the fracture is brownish grayish gray, and the secondary oxidation is very obvious. X-ray powder diffraction analysis and observation under the microscope showed that Qiu chondrite is mainly composed of olivine, orthopyroxene, plagioclase, metallic nickel-iron (mainly composed of ferrite) and pyrite . The whole meteorite shows fine - medium grain all-crystalline structure, the local showed a change of phenocrysts,
