| 摘 要： | 剑阁球粒陨石于1964年10月9日(或19日),陨落于四川省剑阁县杨家村公社民主大队。1964年12月,经四川省地质局实验室涂继尧等同志初步定为石陨石。1966年3月,我所钟大赉和刘秉光两同志,由四川省地质局实验室得到一小块大小为6.2×5×1.8公分,重222克的标本(照片1)。陨石的原形和大小现已无法查清。恩施球粒陨石于1974年12月26日15时30分陨落于湖北省恩施县芭蕉区,地理坐标东经109°51′20″,北纬30°34′40″。1977年9月,笔者赴现场调查时,据直接了解情况的李建华同志介绍,当时在瓦屋公社、乾溪公社和寨湾公社交界处的上空,突然由西北往东南方向发出声响,在70-80里的范围内都能听见。尔后掉下多块陨石。

| Abstract: | On October 9 (or 19), 1964 a chondrite fell in Jiange County, Sichuan Province, and on December 26, 1974 another fell in Enshi County, Hubei Province (109°1′20″B, 30°4′40″N).According to the microscopic examinations both chondrites studied are composed of the following minerals: orthopyroxene (in the Jiange one Fs=16, in Enshi one Fs=15), olivine (in the former Fa = 18; in the latter Fa = 17), iron-nickel, as well as troilite; plagioclase, chromite and ilmenite being of less importance.Based on their mineralogical and chemical characteristics the Jiange chondrite may be ascribed to the type of H5-6 and the Enshi chondrite to the type of H5. |
