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.
