摘　　要：The Heimugou loess profile in Luochuan County, Shaanxi Province is 135 m thick, and the stratum being continuous and intact, typical in the loess area. The authors found some extremely fine filar substances when investigating the clay minerals from this profile with transmission electron microscope (hereinafter, TEM). The content is too low to test with other methods. With TEM, the micromorphology, electron diffraction spectrum, X-ray energy spectrum and other characteristics of those extremely small fibres can be observed. According to the observing results, they are initially determined as imogolites.
