Abstract: A kind of crystal of mixed-layer dickite-kaolinite has been found in sedimentary rock at Lingshan, Quyang County, Hebei Province. The length of its grain is 2mm and its diameter is 0.5mm long. The characteristics of this mineral are as follows: its differential thermogram with midtemperature; endothermic polypeaks at 550℃ and 656℃ and a small peak at 685℃; infrared spectrogram with 3705, 3695,3670, 3655, 3620 and 3598cm-1 absorptions of high frequency range; X-ray diffraction curve with continuing four classes of strong peaks,and its I(004)/I(006)=2.88.
