Abstract: The paper "The Existence of Allophane Heated Metakaolinite" was published by He Hongping et alin No4 of Acat Mineralogica Sinica, 1995.In the paper, the author thought that the spectrum peak ar-round -79.0 × 10- 6of M ASNMR spectra was originated from allophane, not from Al-Si spinel.This opin-ion is relatively rational because Liu Changling had stated that pianlinite originated from allophane dur-ing diagenetic stage.Howeuer, we don't agree with the opinion that heated kaolinite became allophanethrough late hydration, we think allophane is originally deposited in swamp;during diagenesis it changesinto planlinite, thus pianlinite is not formed by coal combustion, Some of its physical and chemical prop-erties are different from that of metakaolinite.
