《矿物学报》１９９５年第４期发表了何宏平的“天然烧变高岭石中水铝英石发现”一文。该文用核磁共振谱中－７９．０×１０－６附近的谱峰，认为该信号来自水铝英石，而不是来自Ａｌ－Ｓｉ尖晶石。这种说法较合理，因刘长龄早就阐明偏岭石在成岩阶段由水铝英石变来。但是我们不同意“天然煤烧变高岭石经后期水化作用变成水铝英石”的观点，而主张“水铝英石是沼泽相原生沉积的；在成岩作用中转变为偏岭石不是煤烧的，有一些理化性质与变高岭石的不同” “Mineral Journal” in 1995 the fourth issue of He Hongping “natural albino kaolin fever found” article. In this paper, the spectral peak near -79.0 × 10-6 in the nuclear magnetic resonance spectrum is considered to be derived from allophane rather than Al-Si spinel. This argument is more reasonable, because Liu Changling has long been elucidated that during the diagenetic stage, the albite was changed from allophane. However, we do not agree with the view that “natural coal-fired kaolinite changes into diaspore later in hydration.” It is argued that “allophane is originally deposited as a swamp phase; it is transformed into a pyrophyllite during diagenesis Not burning coal, there are some different physical and chemical properties and kaolinite ”
