摘要 新西兰科罗曼德地区安山岩经热液作用形成了含有80%以上叶蜡石带和高岭石-地开石-石英和高岭石-水铝石带的粘土矿床。该沉积物是在超过 2,000 psi 的压力下在地球深处形成的。且温度高于 335°C。矿床中叶蜡石的分子式为[Al(OH)2)]+0.1 Al2 [Si3.90Al0.10] O9.05(OH)2.10，X射线衍射图和差示热分析图与文献中给出的类似，但不相同。通过 X 射线衍射技术鉴定了矿床中的地开石和纤铁矿；通过 X 射线衍射和光学技术分析水硬铝石。
Abstract Hydrothermal action has formed a clay deposit with a zone containing over 80% pyrophyllite and other zones containing kaolinite-dickite-quartz and kaolinite-diaspore from andesite in the Coromandel area New Zealand. The deposit was formed deep in the earth at pressures over 2,000 p.s.i. and temperatures above 335°C. The pyrophyllite in the deposits has the formula [Al(OH)2)]+0.1 Al2 [Si3.90Al0.10] O9.05(OH)2.10, and an X-ray diffraction pattern and differential thermogram similar to, but not identical with, those given in the literature. Dickite and lepidocrocite were identified in the deposits by X-ray diffraction techniques; diaspore by X-ray diffraction and optical techniques.
