| 中文摘要:在贵州省西南部安龙县戈塘乡一带的黄钾铁矾化交代石英岩中,发现了极其罕见的天然矿物——自然铝。 本自然铝主要分布在黄钾铁矾的端点、边缘或充填在空洞中,少数分布在石英颗粒间。自然铝常与自然铜、自然硫等密切伴生,并交代黄钾铁矾。 本文详细介绍了自然铝的物理性质、化学成分及矿物共生组合等。 |

| DISCOVERY OF NATIVE ALUMINIUM IN THE OXIDATION ZONE IN GETANG, ANLONG COUNTY, GUIZHOU PROVINCE |

| Abstract:Native aluminium (Al), rarely found in nature, was discovered in the jarositized quartzitic rock of replacement origin in Getang Anlong County, Guizhou Province, China. The bulk of the native aluminium occurs in cracks in and along boundaries of jarosite, and only a small amount is present in and along the grain boundaries of quartz. It is frequently associated with native copper and sulfur which have replaced jarosite.Electron-probe analysis shows that it contains 97.811% of aluminium, and electron diffraction and X-ray powder method indicate that a0 is 4.0507A. So it is considered as native aluminium. |
