中文摘要: |
贵州省务正道铝土矿床是黔北—渝南铝土矿成矿带上的重要矿床,属于典型的沉积型铝土矿床。通过对铝土矿矿石的电子探针、扫描电镜、X-射线衍射等分析,发现组成铝土矿的主要矿物为一水硬铝石。铝土岩常具有撕裂状构造,反映出铝土岩系属滑塌沉积,没有经过长距离搬运,表明区内含矿岩系沉积环境属陆相的河湖盆沉积。成矿母岩主要是中下志留统韩家店页岩、泥岩。 |
英文摘要: |
The Wuchuan-Zheng'an-Daozhen bauxite deposit southern Chongqing-northern Guizhou bauxite belt in northern Guizhou Province are ascribed to the bauxite deposit. Electron probe microanalysis,X-ray power diffraction patterns,and SEM-EDS show that diaspore is the main mineral of the bauxite. Bauxite rock is often ripped up reflecting sedimentary slumping without long distance transportation. The sedimentary environment is terrestrial river-lake basin. Mother rock is mainly shale and mudstone of the Lower-middle Silurian Series. |
