| 中文摘要: |
| 渝南—黔北铝土矿成矿带是西南地区一个重要的铝土矿成矿带,矿床工业类型为产于泥岩(碳酸盐)侵蚀面上的一水硬铝石铝土矿矿床。成矿带内铝土矿中的矿物主要为一水硬铝石,其次为高岭石、勃姆石、三水铝石、伊利石、绿泥石、叶蜡石、蒙脱石等、以及褐铁矿、纤铁矿、赤铁矿、黄铁矿、石英、白云石、方解石、锐钛矿、锆石、金红石、电气石等。各种矿物晶体细小,一般小于5μm。一水硬铝石为主要的有用矿物,其晶体形态以短柱状为主,其次为粒状、鳞片状。一水硬铝石含量高,而且矿石质量好者,其沉积环境为水动力条件较差的远岸较深水的相对宁静环境；反之,一水硬铝石含量低,且矿石质量差,其沉积环境为水动力条件较好的近岸浅水风浪环境。 |
| 英文摘要: |
| The Metallogenic belt of South Chongqing - North Guizhou is an important Metallogenic belt in southwest of China. The industrial type of ore deposits is:Produced in mudstone (carbonate) surface erosion of a diaspore bauxite mineral bauxite in this metallogenic belt is deposits. the mainly a diaspore, followed by kaolinite、 Boehmite、Gibbsite、Illite, chlorite, pyrophyllite、montmorillonite、Limonite、 lepidocrocite、 hematite、 pyrite、 quartz、 dolomite、 calcite、 anatase、zircon、 rutile. the mineral crystals is very small, generally less than 5 μm. A diaspore useful as the main mineral. The crystal form a short column, followed by granular, scaly. The high content of a diaspore, the ore good quality; Conversely, poor quality ore. A high content of diaspore, the sedimentary environment was far less dynamic conditions of water shore to deeper water is relatively quiet environment; a low content of diaspore, the sedimentary environment with better conditions for the hydrodynamic waves in shallow water near shore environment. |
