摘要 广西自新生代以来,进入了地洼余动期,在温暖潮湿的气候条件下,形成了大面积的三水型铝土矿化。笔者运用遥感技术对它们进行较详的研究,尤其研究铝土矿矿物和伴生矿物的波谱特征,围岩(沉积岩)的波谱特征,与铝土矿化有密切关系的地貌特征、植物特征、土壤盖层特征等,并运用数字图像处理技术来增强那些与铝土矿化有关的信息,减弱或压抑与铝土矿化无关的信息,然后,在经处理后的卫星图像上进行铝土矿解译,圈定找矿靶区。最后,进行了野外实地验证工作,在广西南部前人发现的三水铝矿床的基础上,于武鸣县发现了几处矿化区。 Since the Cenozoic, Guangxi has entered the residual-mobility period of diwa stage. Under the hot and humid climate condition, a large area of bauxite mineralization has occurred. The remote sensing technic was applied to the studies of bausite, especially of the wave-spectrum characteristics of bauxitic minerals and sedimetary rocks in the region, of the geomorphological features of the bauxitic region, and of property of vegetation and soil above the deposit. Digital image Processing technic was then used for stressing on the characteristics resulting from the bauxite mineralization, and for reducing what are caused by mineralization-unrelated factors. The landsat image processed was interpreted and several zones were pointed out as the favorable zones for prospecting. Finally, the field investigation. was carried out and some bauxite minerzlized areas were discovered m Wuming,Guangxi.
