贵州铝土矿资源丰富,是中国第二大铝土矿资源基地,约占全国铝土矿资源总量的17%(张军伟,2012)。主要分布在修文-清镇、凯里-黄平、遵义-瓮安和正安-道真等4个矿集区(董家龙,2004),贵州铝土矿具有如下一些规律性的特点:(1)含矿地层的层位:修文-清镇矿集区与遵义-瓮安矿集区的含矿地层为下石炭统九架炉组,而正安-道真矿集区的含矿地层为上石炭统大
Guizhou bauxite is rich in resources and is the second largest bauxite resource base in China, accounting for about 17% of the total bauxite resources in the country (Zhang Junwei, 2012). Mainly distributed in the Xiuwen - Qingzhen, Carey - Huangping, Zunyi - Weng’an and Zheng’an - Daozhen 4 mining areas (Dong Jia Long, 2004), Guizhou bauxite has the following regular features: (1) Stratigraphic strata: the Xiuwen-Qingzhen ore-gathering area and the Zunyi-Weng’an ore-bearing area are nine Lower Carboniferous formations, whereas the ore-bearing strata in the Zheng’an-Daozhen ore area are Upper Carboniferous
