摘要
黔中一带早石炭世准溶原面上,发育大量岩溶负地形,诸如溶盆、溶洼等。负地形中沉积了由粘土岩、铝土岩、铝土矿、铁质岩及赤铁矿等组成的九架炉组。九架炉组是由陆相冲洪积作用及湖泊作用形成的,据研究,其沉积类型有岩溶湖泊、洪控岩溶湖泊、扇三角洲、冲洪积扇(包括洪泛洼地)及洪控溶洼五种,它们的沉积特征如图2所示。
In Early Carboniferous karst peneplain of Central Guizhou there were a lot of karst negative forms, for example karst basin, karst depression. Under the control of alluvial-proluvial deposition, Jiujialu Formation consisting of claystone (mudstone) ,bauxitic rock, bauxite, ferruginous rock formed in it. According to the research result of metallogenic provance of bauxite in central Guizhou, the sedimantation type of Jiujialu Formation can be classified into five kinds as Fig. 2 in Chinese edition (P. 6). They are karst lake type, flood karst lake type, fan delta type, alluvial-proluvial fan type, flood karst depression type.
