晋豫(西)晚石炭世本溪期铝土矿及其共生矿产是中国北方石炭纪含煤地层的重要矿产,本区是其集中产区之一,属华北地台铝土矿粘土矿成矿区。铝土矿石储量约占我国储量的50％,占中国北方储量的70％。因此,研讨这一地区的铝土矿及其共生矿产的沉积分布规律,实践上、理论上都有重要意义。 The Late Carboniferous Benxi Period Bauxite and Its Symbiotic Mineral Deposits in Jinyu (West) Period are important minerals in the Carboniferous coal-bearing strata in northern China. This area is one of the concentrated producing areas and belongs to the bauxite clay mineralization area of ​​the North China Platform . Bauxite reserves account for about 50% of China’s reserves, accounting for 70% of reserves in northern China. Therefore, to study the sedimentary distribution of bauxite and its symbiotic minerals in this area is theoretically significant in theory.
