| 摘 要： | 文章在对含矿岩系岩石组合、地球化学分析的基础上,认为矿区铝土矿形成于华北地块从早古生代准平原状态向晚古生代陆表浅海过渡时期,早期海侵之后的陆地湖泊环境中.被碳酸盐岩覆盖、较小地形差异的陆地准平原状态,湿热的气候,繁茂的植物使得岩溶湖泊成为铝土矿富集和保存的有利场所.

| Abstract: | Based on studies of ore - bearing rocks and geochemistry, it is suggested that bauxite deposits in western Jiyuan were sediments in lake - environments after transgression when North China Block turned from peneplain in early Paleozoic to epeiric sea in late Paleozoic. Land covered by limestone, peneplain, humid climate, and flourish plants made karst lakes the best places for enriching and preservation of bauxite. The area covered by Permian strata in the northeast parts is good for prospecting. |
