| 摘 要： | 豫西石炭系铝土矿形成于华北古夷平面上,沉积于华北陆表海-湖泊环境中。豫西石炭系铝土矿围绕隆起区分布及太原组海陆交互相的沉积特征,使人认为铝土矿形成于古陆边缘。本文通过对豫西铝土矿的区域地质背景、含矿岩系特征及其形成的古地理环境以及典型矿区地质构造的综合分析认为,豫西石炭纪"古陆"并不存在,豫西的现代地貌和石炭纪有天壤之别,新生代以来的构造运动是豫西铝土矿出露定位的控制性因素,豫西铝土矿围绕隆起区分布的特征是后期、尤其是新生代以来的构造运动造成的。

| Abstract: | The Carboniferous bauxite deposits in the western Henan Province occur on the planation paleosurface and was deposited in epicontinental seas or lakes of the North China Block. Based on their distribution around the upwarping areas and occurrence in the Taiyuan Fm., these deposits have ever been considered to form in paleo continental margins. However, combined data from regional geology survey, paleogeographic reconstruction of the ore-bearing rocks and geological characteristics of typical ore deposits indicate that the previously hypothesized Carboniferous paleocontinent did not exist in the area. The current physiognomy of the western Henan Province is quite different from that in Carboniferous, and is extensively modified by Cenozoic tectonic movements. The distribution of the bauxite deposits around the highlands in the western Henan Province is controlled by the later tectonic movements, especially those taking place in the Cenozoic. |
