Karst bauxites mark episodic exhumation of carbonate platforms, thus providing key information for basin analysis and paleoclimate processes at the regional to continental scale. Most karst bauxite deposits of SE France lie between Jurassic platform carbonates in the footwall and Upper Cretaceous marine to continental sediments in the hanging wall. These deposits delineate a stratigraphic gap coeval with the Durance extensional tectonics, which led to the separation of the Vocontian and South Provence Basins, and shaped the junction between the Alpine Tethys and the Pyrenean Rift.

法国东南部白垩纪中期铝土矿：地球化学、U-Pb 锆石测年及其对阿尔卑斯特提斯和比利牛斯裂谷交界处古地理学的影响


喀斯特铝土矿标志着碳酸盐平台的偶发性挖掘，从而为区域到大陆尺度的盆地分析和古气候过程提供关键信息。法国东南部的大多数喀斯特铝土矿床位于下盘的侏罗纪平台碳酸盐岩和上白垩纪海洋到上盘的大陆沉积物之间。这些矿床划定了与 Durance 伸展构造同时代的地层间隙，这导致了 Vocontian 盆地和南普罗旺斯盆地的分离，并塑造了阿尔卑斯特提斯和比利牛斯裂谷之间的交界处。
