摘　　要：安徽省定远石膏、岩盐矿床位于肥北凹陷中定远-炉桥凹陷,一系列"垒瓦"式构造盆地和地堑式盆地形成一些低洼,封闭良好的凹陷为矿产的形成提供了良好场所。成矿溶液不断的流入和汇集在最凹陷地区,通过补给、蒸发再补给再蒸发自析成矿,后期复盖迅速。Gypsum and rock salt deposit in the Dingyuan basin, Anhui Province lies in the Dingyuan-Luqiao sag of the Feibei depression. A series of imbricate structural basins and graben-like basins form some low-lying and well-enclosed sags, providing good sites for formation of ore deposits. Ore-forming solution continuously flows in and assembles in the lowest part, evaporates and feeds repeatedly, giving off a deposit, and later covering is prompt.
