| 摘 要： | 八里张石膏矿位于合肥盆地北缘,赋存于古近系定远组含盐岩系。古近系定远组是安徽重要的陆相含盐建造。文中结合矿区地质背景,着重从沉积相特征的角度,通过对定远组含盐岩系的岩相特征、沉积规律、形成条件以及河湖相沉积特征规律的分析,对矿区的矿床成因也做了初步分析。认为矿区含盐岩系由河湖相沉积组成,属陆相盐湖沉积,同时在盐湖的形成过程中,盐盆受断裂控制。

| Abstract: | The Balizhang gypsum ore is located in the north of the Hefei basin and deposit occurred on the sale-bearing series of the Dingyuan Formation of the eogene system,the Dingyuan Formation of the eogene system is the important formation of the terrestrial facies salt-bearing in Anhui.This article bases on the mining area geology background,emphatically from sedimentary facies characteristic angle,by doing some researches to the lithofacies characteristic,deposition rule,forms the condition and the fluviolacustrine facies deposition characteristic rule,it shows that the sale-bearing series is composed by the fluviolacustrine facies deposition and belongs to the land facies saline lake deposition in the mining,and that,in the saline lake forming process,the salt-bearing basin is controled by the rifts.From this,the article has also made the preliminary analysis to the ore deposit origin of the mining area. |
