The Dumre area, located in Central Albania, is distinguished by a landscape whose main features consist of low altitude, mosaic and irregular relief, and the presence of a large number of depressions with lakes. These features result from karst development related to the presence of a tectonically affected dome of Triassic evaporite rocks, mainly gypsum. Gypsum karstification has operated since the Pliocene, and the present-day geomorphological appearance of the area indicates an advanced, mature stage of karst development. Signs of this maturity include the widespread occurrence of large depressions, many of which are water-filled, forming lakes, the occasional presence of gypsum hills in the form of monadnocks, a thick “coating” of residual sediments largely isolating the karstic gypsum substrate from precipitation and surface waters, and the fragmentary pattern of a degraded river network. The karst character of the relief is largely “camouflaged” by clastic terrigenous and residual deposits of considerable thickness which cover the gypsum and form a caprock. At the present stage, the caprock is being strongly reshaped and eroded. Chemical analyses show a mean dissolved gypsum content of 1.9 g/l and mean dissolved NaCl content of 0.4 g/l. The mean flow rate of subaqueous springs is calculated as 1.84 m³/s. The density of gypsum is 2.3, and that of rock salt is 2.17, thus the total volume of gypsum dissolved each year is 47,420 m³ and of rock salt 10,680 m³, making a total volume of dissolved material released by the subaqueous springs in one year of 58,100 m³. This corresponds to a cubic void of side length 38.7 m.

位于阿尔巴尼亚中部的杜姆雷地区以低海拔、马赛克和不规则地势为主要特征的景观以及大量湖泊洼地的存在而著称。这些特征来自与受构造影响的三叠纪蒸发岩圆顶（主要是石膏）的存在有关的岩溶发育。石膏岩溶作用自上新世以来一直存在，该区现今的地貌形态表明岩溶发育已进入高级、成熟阶段。这种成熟的迹象包括大洼地的广泛出现，其中许多是充满水的形成湖泊，偶尔存在以单丘形式存在的石膏山丘，残留沉积物的厚“涂层”在很大程度上将岩溶石膏基质与降水和地表水，以及退化河网的碎片化格局。地势的岩溶特征在很大程度上被相当厚的碎屑陆源和残余沉积物“伪装”起来，这些沉积物覆盖了石膏并形成了盖层。在现阶段，盖层正在被强烈地重塑和侵蚀。化学分析显示平均溶解石膏含量为 1.9 g/l，平均溶解 NaCl 含量为 0.4 g/l。水下泉水平均流量计算为 1.84 m 9 g/l，平均溶解 NaCl 含量为 0.4 g/l。水下泉水平均流量计算为 1.84 m 9 g/l，平均溶解 NaCl 含量为 0.4 g/l。水下泉水平均流量计算为 1.84 m³ /秒。石膏的密度为2.3，岩盐的密度为2.17，因此每年溶解的石膏总量为47,420 m ³，岩盐的密度为10,680 m ³，使水下泉水释放的溶解物质总量合二为一年 58,100 m ³。这对应于边长为 38.7 m 的立方空隙。
