序盐丘,是盐类物质在一定地质条件下运动的产物。其形态甚为奇特,结构也很复杂。根据盐类物质与上覆地层的关系,分为两种类型:1)岩株(栓)没有刺穿上覆地层的,称为盐背斜(图1);2)刺穿上覆地层的,谓之底辟构造(图2)。盐丘的这种特殊构造形态,提醒研究蒸发岩成盐条件的人们:在有盐岩沉积的盆地内,是否有盐类物质的运动和盐丘的 Salt salt mound, is the salt material under certain geological conditions, the product of the movement. Its shape is very strange, the structure is also very complicated. According to the relationship between the salt material and the overlying strata, there are two types: 1) the rock strain (bolt) does not pierce the overburden and is called a salt anticline (Figure 1); 2) , That the diapir structure (Figure 2). This special configuration of salt domes reminds people of the salt formation conditions of evaporites: whether there is salt movement and salt domes in basins with salt rock deposits
