盐矿易溶于水,很容易被地表水流所破坏,只有在隔水层保护下,才能被保存下来。因此,大部分盐矿上部有较新地层复盖,埋藏深度比较大,一般无明显的找矿标志,只有在气候干旱的条件下,且风化剥蚀强烈的地区(如青海、新疆、西藏等)才能直接出露地表。 Salt mines are easily soluble in water and easily destroyed by surface water flow, which can be preserved only under the protection of aquitards. Therefore, most of the upper salt strata are covered with newer strata, and the depth of burial is relatively large. There is generally no sign of ore prospecting. Only in areas with arid climate conditions, such as Qinghai, Xinjiang and Tibet, In order to directly expose the surface.
