东向洼地是位于大汶口凹陷西部的构造洼地，有利的构造条件、古气候古地理条件、周边丰富的物源，形成了盆地内的岩盐矿床。区域构造演化，造成洼地内构造沉积幅度、卤水浓度差异，从而岩盐沉积相也有了一定的演化，主要趋势为沉积中心自沉积中心自东向洼地西北部沿走向 SWW 向向洼地中西部转移，沉积厚度也随之变化。
東嚮窪地是位于大汶口凹陷西部的構造窪地，有利的構造條件、古氣候古地理條件、週邊豐富的物源，形成瞭盆地內的巖鹽礦床。區域構造縯化，造成窪地內構造沉積幅度、滷水濃度差異，從而巖鹽沉積相也有瞭一定的縯化，主要趨勢為沉積中心自沉積中心自東嚮窪地西北部沿走嚮 SWW 嚮嚮窪地中西部轉移，沉積厚度也隨之變化。

Dongxiang depression Is a structural depression located in the west of Dawenkou basin.Favoura-ble structural conditions,ancient climate,geographical conditions,and the surrounding rich source formed rock salt deposit in the basin.Regional tectonic evolution caused sedimentary range and the concentration differences of brine.Thus,rock salt sedimentary facies have a certain evolution.The main tendency is a-long the direction of SWW from the northwest to the midwest of Dongxiang depression.The sedimentary thickness changes as well.
