Marine evaporite formed in Upper Jurassic Suowa Formation, Middle Jurassic Xiali and Buqu Formations, Lower Jurassic Quemoco Formation and Upper Triassic Bagong Formation, respectively. Thick salt layers are discovered in middle-lower section of the Xiali Formation, Middle Jurassic in the Shenglihe Depression, Northern Qiangtang Basin. Total thickness of the salt is 351m, and amount of salt layers is 32 with thickness of separate layer of salt range from 2m to 50m. Color of the salt changes from violet red, light red and pink to white and grey, and the salt layers are interbedded with gypsum, marl, mudstone and limestone in the Middle Jurassic Xiali Formation. Major component of the salt is sodium chloride (NaCl), containing Na 17-38%, Cl 20-50%, Mg, 1.0-1.9 and Ca 0.4-5.1%; and some salt layers contain potash with K 0.5-1.7%. Salt as thick as 300-350m, 200-300m, 100-200m and 50-100m cover area of 46km2^, 55 km2^, 117km2 ^and 218km², respectively, in the Qingshuihu foreland basin, central Shenglihe Depression. It is revealed that halite resource of 100 billion-tonne exists in the Shenglihe Depression, which indicates potential for exploration of moraine potash in the Qiangtang basin.
