摘要
The potassium-magnesium salt deposit in Khammouan Province of Laos is located in the eastern Khorat Basin which belongs to Upper Cretaceous salt sedimentary basin. This paper mainly studied the mineralogical and geochemical characteristics of the lower salt layer based on ZK318 well. The results show that halite, sylvite and carnallite are main minerals, with small amounts of boracite and anhydrite. In combination with the characteristics of minerals, major elements and trace elements, the lower salt layer can be divided into five layers in upward order of halite layer→ sylvite layer→ carnallite layer→ thin halite layer→ upper sylvite layer.oft-com:office:office" />
