Studies of petrology and petrochemistry indicate that such suit of volcanic rocks dominated by lattite belongs to shoshonite series to potassic alkali basalt series. Considering the stability of rocks and their associations, gentle stratum occurrence, fresh degree of rocks and comparatively clarity of horizons. this potassic volcanic stratum distributed over the Sailipu area is named as Sailipu Formation, and the age of which is early middle Pleistocene of Quaternary.

岩石学、岩石化学研究表明，这套火山岩是以安粗质熔岩为主的钾玄岩系列－钾质碱性玄武岩系列火山岩，岩石类型及岩石组合稳定，岩层产状平缓，岩石新鲜，层位相对清楚，故将其命名为赛利普组，属第四纪早－中更新世。
