In about 25,000,000 year, the Changbai Mountain area experienced 4 volcanic eruption activity, the basaltic magma embarked from the upper mantle, upwelled unceasingly along the earth's crust in giant crevasse, spouted the surface by the huge energy (in geology to be called crevasse type volcanic eruption).

在大约2500万年的时间里，长白山地区经历了4次火山喷发活动，玄武岩浆从上地幔出发，沿着地壳中的巨大裂隙不断上涌，以巨大的能量喷出地表（地质学上称为裂隙式火山喷发）。

The change of REE composition between the upper and lower samples from Hongcan well implied the tectonic setting and property of the sediment provenance in Zoige Basin were altered obviously between late-period of Middle Triassic and mid-period or late-period of Late Triassic. This change was probably due to elevation and erosion of the matured continental crust on the east of Zoige Basin, and lots of clastic materials transported into the basin in late-period of Late Triassic.

通过对比杂砂岩稀土元素组成在上层和下层样品之间的变化，若尔盖盆地内中三叠世中期到晚三叠世中期及晚期沉积物源区的构造背景和性质发生了明显的改变，而这一变化很可能是盆地东侧成熟陆壳在晚三叠世后期被抬升和剥蚀，其大量碎屑物质被带到盆地的结果。
