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.
