Mantle enrichment of Wudalianchi volcanic rock belt
五大连池火山岩带的地幔富集作用

The Xiaogulihe-Keluo-Wudalianchi-Erkeshan Cenozoic volcanic rock belt is rich in potassium.Neogene leueite basanite from Dangzishan in Keluo,as well as the saxonite mantle enclosures and leucoaegineite magmatic enclosures contained in it.is particularly studied in this work.Abundant evidences of mantle metasomotism are discovered through faciecological and geochemical researches.It is inferred that the enriched mantle comes from ancient lithosphere mantle represented by saxonite,which has experienced fluid ...
