| 英文摘要 | The Xiagulihe-Keluo-Wudalianchi-Erkeshan Cenozoic volcanic rock belt is rich in potassium. Neogene leucite 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 metasomotism with the fluids rich in incompatible elements coming from the asthenosphere. While the leucoaegineite enclosures and potassium-rich volcanic rocks comes from partially melting magmas in various stages of such a replacement mantle, and the. volcanic rocks, therefore, has the lower Nd, lower Pb and high Sr isotopic feature. K(2)O/Na(2)O contours are compiled for the whole concerned area, which reveal that the mantle source potassium-rich volcanic rock belt ranges 400 km long and 50 km wide and is controlled by Cenozoic NNW strike intracontinental rift. |
