Geochemistry of Huyanshan Alkaline Complex, Shanxi Province, China: Evidences for the Sources of Magma

摘要

The Huyanshan alkaline complex outcrops in the middle part of the eastern wing of the Lvliang Mountain in Shanxi Province. Due to its typical alkaline rock type, the Huyanshan alkaline complex has attracted much attention from the geological field all the time. This paper describes the characteristic of trace elements of the Huyanshan alkaline complex and discussed the scientific problems such as magma sources and substance composition. The primitive mantle-normalized trace element spider diagram shows that the Huyanshan alkaline complex are enriched in Pb, Hf, Sr, Ba, Cs, Th, U and depleted in Cr, Ni and Co. The data presented indicates that the complex has deep source characteristic and derives from enriched mantle controlled by spinel peridotite partial melting process.
