从岩石学、岩石化学、微量元素、ＲＥＥ等方面讨论了嵩山古元古代钾长花岗岩体的地质地球化学特征，结果表明这些岩体属于Ａ型花岗岩，其ＳｉＯ２、Ｋ２Ｏ、Ｋ２Ｏ／Ｎａ２Ｏ、Ｆ、Ｇａ、Ｈｆ、Ｒｂ、Ｙ、Ｃｏ、Ｇａ／Ａｌ、ＲＥＥ高，Ａｌ２Ｏ３、ＭｇＯ、ＣａＯ、Ｎａ２Ｏ、Ｂａ、Ｓｒ、Ｖ、Ｔｈ低，Ｅｕ为０．１５～０．２７，Ａ／ＣＮＫＭ＜１．１０，这些岩体是与古元古代熊耳群火山岩相伴生的钾质侵入岩，两者均形成于非造山的大陆裂谷环境，表明华北陆台南缘在古元古代晚期处于拉张的非造山构造环境。
The geochemical characteristics of the Paleoproterozoic potash-bearing granite in Songshan were discussed from the aspects of petrology, petrochemistry, trace elements and REE. The results show that these rocks belong to A-type granites with SiO2, K2O, K2O / Na2O, F, Al2O3, MgO, CaO, Na2O, Ba, Sr, V and Th are low, Eu is 0.15-0.27, and A / CNKM <1. These rock masses are potassic intrusive rocks associated with the volcanic rocks of the Xionger Group in the Paleoproterozoic, both of which were formed in the non-orogenic continental rift environment, indicating that the southern margin of the Lugai of North China was in a non-orogenic phase in the late Paleoproterozoic Construction environment.
