摘要
山里陈超单元由山里张单元、十八踏单元、山里许单元组成， 相互间呈脉动型侵入接触， 自老至新各单元在岩石学、岩石化学、地球化学等方面均显示出一定联系， 符合同源岩浆演化规律， 从老到新由中性岩向酸性岩演化， 岩石属于高钾钙碱性岩石系列， 岩石成因为Ⅰ型。
The Shanlichen superunit consists of the Shanlizhang unit,Shibata unit and Shanlichen unit, among which pulsation intrusive contact exists The units from old to new are related to one another in petrology,petrochemistry,geochemistry,etc coinciding with the comagmatic evolution law,i e rocks evolving from intermediate to acid from old to new belonging to high-potassium calc-alkali series and I-type genesis.
