构成山西南部塔儿山超单元的三个岩浆岩单元（塔儿山二长闪长岩单元，老山石英二长岩单元，交界山霓辉正长岩单元），是燕山期熔融程度较低的幔源岩浆，在深部岩浆房中分异演化，脉动侵位而成。本区金属成矿与矿质在岩浆演化不同阶段富集有关，同时受不同演化阶段岩浆中主要元素含量制约，由此形成成矿作用的时空结构：早期二长闪长岩—铁成矿，中期石英二长岩—铜成矿，晚期霓辉正长岩—金成矿
The three magmatic rocks (Tarshan monzodiorite unit, Laoshan quartz monzhang unit and Jiaozhan flunite syenite unit), which constitute the Tashan unit superhighway in southern Shanxi, are of relatively low degree of melting in the Yanshan period Mantle magma, differentiated in the deep magma chamber, pulsation emplacement. Metallogenic mineralization in this area is related to mineral enrichment in different stages of magmatic evolution and controlled by the major elements in magmatic rocks in different evolution stages, thus forming the space-time structure of mineralization: early diorite-iron mineralization, Quartz monzonite - copper mineralization, late Nepheline syenite - gold mineralization
