深部陆壳的生长及壳幔相互作用是地质学家们关注的一个问题。火成岩及其中的深源包体是研究壳幔深部作用的一个重要途径。文中以济南辉长岩及其深源包体的研究为例，揭示华北陆台地区造山带陆壳增厚的特征。济南辉长岩具造山带火成岩属性。辉长岩中首次发现的尖晶石单辉岩和石榴石单辉岩包体与中国东部新生代玄武岩中的辉石岩包体不同，其主要矿物为深绿辉石，以及钙铝榴石、钙长石、方解石等一些富钙矿物和镁铁尖晶石等。这些辉石岩包体并非来源于上地幔，对岩石组构、矿物组成以及矿物化学研究表明，辉石岩包体也不是从寄主辉长岩中直接结晶出来的。根据相平衡关系、矿物化学特征研究以及热力学计算表明，这种特殊类型的单辉岩包体来自大约５０～６０ｋｍ的深部陆壳，可能是下地壳富钙物质与岩浆底侵作用的产物。这些记录表明本区燕山期是一个增厚的陆壳。
The growth of the deep continental crust and the interaction of the crust and mantle are a problem that geologists are concerned about. Igneous rocks and their deep-sourced inclusions are an important way to study the deep crust-mantle action. Taking the study of gabbro and its deep-sourced inclusions in Jinan as an example, this paper reveals the characteristics of the continental crust thickening in the Orogenic Belt in the Lutai region of North China. Jinan gabbro with orogenic igneous property. The spinel monopyroxene and garnet monochromic inclusions, first discovered in gabbro, are different from the pyroxenite inclusions in Cenozoic basalts in eastern China. The main minerals are pyroxene, as well as goethite, , Calcite and some other calcium-rich minerals and magnesium iron spinel. These pyroxenite inclusions are not derived from the upper mantle. Studies on the rock structure, mineral composition and mineral chemistry show that the pyroxenite inclusions are not crystallized directly from the host gabbro. According to the phase equilibrium relationship, the study of mineral chemistry and the thermodynamic calculation, it shows that this special type of monopyrite enclaves come from the deep continental crust of about 50 ~ 60km, which may be the product of the calcium rich material and magma underplating in the lower crust. These records indicate that the Yanshanian period in this area is a thickened continental crust.
