The authors think that the magmas of the intermediate-acid volcanic rocks were derived from basaltic magmas of the lower crust and are mixed magmas produced by the increase of geothermal gradients due to diapiric injection of basaltic magmas and partial melting of intermediate-basic metamorphic igneous rocks in the lower crust,and that they resulted from a series of tectonomagmatic activities that took place when the closing of the Mongolian-Okhotsk sea trough and continent-continent collision caused crustal thickening and brought about the formation of the Hinggan-Mongolian orogenic belt in the process of oblique subduction of the Paleo-Pacific plate beneath the Siberian plate.

中文摘要：通过对大兴安岭北段晚侏罗世吉祥峰组中酸性火山岩的岩石地球化学研究，发现其中存在高Sr低Y型火山岩，即文献上所称的埃达克质岩，笔者认为中酸性火山岩的岩浆起源于下地壳玄武质岩浆，为玄武质岩浆底辟上侵引起地热梯度增加、下地壳中基性变质火成岩石部分熔融的之混合岩浆，是古太平洋板块向西伯利亚板块斜向俯冲过程中，蒙古鄂霍次克海槽封闭，陆壳碰撞使地壳加厚，形成兴蒙造山带时所引起的一系列构造岩浆活动。

Study suggests the strata of this block are of the following feature: various sequence interface types, first-class fault and tectonic movement control strata framework styles; formation and evolution of Maodun sub-high makes single-lined fault dustpan-type depression complicated to produce unsymmetrical grabens and igneous rock, which influences detrital rock infilling pattern in the depression.

The igneous diversity is not only induced by the magmatic processes but also by the processes caused production of magmas.

火成岩的多样性不仅仅取决于岩浆作用过程，而且也取决于岩浆形成过程。

Spinel is a compound of magnesia and alumina(Al2O3) and is thus a magnesium aluminate(MgAl2O4), found as accessories in igneous rocks, in metamorphosed aluminous schists, in contact metamorphosed limestones and sometimes in high temperature iore veins.

尖晶石主要成分是氧化镁和氧化铝，结晶习性是等轴晶系漂亮的正八面体。镁被铁置换就是铁尖晶石，被锌置换就是锌尖晶石，铁完全置换镁形成磁铁矿，铬置换铁尖晶石形成铬铁矿，这些类质同相的等轴晶系都是八面体结晶的尖晶石族矿物。
