On the basis of the study on the petrology, Trace element, and isotopic geochemistry, the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting. One is the basanite-alkaline basalt-Olivine tholeiite magma series, which are generated by partial melting from spinel Iherzolite; the other is nephelinite magma-alkaline picritic basalt magma, which are generated by partial melting of the garnet Iherzolite.

岩石化学、微量元素、同位素地球化学证据都表明，华北、华南地区的火山岩根据源岩和局部熔融程度的不同，可以分为两个原生岩浆系列：一个是源岩为尖晶石二辉橄榄岩，随着局部熔融程度的增加，形成的碧玄岩岩浆-碱性玄武岩岩浆-橄榄拉斑玄武岩岩浆；另一个是源岩为石榴石二辉橄榄岩，随着局部熔融程度的增加形成的霞石岩岩浆-碱性苦橄玄武岩系列。

From the Late Carboniferous to the Permian, Junggar region into the post-collision tectonic evolution stage, in the stage of the post-collision, the early subduction slab rupture and separate, asthenosphere decompression melting, basalt magma take place underplating, because the underplating of the basalt magma, low crust melt by the high temperature forming the acid crust-magma, the basic magma from mantle and acid one from crust mixing at the vicinity of the crust-mantle boundary, formed the Huangyangshan magma mixing plution, the dioritic microgranular enclaves are the recorder of the crust and mantal magma mixing process.

从晚石炭世到二叠纪，准噶尔地区进入后碰撞构造演化阶段，在后碰撞构造阶段，早期的俯冲板片断离，软流圈减压熔融，玄武质岩浆底侵至下地壳底部，底侵基性岩浆带来的巨大热量，导致地壳物质熔融，形成大规模的花岗质岩浆，两种岩浆在壳-幔边界附近发生不同程度的混合，其中闪长质微细粒包体就是基性的幔源岩浆和酸性的壳源岩浆不同程度的混合的记录者。

There are three genetic types of mineral deposits in the Beiya ore district:① Cu-Au polymetallic deposits related to alkaline porphyries, comprising porphyritic Cu-Au deposits and polymetallic skarn deposits related to quartz-albite porphyry and quartz-K-feldspar porphyry;② Fe-Au deposits related to gabbro or basalt magma, consisting of magmatic Fe-Au deposits and sedimentary polymetallic deposits formed in caves and lakes; and ③ palaeo-placers formed at the weathering surface, in lakes and in karsts.

北衙金矿有3种成因不同的矿床：①与碱性斑岩有关的铜金多金属矿，包括与石英钠长斑岩和石英正长斑岩有关的斑岩型铜金矿床和矽卡岩型多金属矿床；②与辉长－玄武岩浆有关的铁金矿床，包括熔浆型铁金矿床和喷流沉积型多金属矿床，后者又有洞穴和湖相沉积环境之分；及③古砂矿，有古风化壳型砂矿、河湖相古砂矿和洞穴沉积古砂矿。

Under the action of the active faults stretched deeply to magma chambers,the mantle gas released directly from the magma chambers by taking the faults as the paths is characterized by the CO2／3He ratios of 107～109 which are lower than the ones of the original mantle gas just separated from basalt magma.

我国五大莲池、云南腾冲、吉林长白等火山活动区温泉释放的幔源气体CO2／3He比率受到幔源气体释放机制的控制，在深切岩浆房的断裂活动作用下，以断裂为通道直接自岩浆房中释放的幔源气体，以低于幔源气体脱离岩浆时的CO2／3He比率为特征，其比率为 107～109。
