岩浆

From on minerogenetic epoch, major take formed permocarboniferous period, very few has early palaeozoic; On the minerogenetic tectonic enviroment, major located on the rigidity basement of lie concealed, formed Igneous Instrusion and Volcanism of orogenic cycle.

从成矿时代看，多数矿床形成于石炭－二叠纪，少数形成于早古生代，成矿构造环境多数位于有隐伏刚性基底之上，形成于造山旋回构造岩浆活化带。

Based on petrographic, major and

事实上，HT和LT2玄武岩也是该大火成岩省边缘部分的主要岩浆类型。

Therefore, degassing of the undegassed mantle is the main source of CO2 in petroliferous basins.

因此，未脱气的幔源岩浆脱气作用成为含油气盆地CO2的最主要来源。

Petrologic method was employed to estimate the T and P condition of the generation: 1630-1680℃ and 4GPa, and the temperature is much higher than asthenospheric mantle.

利用岩石学方法估算出岩浆形成时的温度达1630－1680℃，压力为4GPa，远高出软流圈地幔温度，从而为地幔柱的存在提供了确切的依据。

Subduction of a hot active ridge will significantly affect the thermal state of the subduction zone, and leave tectonic and petrologic signatures.

热的活动海岭俯冲会对岛弧周围岩浆活动、变质作用及地形变化产生影响。

All or part of phanerocrysts seems disequilibrium with the glass or ground mass in which they are contained now,however, traditional realization is that the phanerocryst are grow up from the magmas.

传统上认为是从母岩浆中生长出来的斑晶晶体，现在看来全部或者部分并没有和包含它的玻璃质或者基质达到平衡。

The mechanism is similar to that of an intrusive magma, with the salt deforming and behaving plastically under pressure.

其机制类似於入侵型岩浆，它因为盐类的存在而变形、并在一定的压力下而有塑化的表现。

Combining the available regional geological and geophysical research, the petrogenesis of the magmatism was studied. As a response and absorption to the IndiaAsia collision, the northeastward flow of the asthenosphere beneath the Tibetan Plateau along the 400 km depth interface was blocked by the North China craton, and caused a systemic sequences in West Qinling Region, including the strikeslip fault systems and pullapart basins in the shallow crust and the origin of the twotype magmatism in this work in deep lithosphere. This explanation is consistent with the lithology and plumelike geochemical features of the kamafugite and potassic trachybasalt, which are significantly different from the potassic magmatism within the plateau and its adjacent regions.

结合前人对该区深部地球物理和断裂构造的研究，论证了火山岩的起源与成因，指出作为对印度-欧亚大陆强烈碰撞的吸收与调节，高原下软流圈地幔流沿400 km界面向北东方向的侧向流动以及西秦岭周边克拉通块体的阻挡，是形成西秦岭断裂系左行走滑特征和巨大拉分盆地的主要原因，也是导致西秦岭新生代两类钾质火山岩和碳酸岩起源与成因的动力学机制，较好地解释了西秦岭新生代岩浆作用起源深度大，具有地幔柱源的地球化学特征，岩石组合与地球化学有别于高原内部及其周边地区新生代钾质火山岩的原因。

It is considered that the quartz vein has something to do with concealed igneous rock., and its forming is because of pneumatolytic hydrothermal upwelling from magma differentiation in the deep.

综合分析认为，该区石英脉与推测隐伏火成岩体紧密相关，深部岩浆分异后期的气成热液上涌是石英脉形成的主导因素。

Therefore, these gold deposits are typically polygenetic compound ore deposits.

正是地洼阶段这种构造—岩浆作用才形成了有经济意义的金矿床，这些矿床是多因复成矿床。
