岩浆

On the basis of the study of the P-T diagram of magmatic evolution, plutonic structure, study on magmatic dynamics and geophysical data, it is showed comprehensively that, Jiuzihe granite pluton is an in situ-parautochthonous pluton that emplaced along NE shear zones.

岩浆演化的P-T图、岩体构造和岩浆动力学研究以及地球物理资料综合表明，九资河花岗岩体是一沿NE向剪切带就位的典型原地—半原地花岗岩岩体，与世界其它典型原地—半原地花岗岩相比，该类花岗岩为造山带所特有。

They have A/CNK values of 0.9～1.2, suggesting aluminum saturation or ersaturation, and are enriched in LREE and LILEs and depleted in HFSEs. Their δEu values are 0.11～0.32, evidently indicating plagioclase fractional crystallization.(87Sr/86Sr)i ratios and εNdvalues are 0.707?9～0.716?1 and -6.90～-7.70 for volcanic rocks, and 0.7086～0.7098 and -7.10～-7.68 for quartz syenitic porphyrite, respectively, implying that all the igneous rocks from the Yandang Mountain were evolutional products of co-magmas, and derived mainly from the crust, mixed however with mantle components.

岩石富集轻稀土元素和大离子亲石元素，相对亏损高场强元素；δEu值为0.11～0.32，表明岩浆经历了以斜长石为主的强烈结晶分异作用；火山岩(87Sr/86Sr)i为0.707 9～0.716 1，εNd为-6.90～-7.70，中央侵入体石英正长斑岩(87Sr/86Sr)i为0.708 6～0.709 8，εNd为-7.10～-7.68，表明它们是同源岩浆不同阶段分异演化的产物，物质来源主要为陆壳，但也有地幔物质参与。

The PGE distributive patterns are the PtPd type, the Pt/Pd ratios of 0.32-0.68 are between the values of enriched sulfide tholeiite (0.38) and primitive upper mantle (1.36), and the similarity of partition patterns of chondritenormalized REE, MORB-normalized trace element and primitive mantle normalized PGE for the rocks of the three phase zones, indicate the Baimazhai intrusive body I formed by the evolution, liquation, intrusion and diagenesismetallogenesis of basaltic magma.

铂族元素配分模式为Pt-Pd型，w/w比值为0.32~0.68，介于富硫化物拉斑玄武岩(0.38)和原始上地幔(1.36)之间，以及稀土元素配分模式、微量元素蛛网图和铂族元素配分模式中不同岩石配分曲线的相似性揭示3个相带不同岩石之间的高度一致性，展示基性-超基性岩形成于玄武质岩浆演化、熔离及岩浆一次性侵入、分异成岩成矿的特征。

But, the crust rocks (included to accumulating complex, sheeted sill complex and lava) is formed by crystallization of the magma. The different rock associations of pyroxenite gabbro and troctolite gabbro in the accumulating complex are related to depth of formation of magmatic chambers and oxidation state of magma in the spreading ridge.

而壳层岩石(指堆积杂岩、岩墙杂岩、熔岩)则是由岩浆结晶作用形成的；堆积杂岩中出现辉石岩辉长岩和橄长岩辉长岩的不同岩石组合则与堆积岩岩浆房出露的深度和氧化状态有关。

Measurements of S, O, and radiogenic isotope ratios are all potentially powerful tracers of magma interaction with country rocks and the importance of assimilation processes in the genesis of magmatic Ni-Cu-PGE deposits.

硫、氧同位素和放射性同位素比值在示踪岩浆与围岩的反应及在岩浆镍－铜－铂族元素矿床成因中同化过程的重要性方面有很大作用。

对于岩浆熔体物理性质和结构以及二者关系的研究是岩石学研究的前沿课题，也是岩浆热力学研究的中心。

Based on the subcrustal mantle convection-generated stress field inversed by gravity anomalies, together with its relationship to the Cenozoic volcanism in the plateau, and the mechanism of crustal fracture formation, as well as the numerical results of the evolution of mantle convection beneath the plateau, this paper investigates the deep mechanical mechanism for the formation of a magma transportation channel in the Tibetan Plateau.

为了研究火山形成基本要素―岩浆运移通道的形成，基于重力异常反演的青藏高原下地壳底部的地幔对流应力场，结合地壳破裂形成机理和对流应力场与青藏高原新生代火山分布的关系，以及青藏高原下地幔对流演化的数值模拟结果，分析了高原火山岩浆运移通道产生的深部力学机制。

But detail geochemical study indicates (Wu et al., 2002)that those rocks have low Sr〓(0.706), high ε〓(-0.5～-1.9), young age of Nd model age (970-1090Ma) and syngenesis with surrounding I-type granites. The rock originated from partial melting of source igneous rock and belongs to I type granites. The occurrence of high alumina minerals is related to the intense interaction of magma and liquid during the late period of magma evolution, and tetrad REE patterns are formed.

但详细的地球化学研究表明(Wu et al。，2002)，岩体具有低的Sr〓(0.706)、高ε〓(-0.5～-1.9)、年轻的Nd模式年龄(970-1090Ma)及与周围Ⅰ型花岗岩的共生关系，认为岩体是火成岩源岩物质部分熔融的产物，属于Ⅰ型花岗岩，高铝矿物的出现与岩浆演化晚期强烈的岩浆—流体相互作用有关，并形成特征的稀土元素四分组效应。

Its primary magma is high MgO tholeiite.

原生岩浆是高镁拉斑玄武岩浆。

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
