2The studies on the appearance typomorphism, physical typomorphism, inner structure typomorphism and chemical typomorphism of the zircon and garnet, and the result of U-Pb isotopic age dating of zircon indicate that the zircons are meta-morphogenic genesis but two or three of them are magmatic genesis and most meta-morphogenic zircons have a basic magmatic zircon core which was generated in Stage of Yanshand and Indo-Chinese epoch. The genesis and origin of the garnet is very complicated. The garnets are main almandine with high Fe and Mg content and were proposed their souce rocks are mostly regional mid-degree-metamorphic rocks.

2研究锆石和石榴石的形貌标型、物性标型、内部结构标型以及成分标型特征和锆石U-Pb同位素测年结果表明，锆石除少数几个为岩浆锆石外，绝大多数是变质锆石，且中间多有形成于燕山-印支期的基性岩岩浆锆石残核；石榴石的成因及来源是比较复杂的，以铁铝榴石为主，且铁铝榴石中Fe、Mg的含量较高，推测其源区母岩主要以中级区域变质岩为主。

On the other hand, what we stated in the text book is not wrong. We only want to express that not all the subduction magmatism generate andesite. Many intra-oceanic island arcs are dominated by basaltic rocks. We did not explain why because that would involve many high-level concepts like magma fractionation.

而我们在课本中的叙述也没有错，我们只是想提醒并非所有隐没作用都会产生安山岩岩浆，许多大洋中的岛弧都是以玄武岩浆为主，像是东加与马里亚纳。

It was floruit of volcanic activity in middle Caledonian between 446 Ma and 440 Ma. Mass volcanic rock was squirted, and ore bearing magma was risen by tectonic fissure, then formed a large-scale valuable polymetallic sulfide orefield.

随着构造岩浆活动的继续，能量的积聚，458.99Ma岩浆熔岩涌出地表，揭开了本区岩浆火山活动事件的序幕。446Ma～440Ma，是本区火山活动全盛时期，在本区大范围内形成有价值的多金属硫化物矿床。

The late indosinian granites in the CAQ display primarily magmatic structure,and their magnetic foliations and lineations are very different from the regional structure characterized the thrust tectonics,the emplacement mechanism also changed in different areas,all these evidence indicate that the tectonic settings is not compressional in late indosinian period when the magmatic activities developed,but a tectonic quiescence just after collision.

东西秦岭交接转换区内晚印支期花岗岩总体显示以岩浆流动构造为主，组构特征区别于作为围岩的逆冲推覆构造，不同区域的岩浆侵位过程也明显不同，表明在晚印支期岩浆活动时，区域构造已并非统一的大规模挤压推覆，而表现为碰撞造山后早期相对稳定的构造环境。

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。

Low-Ti basalt magma was obviously contaminated by continent crust, in a larger extent than high-Ti basalt magma.

低钛玄武岩浆受到陆壳物质的明显混染，高钛玄武岩浆也受到混染，但混染程度弱于低钛玄武岩浆。

All these characteristics, largely relevant to the nature of the plume-generated magma source and/or parental magmas, and magmatic evolution, can be used to identify similar rock types in natural occurrence.

这些特点与岩浆源区或母岩浆的性质以及岩浆演化条件有关，为自然界同类岩石的甄别提供了依据。

The location of rockbody and orebody is controlled by the activity center of ore-bearing magma and ore pulp,among which the most critical controlling factor is the magma conduits connecting with the activity center of ore-bearing magma and ore pulp.

4岩体的定位受含矿岩浆、矿液活动中心的控制，而最关键的控制因素还是与岩浆、矿液活动中心相连接的岩浆通道的出口。

By thorough analysis and systemic comparison of the typical deposits and magamtic plutons, especially geochemistry of different metallogenetic granites, the source formation mechanism of granitic magma, as well as including composition and character of ore-forming fluids, the author re-recognized Yanshanian magmatic activity, ore-forming fluid action and mineralization process in Southern Hunan Province, and established the conceptual model of the magmatic intrusive contact structural system.

本文通过深入剖析和系统对比矿集区内不同成矿花岗岩体的地球化学特征、岩浆物质来源、形成机制及典型矿床的成矿地质特征，重新认识了湘南钨锡多金属矿集区燕山期花岗质岩浆活动、流体作用与成矿过程，建立了岩浆侵入接触构造体系概念模型，在以下几个方面取得了一些重要进展：1。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
