The relationship of ore-forming fluid salinity-aqueous cation lg demonstrated that water-rock reaction was also one of the potential gold deposition mechanisms besides mixing with meteoric water. All of these were consistent with that sericitization and pyritization hydrothermal alteration were extensively/intensively distributed (as high as 33%), gold grade linearly correlated with degree of alteration,∑REE depletion and δ〓O enrichment

成矿流体盐度-液相主要阳离子组分1g演化规律研究表明，除与大气降水的混合-稀释外，水-岩相互作用也可能是造成金沉淀的重要因素，这与本文所研究金矿床中绢云母化、黄铁矿化等热液蚀变广泛发育(可高达33％)，Au品位与热液蚀变程度、REE亏损量及δ〓O富集规模表现出较为明显的线性关系等一系列地质事实相吻合

Gold mineralization is controlled by the near E-W-trending fault. The metallogenesis belongs to cataclastic altered rock type, with characteristics of low grade and large amount of ore, which is the first discovery in western Liaoning.

通过钻探证实，金矿化受近东西向断裂构造控制，矿化类型为碎裂蚀变岩型，具有低品位、大矿量特点，在辽西地区属首次发现。

The results showed that:①the crystalline phases are mainly the cuspidine, wollastonite and gehlenite with nepheline, fluorite and olivine also found in some samples under the experimental conditions;②with the bacisity and CaF_2 content increased, crystalline proportion of mold flux rises .

熔融保护渣在MoSi2高温电阻炉内以2℃/min降温速率冷却至室温，制成薄片，采用岩相显微镜分析保护渣的结晶矿相·结果表明：在本实验条件下，结晶矿相主要有枪晶石，硅灰石，黄长石，个别渣样有霞石，萤石，橄榄石；增大保护渣碱度，能促进保护渣结晶；随着渣中CaF2，Na2O，K2O和Li2O质量分数的增大，保护渣结晶化率增大；随着渣中Al2O3，MgO，BaO和MnO质量分数的增大，保护渣结晶化率减小

The mineralization of a number of deposits of this class were associated with certain types of host rocks, but the most were formed by the unmixing of H2O-CO2-salt fluid with very high salinities and the mineralization is commonly linked to potassic alteration.

部分该类矿床的形成与一定的主岩类型有关，而多数矿床可能由高盐度H2O-CO2-盐混合流体的不混溶作用形成，且矿化通常与钾化有关。

So it has more important significance that how to recognize silicified rock from host rock and the extent of silicify.

因此，如何正确地识别硅化岩石与原岩，以及硅化的强弱对于找矿有着重要意义。

The Shengmikeng vein-type lead-zinc deposit is located in Huanggangshan volcano-tectonic depression of the Mesozoic volcanic belt in Northern Wuyi.The ore featured by veinlets and disseminations is hosted both inside the fault zone in the upper Jurassic Ehuling ignimbrite and the potassic trachyte porphyry.

摘 要：生米坑铅锌矿床位于北武夷中生代火山岩带的黄岗山火山盆地内，已知铅锌矿体呈脉状产于侏罗系上统鹅湖岭组流纹质熔结凝灰岩的断裂内，或呈细脉——浸染状分布于钾质粗面斑岩内，发育钾长石化、绿泥石化、硅化等蚀变。

The Yiarmand gold deposit occurs in hydrothermally eruptive breccia of the 2nd Member of Lower Carboniferous Dahalajunshan Formation and its underlying arsenopyritized and pyritized tuffaceous clastic rocks,and the ore forming process can be divided into hydrothermally eruptive and sedimentary stage and metasomatic stage.

伊尔曼德金矿床赋存于下石炭统大哈拉军山组第二岩性段硅化热液喷发角砾岩及其下伏上泥盆统吐呼拉苏组毒砂黄铁矿化凝灰质碎屑岩中，成矿作用可分为热液喷发沉积期和热液交代蚀变成矿期。

The formation of high-grade ore body has undergone a complex process.

在复杂的成矿过程中，矿床所形成的地质构造、地球物理及地球化学等特征构成清晰的找矿要素，从不同尺度和有效性的要素系统，构建出以&中基性钙碱性火山碎屑岩+高极化高重力+多级复杂褶皱构造+硅化-绿泥石化+孔雀石化&为核心的矿床综合找矿模型。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
