矿体

Gravitative differentiation occurred to the magma in the magma chamber, resulting in the increasing of basicity in the upper intrusive lithofacies and the better ore potential, and subsequently copper and nickel sulphides were formed by the ore magma injection.

熔浆在岩浆房发生了重力分异作用，致使其上侵岩相基性程度逐渐增高，含矿性也越来越好，最后由矿浆贯入形成了铜镍硫化物矿体。

Chemical analyses of ores sampled from different elevation at the representative Zoujiashan uranium deposit indicate that Fe〓O〓, FeO, MgO and P〓O〓 increase evidently with depth which is related to alteration of haematite, chlorite and apatite, Na〓O and Na〓O+ K〓O also increase with depth, reaching a maximum of Na〓O at 911 meters below the surface, which suggests alkaline alteration increases downwards. At depth of 90 meters below sea level, where the boundary of the two cycles of the volcanic rocks is located, CaO reaches the maximum, representing maximum of alteration of fluorite.

对典型矿床不同富集标高矿体的化学全分析结果表明：随深度增加，Fe〓O〓、FeO、MgO及P〓O〓的含量有明显增高的趋势，这与赤铁矿化、绿泥石化及磷灰石化有关；-90m标高的CaO含量最高，达17.67％，反映这一部位的萤石化最发育；Na〓O及Na〓O+K〓O的含量由浅入深也存在明显的增高趋势，且Na〓O的含量在911m深处为最高，这充分显示碱交代作用从上到下有增强的趋势，而钠长石化在911m处最强烈。

The ore bodies are characterized by the sedimentary and post-sedimentary hypothermal overprint mineralization.

矿体具明显的沉积和后期热液改造特征，硫同位素δ(34S)值为-0.11‰~11.10‰，平均为5.73‰，接近大气降水的δ(34S)值。

The ore structural fabric mainly behaves in form of filling action with minerals such as pyrite, chalcopyrite, salenite, blende and electrum, which typomorphic feature shows a hypothermal pattern of metallogeny.

矿区内矿体规模巨大，矿石组构主要为以充填交代作用为主，矿石矿物主要为黄铁矿、黄铜矿、闪锌矿、方铅矿和银金矿。而且矿物的标型特征显示了低温成矿的特点。

Limonitization is the ore finding sign in the district. Gold ore bodies are hosted in gray - purple feldspar sandstone.

金矿体赋存在三叠系黄褐、灰紫色长石砂岩中是我省金矿床类型中较为少见的一种类型。

The ore body is related to the Early Yanshanian magmatic activity in time and space.

矿体在时间和空间上与燕山早期岩浆活动有一定关联。

The formation of ore bodies is controlled by stratum, structure, magmatic rocks, physical-chemical conditions and so on.

矿体的形成受地层、构造、岩浆岩及物化条件等综合控制。

Boron deposits of eastern Liaoning occur in a suite of Early Proterozoic metamorphic rocks, with boron orebodies existent in magnesian marble.

辽东硼矿床产于早元古代的一套变质岩内，硼矿体赋存于镁质大理岩中。

It can be concluded that: First,primary deposit and placer deposit are two main deposits in this origin;Second,the primary deposit formed at hydrothermal stage and mesothermal stage between Presinian and Cretaceous;Third,the feature of ore body is wide and scattered on distributing,small on scale;Four,the storage capacity of the crystal is very abundant,its quality is fine,depth of burial is s.

通过对江苏东海区域成矿地质条件以及含晶石英脉成群成带分布规律的研究，得出以下结论：①该区水晶矿床为原生矿、砂矿两种类型；②水晶原生矿形成于前震旦纪以后到白垩纪以前的高、中温热液期；③矿体具分布广、规模小、分布散等特点；④东海水晶储量丰富、品位极高、埋藏浅，具有很好的开发利用前景。

The Dayingezhuang gold deposit in the Jiaodong area,Shan dong Province,is a hidden(to a burial depth of more than 250 m from the surface),mesothermal,alteration-type gold deposit in a fractured zone.

大尹格庄金矿床为一隐伏的(埋深距地表250m以上)中温热液破碎带蚀变岩型金矿床，现已经有十几年的开采历史，从目前验证钻孔剖面来看，矿体在深部有再富集的趋势。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
