黔西南水银洞金矿是一特大型富金矿床，矿体成群多层、顺层产于龙潭组地层中，通过系统研究水银洞金矿赋矿地层岩石及矿石的显微组构特征，以及与金矿成因联系密切的硅化及黄铁矿化特征，均显示为同沉积—成岩特征，共同指示水银洞金矿沉积—成岩后期轻微改造的成因机制。

Veined,stockwork and alteration-sheathed gold ores have been found in the area,belonging to four genetic types:the volcanic hydrothermal ores related to early—middle Carboniferous volcanism; subvolcanic hydrothermal ores related to intermediate—acidic porphyry intrusions; hydrothermal ores to the granitic intrusion and dynamo- hydrothermal ores related to regional dynamic metamorphism along the faults.

矿石类型有含金石英大脉型、石英网脉型和蚀变岩型。矿床成因类型有4种：一为火山热液型，其成因与区内早—中石炭世火山作用有关；二为潜火山热液型，与中酸性斑岩体侵位有关；三为岩浆热液型，与花岗质岩浆的侵位有关；四为动力变质热液型，沿断裂带分布于蚀变玄武岩中，系区域动力变质作用的产物。

It is an uncontinuous plane between the grey gneisses and Jingangku formation complex undergone later many strong deformations, especially the near-horizontal ductile shearing.

在恒山和五台山区大体上金岗库岩组的不同岩性或层位与灰色片麻岩相接触，受到后期多次强烈的构造改造，特别是近水平的韧性剪切使二者之间呈一不连续面，年轻的表壳岩覆盖在老片麻岩系之上，属剥离断层性质，应为低角度的大型正断层。

Gold mineralization in the area occurs in Devonian and Carboniferous Systems including three Au mineralization belts, that is the north, middle and south belts. Au deposits or occurrences are located in the inner and outer contact zones of Indosinian apophyses and EW faults.

区内金矿化赋存于泥盆系和石炭系中，构成北、中、南3条金矿化带，金矿床定位于EW向断裂和印支期岩枝内外接触带中，断裂构造与岩枝是主要控制因素。

In addition,"water" concentrations of inclusions rutiles are higher than intergranular ones, and the rutiles from fresh eclogites hold more "water" than those from retrograded eclogites, implying that the retrograded fluid might not be derived mainly from release of structural hydroxyl during exhumation.

不同赋存状态金红石结构水含量的对比研究显示，粒间颗粒高于包裹体者，退变质榴辉岩略高于新鲜榴辉岩者，表明退变质流体可能并不主要来源于结构水的减压释放。

They are:①completed total 8 000 km long natural seismic profiles cross the northern boundary and central part of the plateau, identified several deep-cut lithospheric faults and low velocity and low density bodies under the central part of the plateau related to Cenozoic volcanic eruption, the Tarim block subducted beneath the Altun Mts;②found the evidence that the Altyn Tagh fault formed in 220～240 Ma and at least 400 km sinistral offset since, and determined quantitatively deformation in Cenozoic;③discovered 350 km long high-ultrahigh pressure metamorphic belt in the south border of the Qilian terrane,which brobably represented the Early Paleozoic boundary between the North China and Yangtze plates;④according to new discoveries of caledonian ophiolite,granite are subducted complex established paleo-collision orogenic framework of northern Qinghai-Tibet plateau;⑤proposed a new model .

本文展示了中法1995～2000年青藏高原北部地学研究的如下主要新进展：①完成8 000 km长的青藏高原北部及中部天然地震岩石圈探测剖面，确定若干条岩石圈断裂，发现与新生代火山喷发有关的青藏高原中部深处的低速、低密度体，塔里木地块俯冲于阿尔金山之下；②提出阿尔金断裂形成于220～240 Ma和左行平移400 km的科学依据及确定其新生代变形量；③确定祁连南缘350 km长的高压-超高压变质带，提出其可能代表早古生代时期北中国板块与扬子板块之间西部界限的新认识；④根据加里东期蛇绿岩、花岗岩及俯冲杂岩带的新发现，初步建立了古碰撞造山格架；⑤提出高原隆升的&地幔底辟和内向陆内俯冲&的新假设。

The main rock types are two mica quartz schist and plagioclase amphibole schist.

老湾金矿床赋矿围岩是经历过多次韧脆性剪切改造作用的中元古界龟山组变质岩系，主要岩石类型为二云石英片岩和斜长角闪片岩。

现有资料发明，金伯利岩体上部富金刚石，而往深部品位变贫且质量差，在一个岩管中往往中部富而边部渐贫。

Abundant materials for karstification in Jinfoshan are provided by medium or thick-bedded blocky limestone and biologic clastic limestone of the Lower Permian system.

下二叠统的中厚层块状灰岩及生物碎屑灰岩给金佛山岩溶作用的发生提供了坚实的物质基础。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
