A luminous spot on a lunar halo .A bright spot sometimes appearing on either side of the sun, often on a luminous ring or halo .

矿石部分呈块状，部分呈浸染状，围岩中并有矿物的浸染晕存在。

The calculating results indicate that surrounding rock initial stress has an obvious influence on interior force of invert center, interior force increases with the vertical force increasing in both side of invert center, and decrease with horizontal force increasing in interior side , unchangeable in outer ...

计算结果表明，围岩初始应力场对仰拱受力有明显影响，随着竖向压力的增大，仰拱中心的内、外侧应力均增大；随着水平压力的增大，仰拱中心内侧应力减小、外侧应力基本不变；减小复合衬砌结构中初期支护厚度以及变刚性接头为柔性接头均会改善仰拱受力。

The kaolinitic tonsteins, the kaolinitic rocks not adjacent to coals and soft kaolin were studied in this project. The studies show that the materials forming the kaolinite come from the volcano ashies, terrigenous transportation and the solution precipitation of the rocks surrounding the weathering coals.

本项目对我国煤系夹矸高岭岩、煤层不相邻高岭岩和煤系软质高岭土进行了详细研究，认为成矿物质主要来源于火山灰、陆源搬运产物以及煤层围岩物质的溶解沉淀。

Rock mass deformation and failure in working face caused by underground mining lead to mining-induced fracture ,which is the source of a series of mine disasters.

地下矿床开采引起采场围岩变形破坏产生采动裂隙，采动裂隙是矿山一系列灾害的根源，研究矿山采动裂隙岩体的地球物理场特征，提出可行的地球物理方法对裂隙岩体实施高精度高分辨率探测，对于防治矿山灾害发生，保障矿山安全，具有重要的理论意义和实际应用价值。

Rock mass deformation and failure in working face caused by underground mining lead to mining-induced fracture, which is the source of a series of mine disasters. The research on geophysical characteristics of mining-induced fracture rock mass and feasible geophysical techniques with high accuracy and resolution detection on mining-induced fracture rock mass are meaningful theoretically and practically for the safety of coal mines and the prevention of mining disasters.

The gold lodes in the Dongwujiazi gold deposit are mainly hosted in the metamorphic complex of the Archean Xiaotazigou Formation,Jianping Group.

东五家子金矿矿脉主要围岩为太古宙建平群小塔子沟组变质杂岩，矿床距燕山期石英二长岩南约6km。

The characteristics of REE in the ores is different from those in country rocks and magmas, the hydrothermal fluids shows the features of mantle origin.

矿石的稀土元素组成与近矿围岩和侵入岩中的稀土元素组成有比较明显的差异，热液具有幔源特征。

The chemistry of mine drainage can be affected by many factors, including the type and abundance of metal-bearing sulfides in ore and wall rock, and smelting process.

在碳酸盐岩地区的矿山环境中，由于其矿石类型、围岩类型以及选矿工艺的不同形成的矿山水体常呈中性，甚至碱性。

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。

When the sandstones are surrounded by carbonates or thick mudstones, then high carbonate contents will be found in the sandstones.

当砂岩层围岩为碳酸盐岩或厚的泥岩时，在砂岩层内部易形成高碳酸盐含量、胶结作用强烈的含碳酸盐胶结物。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
