The rutile-hosted rocks are metamorphic rocks with amphibolite facie, but more work should be done to discuss features of their protolith.

这一化学特征显示了与岩相学观察相一致的结果，即富含金红石的岩石为透闪石含量偏低的直闪岩类。

The three ore belts of Kubusu gold deposit all were preduced in dikes of diorite porphyrite and granodiorite porphyry.

库布苏金矿床的三个金矿带均产于闪长玢岩和花岗闪长斑岩内。

These two ores have contrasting mineral associations: anthothyllite + plagioclase + rutile + magnesiohornblende + alkline fledspar for red ore and anthothyllite + phlogopite + epsode + Rutile for black ore.

根据岩相学观察，认为红色金红石矿中存在如下方向的反应：镁角闪石+碱性长石→直闪石+／-斜长石+／-金云母，斜长石很可能只是过渡相，反应最终将形成直闪石+金云母。

According to the geochemical data, the formation of mantle peridotite might be: during the spreading of ocean floor, the MOR mantle underwent variable degrees of partial melting and formed the depleted mantle peridotite with podiform chromitite; during the spreading of ocean basin, intra-ocean subduction happened, REE and LILE rich fluids containing water derived from the subduction slab migrated upwards and metasomatism happened to peridotite relic.

康金拉矿区的地幔橄榄岩的地球化学特征反映了其形成过程的复杂性，表现为：洋底扩张期间，扩张脊下的MOR型地幔的经历了不同程度的部分熔融，形成了亏损地幔橄榄岩，该地幔橄榄岩中赋存了来自深部的豆荚状铬铁矿。

The deep origin of Kangjinla podiform chromitite is suggested by: that for the Kangjinla chromitite and the mantle peridotite rocks, the compositions of the chrome spinel, olivine and clinopyroxene are rather different, which indicates that the chrome spinel in the chromitite is neither the simple concentration of that in the host rocks nor with certain genic relation with mantle peridotite. Though the chromitite might be exotic for host rocks, both of them were carried from deep mantle to the shallow place by mantle plum.

康金拉铬铁矿石与矿体围岩地幔橄榄岩的铬尖晶石、橄榄石和单斜辉石等成分方面明显不同，认为矿石铬尖晶石并非是由副矿物铬尖晶石富集而成，与地幔橄榄岩也不存在成因联系，认为豆荚状铬铁矿床对于近矿围岩地幔橄榄岩而言为外来体，但两者可能均是由地幔深部被地幔柱带到上部。

According to the research of the paper, the "migmatite" of the Sizishan Formation, Xingdong Group distributed in northern Xiao Hinggan Mountains should be a suit of gneissic quartz monzonitegranite intrusions. Their whole rockmineral Rb-Sr isochronic dating is (482±19) Ma, indicating that an Caledonian magmatic events existed in the giant granitic belt of the Xiao Hinggan Mountains.

研究表明，分布于小兴安岭北部金林林场的兴东群四子山组&混合岩&为一套片麻状石英二长岩-花岗岩侵入体，岩石全岩-矿物Rb-Sr等时线年龄为(482±19) Ma，这表明小兴安岭巨型花岗岩带中存在早古生代岩浆事件。

According to cpx-melt equilibrium pressure, the xenoliths types and simulating calculating of host rock REE partition pattern, source of sodic basalts is garnet lherzolite mantle, and the source of potassic basalt is metasomatic fluid altered phlogopite-containing garnet lherzolite mantle. For the alkaline basalts to sub-alkaline basalts, the melting degrees of the source rocks are 4%～15%.

根据单斜辉石—熔体平衡压力计算、所携带的包体类型及玄武岩稀土元素配分曲线的非实比部分熔融定量模拟表明，钠质玄武岩的来源为石榴石二辉橄榄岩源区，五大连池钾质玄武岩的源区是被交代的含金云母石榴石二辉橄榄岩源区，研究区碱性玄武岩到亚碱性玄武岩是石榴石二辉橄榄岩源区经4％～15％部分熔融程度的产物。

In addition, native gold and Si-bearing native copper and SiC that is an indicator of high pressure were recognized in picrites. This is the first documented case of the native gold and native copper enclosed in olivine phenocrystals, which will play a key role in studying the compositions of mantle plume.

此外，还对两个苦橄岩进行了重矿物分选，分选出高纯度的自然金和含Si的自然铜以及高压指示矿物碳硅石，并在薄片中发现了自然金和自然铜被包裹在橄榄石斑晶的现象，这是世界上首次在橄榄石斑晶中发现自然金和自然铜，对进一步研究地幔柱的物质组成具有要的科学意义。

The gold ore deposits and prospects occur within the nearly NW-striking faults in the carbonate rocks of the cover of the Yangtze block,Proterozoic metamorphosed quartz diorite of basement of Yangtze block and Mesozoic quartz porphyry in western Shimian, Sichuan Province.

四川石棉西部地区金矿床和矿点分布在扬子地块盖层碳酸盐岩和基底元古宙变质闪长岩以及中生代石英斑岩中的北北西和北北东走向断裂中。

According to a vast amount of geochemical research works on gold deposits , some sedimentary-exhalation type gold deposits have been distinguished. In addition, the close spatial and temporal relation of sedimentary-exhalation to the Archaean lode gold deposits that have distinct characteristics of epigenetic mineralization also has been discovered.

大量的金矿床地球化学研究工作已识别出一些沉积喷流型金矿床，此外还发现即使是具有明显后生成矿特征的太古宙绿岩带中的脉状金矿床也显示出其同沉积喷流作用密切的时空关系。

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。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
