During retrograde metamorphism with amphibolite facies, a little Zr released from rutile, which was transformed into titanite, can be supplied to zircon overgrowth. Therefore, SHRIMP U-Pb ages of retrograde overgrowth zircon should represent retrograde amphibolite facies age.

在退变质过程中，金红石退变为榍石的反应可释放少量Zr，因此退变质增生锆石U-Pb年龄应指示角闪岩相退变质时代。

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。

Sulu UHP eclogites are products of collision between South and North blocks. Subduction-exhumationof volumetrically continental materials gave rise to formation of diverse UHP metamorphic rocks, and simultaneously titanium mineralization with rutile as principle ore mineral.

苏鲁地区超高压榴辉岩是华南-华北板块碰撞的结果，巨量陆壳物质俯冲-折返形成了多样式的高压-超高压岩石，与此同时也发生了以金红石为主要矿石矿物的钛成矿作用。

The faults and the apophyses are main ore-control factors. Devonian and Carboniferous Systems are target horizons and Guwanliang-Tongtianping-Huanggeda fault is the target structure for further Au exploration in the district.

今后金矿勘查工作以泥盆系和石炭系为重点找金层位，古湾梁－通天坪－黄屹塔断裂和印支期岩枝内外接触带为重点勘查靶区。

And now we lookin' like pimps In my gold Trans-Am.

现在我们看着的像皮条客我在金跨岩。

Using the neutron activation analysis method, the author studied the trace element characteristics of silicified and limonitized quartz sandstones, diabases, limestones and pyrite in the Laozhaiwan gold deposit, and analyzed the relationships between the elements. The results show that the accompanying elements of Au in the study area can be used to guide the ore-prospecting work.

采用中子活化分析方法测试了老寨湾金矿区内的硅化褐铁矿化石英砂岩类、辉绿岩类、灰岩类和黄铁矿样品的微量元素特征，并利用元素地球化学研究方法对元素间的相关关系进行了分析，结果表明，在该地区可以利用金的伴生元素来指导找矿。

It is concluded that lead source of all the nine deposits studied in this paper can be located to the specific position by the comparison method. Only by the comparison of Pb compositions of ore with those of the other rocks, the studying conclusions may be trustworthier.

结果表明，与岩浆活动有关的夕卡岩型和岩浆热液型矿床有两种情形，一种是纯岩浆源铅，另一种是部分围岩铅也参与了成矿；热水沉积矿床的铅主要来自深部；改造型矿床的铅主要来自围岩；像留龙金矿这样看似与岩浆活动关系密切的矿床，对金而言，是改造成矿的产物。

Based on the analysis of deposit genetic type in the metallogenic belt,the metallogenic series has been put forward,that is volcanic-subvolcanic hydrothermal and porphyry type Au-Cu and Mo-Pb-Zn-Ag metallogenic series .

在分析成矿带内不同矿床成因类型的基础上，建立了该成矿带的成矿系列：火山、次火山热液-斑岩型金铜及钼铅锌银成矿系列。

These deposits—whose size and output are unknown—were originally discovered by Kimberlithic Searches, the Zimbabwean exploration arm of the world's main diamond-producing company, De Beers.

这些钻矿存量—规模及产出都不为人知—最初是由世界上主要的钻石生产企业戴比尔斯的津巴布韦勘探部门&金伯利岩搜寻&发现的。

Chinese Academy of Sciences , Beijing 100029 , ChinaAbstract : The content s of such platinum-group element s as Ir , Ru , Rh , Pt and Pd in J ianguo basalt s and Wula 2 hada Mg- high andesites were determined using ICP-MS after a nickel sulfide fire assay preconcent ration.

采用镍锍火试金法结合 ICP-MS 分析了碱锅玄武岩和乌拉哈达高镁安山岩样品中的 Ir 、 Ru 、 Rh 、 Pt 和 Pd 的含量。

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。
