查询词典 rocks

New reliable UPb age dates of the extensive Cretaceous igneous rocks in the eastern Himalayas suggest that these rocks were emplaced at about 132 Ma, and may represent the erosional and/or deformational remnants of the newly identified ComeiBunbury large igneous province.

新的可靠的锆石UPb年龄指示喜马拉雅带东部措美地区大面积出露的白垩纪火成岩侵位于132 Ma左右，代表了新近在藏南和澳大利亚南西部识别出的经历了强烈变形和深位侵蚀的ComeiBunbury大火成岩省的残余。

The samples on the right side of the table look like layered rocks. are they foliated fault rocks?

Generally speaking, the regional metamorphic rocks in this area can be divided into two groups, foliated and nonfoliated metamorphic rocks.

总的来说，这一地区的区域变质岩可以归为两大类，一类是具面理的区域变质岩，另一类是不具而理的区域变质岩。

All rocks release large fraction of argon between 300 and 700℃ except garnetiferous mica schist. The amount of argon released between 700 and 1100℃ has a positive relation to Ca/K value on the whole. The saturation implantation dose of rocks in this experiment is～10〓 ions/cm〓.

除含石榴石云母片岩氩放气峰在900℃以外，其它岩石都在300-700℃放出大部分氩气，所有岩石在1100℃以下都释放了其中大部分的氩气。700-1100℃放出的氩气量基本与Ca/K呈正相关关系。120keV氩离子注入多种岩石的饱和剂量为～10〓粒子/cm〓。

Researches to the gold-bearing quality of sedimentary and magmatic rocks show that most of these rocks have more gold content than the average of the upper crust. Further evidences are quoted to support the view that fluids exist in shallow crust have the ability resolve some gold. Moreover, in the convergent compression, deep melting of the lower lithosphere can bring some Au and mineralization materials and move up to upper crust. Regional faults, which formed in geosynclinal and diwa periods, controlled the partial distribution of intrusions and gold mineralization belts, i.e.

区域地层和岩浆岩的含金性表明，岩浆岩和大部分地层均具较高的金异常含量，而进一步的研究表明浅部地壳的流体对地层中的金具一定的溶解和搬运迁移能力；而在汇聚挤压构造体制下由深熔作用生成的岩浆可以从岩石圈深部携带部分金和其它成矿物质并迁移到地表浅部，地槽期和地洼期形成的区域断裂构造共同控制了中新世岩浆的侵入和金成矿带的分布。

The answer is obvious.Then, everyone defines their "big rocks" differently, we have to stop the hastate pace, stop, and think deeply ofour own big rocks.

想来想去我决定装着胆子开灯察看一下，鬼们一向怕亮的，我起身来了灯，战战兢兢的来到鱼缸前，看见里面的几条鱼都已经睡觉了，过滤器也正常的运转，没有异常，鱼缸里也没有冒泡泡，这个时候，那个该死的咕噜声还在不停的响，而且可以确定的是，声音就是从我的房间里发出来的。

The Mesozoic intermediate--acid intrusive rocks in Tongling area havewithin them lots of cognate inclusions, with rocks of calc--alkaline series contai- ning shallow--source inclusionswhereas those of alkalineseries containing deep--source inclusions(pyroxinite and hornblendite ones).

铜陵地区中生代中酸性侵入岩的钙碱性系列岩石中，发育同源浅源包体，而碱性系列岩石中发育同源深源包体。

The genesis and evolution of spilite-quartz keratophyre formation are discussed through studies on Sm-Nd, Rb-Sr, K-Ar isotopic characteristics of the volcanic rocks and its geological setting, and comprehensive studies of petrology, lithochemistry, trace element, REE characteristics of the volcanic rocks.

从Sm-Nd、Rb-Sr、K-Ar同位素年代学和区域地质背景以及岩石学、岩石化学、微量元素、稀土元素等方面探讨了细碧岩-石英角斑岩建造的成因及演化。

These results suggest that the diagenesis material of the Xiangshan volcanic intrusive complex was derived from crustal sources. The sources either had relatively lower maturity or had more juvenile mantle-derived igneous rocks than the exposed basement metamorphic rocks. Involvement of a small amount mantle-derived magma during the formation of the Xiangshan volcanic-intrusive complex was also possible. The diorite enclave, sub-quartzmonzonitic porphyry and lamprophyre were probably different mixing products between mantle and crust materals.

上述同位素示踪结果充分证实：相山火山-侵入杂岩的成岩物质主要为壳源，但与该区出露的基底变质岩相比，其物源区的成熟度相对较低或含有一定量的火成物质，并且不排除在其成岩过程中少量地幔物质的介入；闪长质包体、次石英二长斑岩及煌斑岩的成岩物质均含有一定量的地幔组分，可能为壳-幔混合作用的产物，只是受地壳物质混染的程度不同而已。

Following evidences indicate that lherzolite and garnet pyroxenite xenoliths in basalts are captures of mantle fragments when host magma ascending: crystallizing temperatures and pressures of cpx megacrysts and some phenocrysts in host magmas are greater than equilibrium temperatures and pressures of xenoliths; calculated REE partition pattern of assumed equilibrium melts is not comparable with that of studied host basalt rocks; olivine in xenoliths is not in equilibrium with basalt rocks.

寄主玄武岩的单斜辉石斑晶—熔体平衡温度高于石榴石二辉橄榄岩和石榴石辉石岩包体的平衡温度，单斜辉石巨晶和部分斑晶—熔体平衡压力大于包体平衡压力，寄主碱性玄武岩的稀土配分型式和所计算的与尖晶石二辉橄榄岩包体平衡的熔体的稀土配分型式不同，包体橄榄石与寄主岩浆之间的Fe-Mg交换系数低于0.30，均表明包体与寄主玄武岩浆之间不存在平衡关系，因此，包体是被寄主玄武岩浆捕虏的上地幔碎块。

Cable dampener cannot be rolled up but must be hung over the cable.

缆帆不能被卷起，必须保证处于展开状态

"This skylark is a present from my master," he says.

"这只云雀是我主人献上的礼物。"他说。
