The three volcanics are of kalium alkaline series,with their chemical elements showing the same magma origin.

三种火山岩均属钾质钙碱性系列，岩石化学成分显示为同源岩浆产物。

The distribution,lithochemistry and tectonic significance of the granitoids in the Central Kunlun are preliminary discussed.

对研究较为薄弱的中昆仑地区不同期次花岗岩的区域分布规律、岩石化学特征及其构造环境意义进行了初步研究。

L. Volcanic rocks in the Ashele mine are characterized by interbedded basic and acidic pyroclastic rocks, and made up typical bimodat pattern according to 〓 features and Lithochemistry

The magmatite in the area consist mainly of granite, monzonitic granite, syenogranite and acid volcanics.

研究区出露的岩浆岩主要为花岗岩、二长花岗岩、正长花岗岩和酸性火山岩，岩石化学成分上以富铝钾、贫镁铁，且经历了较大的分离结晶作用为特征。

Petrologic studies indicate that they belong to tholeiitic series, calcalkaline series and kalibasalic series respectively.

岩石化学研究证明，它们分属拉斑玄武岩系列、钙碱性系列和钾玄岩系列。

Recent studies of abyssal peridotites show that they are not melt residues of batching or fractional melting of pyrolite directly after melt extraction of MORB. Petrological studies of peridotites from Luobusa ophiolite massif also indicate that the mantle peridotites are not simple residues of primary pyrolite either.

罗布落蛇绿岩橄的镜下观察和岩石化学资料也证明，它不是原始地幔岩经局部熔化后的残余物，而且由来自更深层的地幔过渡带的硅酸盐超高压矿物底辟上升经熔取出玄武质熔体后，再次局部熔化后的残余物。

Most of small intrusive bodies are stocks or dikes, and each of the dimension is less than 1km2 ; they are mostly granite-porphyry、porphyritic-granite、monzogranite,a small amouts of them are quartz diorite or diorite; the chemical characters are high content of SiO2、K2O and low content of Mg and CaO, on the SiO2-K2O diagram all the samples fall in the field of high-K calc-alkalic series and shoshonite series.

小岩体多呈岩株或脉状产出，出露面积多数在1km2以下；岩性主要为花岗斑岩、似斑状花岗岩、二长花岗岩，少量为石英闪长岩及闪长岩等；岩石化学成份以高硅、富碱、多钾、贫镁、少钙为特征，属高钾钙碱性系列或钾玄岩系列。

These subvolcanics, in which basalt, basaltic andesite and andesite are dominant, are petrochemically of calc alkaline affinity of subalkaline series and sodic type, and tend to have moderate low total REE, being LREE enriched.

岩石化学上属亚碱性系列、钙碱性火山岩系、钠质类型；稀土总量中低，属轻稀土富集型，稀土分布模式为右倾平滑曲线或略有正、负铕异常；过渡族元素球粒陨石标准化曲线形态呈&W&型，锶初始值为 0 。70 5398，反映物质来源较深。

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。
