西昆仑塔什库尔干构造混杂岩带由古元古界基底岩片、震旦纪大陆板内裂谷玄武岩岩片、奥陶-志留纪复理石岩片、石炭-二叠纪火山弧岩片及高压变质岩片组成。

When silica content reaches 45-53 %, basic rocks become the name of this type of igneous rock in which the gabbro is the typical intrusive rock which are composed of pyroxene and calcium plagioclase, whereas basalt is the equivalent extrusive rock.

当岩石中SiO2含量在45～53%之间时，称这类火成岩为基性岩。辉长岩就是这类岩石侵入岩的典型代表，其中矿物成分为辉石，钙长石，而基性的喷出岩则称之为玄武岩。

Basalt have importance meanings on deduce the Earth's mantle material composition, analysis tectonic environment and the geosphere deep dynamics research.

摘要玄武岩在反演地幔物质成分、分析构造环境和岩石圈的深部动力学研究中具有重要意义。

The contents of Ni, Au, Mo, W of the deep-seated xenoliths and their host basalts from eastern China are inhomogeneous. The contents of Ni, Au are highest in the mantle-derived xenoliths the contents of Mo, W are highest in the basalts and the mafic granulite, and the leptite and the granitoids, respectively.

地球深部包体中镍、金、钼、钨等成矿元素的含量是不均一的，镍和金在地幔岩包体中含量最高，铝在玄武岩及镁铁质麻粒岩包体中最高，而钨在长英质麻粒岩和花岗岩类包体中含量最高。

They are clay, mud shale, gravel, oil shale, mudstone, schist, basalt, limestone, gritstone, dolomite, breccia, granite, and quartzite. We give the feature curve and distribution feature equation of these rocked landslide.

本论文分别对不同滑体岩性，包括从软到硬的粘土、泥页岩、砾类土、油页岩、泥岩、片岩、玄武岩、灰岩、砂岩、白云岩、角砾岩、花岗岩、石英岩十三种具有代表性的岩土体的滑坡推力和剩余抗滑力进行了模拟分析，给出了它们的滑坡推力和剩余抗滑力分布特征曲线，分布特征方程。

Three different kinds of clinopyroxenes were found in ankaramite and basalts: big phenocryst, small phenocrysts and microcrystals in groundmass respectively.

北塔山组富辉橄玄岩和玄武岩中存在着三种类型的单斜辉石：大斑晶辉石、小斑晶辉石和基质辉石。

350Mpa . And they are widely suitable for primary crushing of many kinds of mining and rock such as many kinds of ores, concrete, fireproof material, bauxite, quartzite, corundum, perlite, ironstone, basalt, etc.

它们被广泛适用于初级破碎多种采矿和摇滚等多种矿石，水泥，耐火材料，铝矾土，石英，刚玉，珍珠岩，铁矿石，玄武岩等

Through K-Ar isotope age study in pillow basalt,has gained the isochrone age is139Ma.The age is the formation age of pillow basalt.

在枕状玄武岩中获得K－Ar同位素年龄为139Ma（测试单位：宜昌地质矿产所同位素室），因此确定其时代为晚侏罗世晚期。

On the basis of summarizing scientific goals of lunar exploration and analyzing distribution characteristics of landing sites, the authors chose three craters of Copernicus, Kepler, and Aristarchus in KREEP rock distribution area as candidate landing sites.

克里普岩对于研究月球的起源和演化有重要意义，但由于该岩石被玄武岩所覆盖，难以利用轨道探测器开展全面深入的研究。撞击坑是研究月表以下物质成分的窗口，在克里普岩区选择条件合适的撞击坑开展软着陆探测有助于对克里普岩的深入研究。

The hight cliff and large landside were developed. Now the Isle becomes a remmant of volcanic neck and a spectacu...

普遍的悬崖绝壁和近岸区海底广布的玄武岩石块堆积充分证明了目前的南碇岛是一个典型的蚀余火山颈。

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。
