查询词典 rocks

We divide the evolution of becoming rocks into four periods: early region's metamorphic process and mixed lithifaction,sedimentation and becoming rocks process in middle and late Proterozonic Era and in the Paleozonic Era,trasformation process of burial hill layers in earth shell'uplift period in the Mesozonic Era, and transformation process to burial hill in the Cenozonic Era.

从地质特征和岩石化学两方面论证了矿区火山岩以基、酸性碎屑岩互层为主要特点，并构成典型的双峰式火山岩组合

The variations of iron species not only affect the lithological properties of sedimentary rocks, such as color, but also reflect the paleoenvironments of the sedimentary rocks.

岩石中的铁元素及其化学种是影响其岩性特征，包括颜色的一个重要因素，并进一步影响遥感技术应用的图像解译和谱段选择。

The Dahalajunshan Formation dominated lithologically by calc-alkaline volcanic rocks constitutes a complete island arc volcanic sequence; whereas the Aikendaban Formation with dominance of alkaline-subalkaline volcanic rocks belongs to shoshonitic sequence formed in the extension of collision-orogeny.

大哈拉军山组火山岩以钙碱性系列为主，构成了一个完整的岛弧演化序列；艾肯达坂组火山岩以偏碱性-碱性系列为主，属于典型的碰撞造山伸展期的橄榄安粗岩系。

The seismic reflectance signatures of the Carboniferous volcanic rocks in the study area are divided into four types, including lobate/wedge reflection, tabular reflection, arc reflection, and mound/mushroom reflection. Based on previous studies and detailed well-seismic correlation, the lithofacies of volcanic rocks corresponding to different seismic reflectance signatures are recognized.

将该区石炭系火山岩体的地震反射特征划分为以下4种：舌状或楔状反射、板状反射、弧状反射、丘状或蘑菇状地震相反射特征；结合前人的研究成果和详细的井震对比，确定了不同的地震反射特征所对应的火山岩岩相。

Recent studies suggest that the Mesozoic granitoids and the contemporary mafic and ultra-mafic rocks from the North China block and Dabie-Sulu orogenic belt have the similar Sr, Nd isotopic characteristics, and many of the granitoids and volcanic rocks exhibit some features of adakites.

近年来的研究证实，华北地台和大别—苏鲁造山带的中生代花岗岩与同时代的镁铁质超镁铁质岩有类似的Sr、Nd同位素特点，许多花岗岩和火山岩还具有类似埃达克岩的地球化学性质。

During the subduction and collision of Yangtze and Sino-Korean craton in Triassic period, they all subduced into mantle depth, due to the granite was relative poor in water and denser than sedimentary rocks, the kinetics rate of metamorphism of granite was much more slow than that of sedimentary and mafic volcanic rocks.

即在扬子板块与中朝板块三叠纪俯冲—碰撞过程中他们一起进入到地幔深度的超高压环境，但由于花岗片麻岩的原岩相对于副片麻岩的原岩明显贫水且结构致密，其中发生变质作用的动力学速度明显慢于沉积岩或基性火山岩中的动力学速度。

The Cretaceous sedimentary rocks were baked by the basaltic lava flow erupted in the Early Miocene, contracting in volume owing to loss of water contained mainly in the clays of the clastic rocks, and thus forming the columnar jointing. According to the occurrences of jointing and the sedimentary strata the authors calculated the two different rotations of the Mellit block: the block tilted toward 338° for 18° from Late Cretaceous to the beginning of Miocene, and tilted toward 138° for 18° since Miocene.

可以合理地假定柱状节理在形成时是垂直于大地基准面的，根据柱状节理和沉积岩层的产状，笔者计算出Mellit地块的两期旋转事件：自晚白垩世初期到中新世初期该地块向338°方向倾斜了18°，而自中新世以来又向138°方向倾斜了18°。

As you have known, the metamorphic rocks make up the third great family of rocks

正如你们所知道的那样，变质岩是岩石家族中3大岩类中的一类。

Rocks that have changed due to temperature and pressure increases are metamorphic rocks.

岩说，有改变，由于温度及压力增加是变质岩。

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。
