地壳

The Earth's crust, or Continental crust, is the outermost solid land surface of the planet, is chemically and mechanically different from underlying mantles, and has been generated largely by igneous processes in which magma cools and solidifies to form solid land.

地球的地壳是地球最外层的硬质土地表面，在化学性和物理性都与下一层内的地幔不同，是由于火山爆发的岩溶冷却之后凝固形成的大范围的硬质层土地。

这里曾经孕育了华夏民族的祖先，建立过炎黄子孙的家园，亿万年地壳变迁和历代战乱，灾害侵蚀，使它支离破碎，尤以定西中部地区成了祖国最贫瘠的地方之一，但蕴含着无尽的宝藏。

It constitutes 21% of air and more than 46% of Earth's crust, where it is the most plentiful element.

Petrological and geochemical characteristics of alkali-rich porphyries suggest that magmas might not be generated from subducted oceanic slab, but likely from the base of thickened crust, corresponding to eclogite-facies.

富碱斑岩产出的地质背景及岩石学和地球化学特征表明，富碱斑岩并非起源于俯冲的大洋板片，而是源于加厚地壳的底部，源区为榴辉岩相岩石。

The δ^34S values of ore minerals vary slightly from -3.1‰ to +0.7‰ with an average value of -1.1‰ and the δ^34S values of the ore-bearing porphyries are -1.4‰ and -1.5‰, indicating that sulfur is mainly derived from the magma of porphyry.

雪鸡坪铜矿S，Pb同位素组成共同指示成矿物质主要来自于深部岩浆，这种岩浆可能主要起源于俯冲洋壳板片的部分熔融并受到少量地壳物质的混染。

A systematic study on S and/or Pb isotopic compositions of the copper-bearing porphyries, ore minerals and andesite of the deposit shows that S isotopic compositions of ore minerals are similar to those of porphyries.

矿石矿物（208Pb/204Pb=37.917~38.230，平均值38.075；207Pb/204Pb=15.528~15.614，平均值15.571；206Pb/204Pb=17.929~18.082，平均值17.981）与矿化斑岩(208Pb/204Pb=37.832、37.883，207Pb/204Pb=15.529、15.538，206Pb/204Pb=17.906、17.910)以及安山岩(208Pb/204Pb=37.816~37.884，207Pb/204Pb=15.549~15.562，206Pb/204Pb=17.845~17.919)的初始铅组成基本一致，变化范围较小，表明三者具有相同的来源；在铅构造模式图上，所有样品铅同位素均位于造山带演化线上或附近，在铅同位素源区判别图中，均落入造山带和下地壳区域，这表明Pb主要来源于壳幔混合。

The limestone precipitates in layers over time and can grow more than 30 feet (9 meters) high.

地壳中的花岗岩随时间流逝缓慢析出，可以长到30英尺(9米)高。

A tear in the crust forms and propagates as fast as a bullet shot from a gun.
