The ore and the magma share similar lead isotopic features which suggests a close relations between them.
矿石和岩浆岩具有非常相似的铅同位素组成，暗示了二者的亲缘关系。Widespread magmatic rocks, the area from the east to the Himalayan period since the intensity of the magma activity times.
区域普遍分布的岩浆岩，是从加里东期至喜马拉雅期以来分歧强度的多期次岩浆勾当的产物。Once upon a time the people thought that the rocks were magma rock and it was impossible to exist boron mine bed underneath of the rocks.
从前人们认为该岩石为岩浆岩，其下不可能存在硼矿床。why are the rare earth elements so useful for classifying igneous rocks and for determining their chemical evolution?
为什么稀土元素在岩浆岩分类以及决定他们的化学演化方式上十分重要？Based upon the tectonic deformation and magma activity in the region, tectonic superposition in Yanshan epoch was discussed in this article.
本文以薛家石梁一带的构造变形和岩浆岩为研究对象，对该地区燕山期的构造叠加进行探讨。Gravels components from the Cenozoic strata are mainly composed of metamorphic rocks and sedimentary rocks with little magmatic rocks.
新生代地层中砾岩砾石成分稳定，以变质岩和沉积岩成分居多，岩浆岩很少；It indicates that overlying strata gradually break down and separation appears under the magmatic rock when the mining length increases.
研究结果表明：随着工作面的推进，覆岩逐渐垮落，岩浆岩下方开始出现离层；It is shown that the prevailing metallogenic periods of associated gold deposits of magmatic type are Proterozoic Era and Hercynian Period.
指出岩浆岩型伴生金矿床最主要的成矿期为元古代和晚古生代；That vastly increases the volume of sediments the hot rock can cook and from which methane and other carbon-rich gases can be released.
在如此宽广的岩浆岩床烘烤下的有机沉淀物大大增加了甲烷和含碳气体的释放。
