In the roaring scalding fulgurites, in the blusterous bleak storm, you will all realize that the god deceived you.

在咆哮著的炙热的岩浆中,在怒吼著的阴冷的寒风中,你们会明白上帝欺骗了你们

Ma,and lithosphere delamination and thermal exhumation during 196~163?Ma.The rapid thermal exhumation,co\|occurred with extensive regional metamorphism and intermediate\|acidic magmatism,implied that the subducted slabs had broken off and delaminated.The p T t path of UHPM consists of two curves,i.e.,a barrette\|like curve reflecting the process of cold slab subduction and exhumation,and a crescent curve representing the thermal exhumation after slab breakoff.

通过全面评述该区变质岩研究成果,作者认为:超高压变质岩的形成和剥露经历了240~200 Ma的板片冷俯冲冷折返和196~163 Ma的岩石圈拆沉热折返;热折返伴随了广泛而强烈的区域变质作用和中酸性岩浆活动,指示板片断离拆沉的发生;超高压变质岩p-T-t轨迹由两部分组成,即反映板片冷俯冲冷折返过程的发夹状曲线和指示板片断离拆沉热折返过程的新月形曲线。

火山口喷起的熔岩浆映出了两个探险者的身影。

During Paleogene period 48~ 32 Ma in northeast China, one or several at least basaltic magma eruption events occurred each 1Ma; it is verified by K - Ar chronometric age data.

在中国东北地区始新世48~32Ma期间,每1Ma内至少发生一处或数处玄武岩浆喷发火山事件。K—Ar测年数据记录了其活动的存在。

All of these characteristics indicate that the magma which produced the garnet clinopyroxenite was formed mainly by melting of the clinopyroxene from the mantle source with residual garnet. The phases of the rock before exhumation might have been clinopyroxene + garnet.

这些特点表明形成石榴单辉辉石岩的岩浆为地幔源区残留石榴石、主要熔出单斜辉石的高程度部分熔融的产物,折返前可能由单斜辉石+石榴石相组成。

The granite body in the Jiangjunzhai tungsten deposit is a compound rockmass, which has the features of crust-derived type granite and is the product of comagmatic evolution.

岩石学和岩石地球化学研究表明,将军寨钨矿花岗岩体为一复式岩体,是同源岩浆演化的产物,具有壳源花岗岩的特征。

These dikes are temporally and spatially associated with the gold deposit,and they have the same Pb isotopic compositions,which suggest the comagmatic activities in the same tectonic background.

区内脉岩与金矿在时空上密切伴生,Pb同位素组成接近,应属于同一构造同源岩浆活动的产物。结合前人C-H-O-流体包裹体研究成果,表明胶东金矿化中有幔源流体参与的成分。

Cryptoexplosive breccia and cryptofelsite was derived from comagmatic source, as the products ofdifferent phases of a certain magmanism.

稀土元素、微量元素、同位素等地球化学特征显示出成矿物质和成矿热液与隐爆角砾岩、霏细岩同源,成岩与成矿是同一岩浆作用不同阶段的产物。

The content of major elements, such as Fe, Mg, Ca and Al, and trace elements, such as Ti, Sr, Ni, Cr and Co, is linearly correlated to that of SiO2, which suggests that the different volcanic rocks in the basin should be the product of fractional crystallization of congenetic magmas. The parental magma may be generated by the partial melting of an enriched mantle wedge formed by the metasomatism of slab-derived fluids in an active continental margin tectonic setting.

FeO、MgO、CaO、Al2O3、TiO2等主元素和Sr、Ni、Cr、Co等微量元素的含量与SiO2含量呈明显的线性相关关系,表明该区火山岩可能是同源岩浆分异的产物,岩石形成於活动大陆边缘的构造环境,并由遭受消减板块流体交代的富集地幔楔部分熔融而形成。

The distribution characteristic of igneous rocks is similar to the magmatic activity in Cordilleran orogen, it is caused by variance of dip angle of subduction slab from 10~20° in Ca.

这种火成岩随时间的带状迁移特征与北美西部科迪勒拉造山带火成活动特征相似,它们都是俯冲板块倾角变化导致岩浆弧迁移形成的。
