查询词典 granite paper

Combined with related rare earth element and trace element geochemistry of Huangshaping granites and ore-bearing skarn, it is concluded in this paper that the age of 154 Ma should represent the metallogenic epoch of the deposit, and that there existed a close relationship between the ore-forming process of the deposit and the granite porphyry, which were both formed during the peak stage of Early Yanshanian large-scale rock-forming and ore-forming activities in South China.

结合黄沙坪岩体及含矿硅卡岩型矿体的稀土及微量元素地球化学特征，得出以下认识：该矿床的成矿年龄在154Ma左右；成矿作用与花岗斑岩关系密切，它们都是华南燕山早期大规模成岩成矿作用高峰期的产物。

According to the heterogeneous migmatite and granite of South and North Dabie Blocks, and the formula △h=h which was inferred in this paper, the melting of metamorphio rock might make NB uplift about 4. 4km, but SB only about 1. 9km. Therefore, the difference of melting degree of metamorphic rocks of NB and SB led to the volume different, and this could be one of the reasons of different uplift of NB and SB.

根据南、北大别地块混合岩、花岗岩分布不均匀的特点和本文推导的公式Δh=h(〓-1)估算表明，变质岩的熔融可使北大别地块隆升幅度达4.4km，而南大别隆升幅度仅为1.9km，因此，南、北大别变质岩熔融程度差异所引起体积变化的不同，可能是南、北大别地块差异隆升的原因之一。

In this paper, the geochemical characteristics of granite in Jiangjunzhai tungsten deposit and the Re-Os isotopic dating of molybdenite from quartz-wolframite veins were studied and carried out, in order to elucidate the timing of mineralization and reveal the time limites and geodynamic setting of large-scale metallogeny in Southeast Hunan.

文章研究了白云仙矿田将军寨钨矿花岗岩的地球化学特征，并进行石英脉型黑钨矿石中辉钼矿的铼－锇同位素定年，以精确厘定将军寨钨矿的形成时间，揭示湘东南地区钨、锡等有色金属成矿的时限及其地球动力学背景。

The age of alkali- granite is 320 Ma. Therefore, the paper proposesthat Altay orogenesis ended before the early stage of middle Carboniferousperiod.

碱性花岗岩形成年龄为320Ma，阿尔泰造山作用在中石炭早期之前即已结束。

In this paper the suit of granodiorite is prelimnarily proved to be remelt type granite in which the major rock-forming substances are derived from the crust and a few from the mantle by study on petrology, genetic mineralogy, geochemistry, trace elements, rare earth elments and isotopes combining with the re gional geological evolution and geological chronology.

此次工作，通过进一步对该套岩体的岩石学、矿物学、地球化学、微量元素、稀土元素和同位素等方面研究，并考虑了区域地质演化和地质时代等因素，基本上证明其并非幔源分异型花岗岩，也不是典型I或S型花岗岩，而是一种以地壳物质为主、地幔物质为辅的混源重熔型花岗岩。

The paper alse proposes that" there occurs anorogenic alkali-granite conter-overstep distribution in Altay orogenic belt" with was resulted from conter-moving of tensional stress, and the bundary of conter-overstep distribution could be used as a sign to determin suture belt of ancient plates.

本文同时还提出了&阿尔泰造山带存在有非造山富碱花岗岩反向超伏分布&的新观点，产生非造山富碱花岗岩反向超伏分布的机制是地幔上穹引起的张性应力逆向推移，并认为非造山富碱花岗岩反向超伏的起始界线可做为确定古板块缝合线的重要依据之一。

In this paper, the petrographical characteristics and mechanical properties of Zhejiang granite are studied to elucidate the relationships between them.

对浙江省花岗岩的岩相学特征及力学性质进行了研究以确定它们之间的关系。

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.

根据区域构造演化分析，并结合本文及他人高精度同位素年龄，我们对延边花岗岩形成的大地构造环境有了新的认识：1在华北地台北缘并不存在所谓的加里东花岗岩带，因此，建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的；2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带，表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪，即不存在传统观点所认为的加里东期或海西期活动陆缘；3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞，致使地壳和岩石圈增厚，导致加厚岩石圈发生拆沉作用，使得软流圈上涌，加热地壳使之熔融形成岩浆，但玄武质岩浆少量喷出地表，大部分底侵于地壳底部，形成下地壳高密度的玄武质底侵层，玄武质岩浆底侵的热能引起中下地壳广泛部分熔融，形成大面积分布的晚二叠世—早三叠世花岗岩。
