花岗岩

Metamorphic and tectonic domains of China.

有关花岗岩问题的一些讨论。

All of these charac-teristics are similar to those of continental crust transformation series granite in South China,implying that their parent magma may be derived from the unexposed Proterozoic metasedimentary rocks.

这些特征都相似于华南陆壳改造系列花岗岩，它们的母岩浆可能来源于

Rich in mineral resources have been found in the minezan 48 species, has been developed using 24, mainly iron, gold, silver, lead, zinc, molybdenum, fluorite, zeolite, silica, feldspar, bentonite, perlite, limestone, purple soil, silica sand, granite, strontium series, metasilicate series, the mineral series.

矿产资源丰富，已经发现的矿咱有48种，现已开发利用24种，主要铁、金、银、铅、锌钼、莹石、沸石、硅石、长石、膨润土、珍珠岩、石灰石、紫砂土、硅砂、花岗岩、锶系列，偏硅酸系列、矿泉水系列等。

Close scrutiny of the mineralogy and mechanical properties of the granite provides a good signs of metasomatic alteration in these rocks.

矿物学研究显示出花岗岩的交代蚀变特征，这可以反映在岩石的力学性质上。

The granites of syntectic typeand metamorphic-mixed metasomatic type are associated only with uranium occurrences.

变质混合交代型和同熔型花岗岩只有铀矿点或矿化点产出。

Methods Based on the analysis for the inner structural CL images of zircons, the U-Pb ages and Hf isotopes of zircons from the host granites, mafic microgranular enclaves and diorite dykes have been discussed using in situ zircon analysis of the LA-ICPMS and MC-ICPMS.

在锆石内部结构的CL图像研究基础上，用LA-ICPMS和MC-ICPMS测定锆石U-Pb年龄及Hf同位素组成，探讨寄主花岗岩、暗色闪长质包体及及围岩中闪长质脉体锆石U-Pb年代学及Hf同位素组成特征。

At the late stages of the ore_forming process, the main ore_forming fluid was NaCl_H2O. According to characteristics of the fluid inclusions, high 3He/4He ratios and the existence of lots of mafic microgranular inclusions, the authors consider that the ore_forming materials of the Longshang tin_polymetallic deposit were derived from multiple sources. The ore_forming fluids were mixed with mantle, crust and atmospheric water. Under the control of igneous and surrounding rocks, the mantle ore_forming fluids played a key role in mineralization at the early stage of the ore_forming process.

根据流体包裹体特征，结合高3He/4He比值以及在锡田花岗岩中存在大量镁铁质微粒包体，笔者认为：锡田垄上锡多金属矿床成矿物质是多来源的，成矿流体为地幔、地壳和大气水的混合产物；锡多金属来源受岩浆和围岩控制，而在成矿作用过程中尤其是成矿早阶段，地幔成矿流体可能起到了积极的甚至关键的作用。

By analysing the molasse sediment, tectonic stress field, thrust fault system and comparing them with volcanic rocks and granites in the region, it is showed that Dabie orogenic belt had a strong intracontinental orogenesis whose deep dynamic processes were controlled by subduction with delamination during late stage of Cretaceous period-late Cretaceous period.

磨拉石沉积、构造应力场、逆冲断层系统和区域火山岩、花岗岩的综合分析表明，大别造山带早白垩世晚期—晚白垩世存在一次强烈的陆内造山作用，其深部动力学过程受控于拆沉中的俯冲作用。

The age of peripheral monzonitic granite (XTM04-1) is 46.6±0.6 Ma, implying that this granite suite was formed in the ore-forming stage of Eocene.

外围二长花岗岩(XTM04-1) U-Pb SHRIMP年龄的测定值为46.6±0.6 Ma，表明其侵位于成矿时代的始新世。

Ore mineralization and alteration are mainly distributed in external contact zone of Yanshanian moyite and marble of Jining rock group, outcrop of three strip ore bodies, a lenticular, vein, cystic and so, for direct prospecting signs of iron and manganese cap.

矿体及矿化蚀变带主要分布在燕山期钾长花岗岩与集宁岩群大理岩的外接触带上，地表出露三条带状矿体，呈透镜状、脉状、囊状等，直接找矿标志为铁锰帽。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
