By thorough analysis and systemic comparison of the typical deposits and magamtic plutons, especially geochemistry of different metallogenetic granites, the source formation mechanism of granitic magma, as well as including composition and character of ore-forming fluids, the author re-recognized Yanshanian magmatic activity, ore-forming fluid action and mineralization process in Southern Hunan Province, and established the conceptual model of the magmatic intrusive contact structural system.

本文通过深入剖析和系统对比矿集区内不同成矿花岗岩体的地球化学特征、岩浆物质来源、形成机制及典型矿床的成矿地质特征，重新认识了湘南钨锡多金属矿集区燕山期花岗质岩浆活动、流体作用与成矿过程，建立了岩浆侵入接触构造体系概念模型，在以下几个方面取得了一些重要进展：1。

Based on the above studies and integrated with aerial radioactivity data, the authors identified and mapped such spectral features of main ore-forming factors of uranium deposits as ore-controlling faults, hydrothermal alterations and plutons, and evaluated geological application potentials of CBERS-02B remote sensing imagery in the Taoshan granite-type uranium deposit.

在此基础上，以江西桃山花岗岩型铀矿田为试验区，结合航空放射性数据，开展了基于02B星遥感数据的控矿断裂带、热液蚀变带及主要成矿岩体等铀成矿要素的光谱特征识别与提取，并对该数据的地学应用潜力进行了评价。

The results show that the formation-ages of granitic plutons in the southern side of the Mayin'ebo fault in the researched area are (334.1±9.5) Ma,(300±9) Ma and (280±12) Ma with the initial 87Sr/86Sr ratios of 0.70433, 0.70435 and 0.70384, respectively, and that they were generated at different stages of middle-late Variscan Movement.

选取新疆东准噶尔北部青格里河下游一带鸟图布拉克、阿热勒托别和哈旦逊岩体等具一定规模的3个代表性岩体，通过全岩Rb-Sr等时线同位素定年，确定了研究区内玛音鄂博断裂南侧花岗岩类的形成时代分别为(334.1±9.5)Ma、(300±9)Ma和(280±12)Ma，其初始87Sr/86Sr比值分别为0.70433、0.70435和

The study on petrology, geochemistry and isotope geology indicates that there are the common resource and tectonic setting for the Kangbutiebao formation with metamorphic volcanic rocks and the granite plutons related to the main iron deposits.They are different facies from magma evolvement in late Silurian-early Devonian.

岩石学、岩石地球化学及同位素研究表明，康布铁堡组变质火山岩、与主要铁矿床有关的花岗岩具有同源、同构造环境特征，是晚志留世-早泥盆世岩浆演化的不同相。

The Middle Jurassic Qitianling granite, the main intrusive body of Qitianling pluton, is studied in this paper.

本文研究讨论了骑田岭岩体的主体，即中侏罗世骑田岭序列花岗岩。

For example, in Huizhize pluton, the DS mechanism produced only about 20% space for the present volume of the pluton, the regional TE contributed 19～32% space and MS, including stoping and material transfer processes, yielded another 38% space.

例如，在秦岭造山带核部最大的灰池子花岗岩体的定位中，主动膨胀机制开辟了20％的空间；区域构造扩展提供了19～32％的空间，岩浆侵吞机制提供了37％的空间。
