花岗岩

Our stuc1 indicates that the majority of the granites in Naniclan-Hechi metallogenetic belt belong to POG, while the later stage alaskite belongs to RRG+CEUC. The granites were formed at the stage of structure transformation from postorogenic phase to intraplate setting. But the major structural environment is steady regional extension. The formation age for the granites represents the time of this transformation, and this translation environment is favored for large-scale metallogenesis.

研究表明，区内燕山晚期花岗岩主体属后造山花岗岩类，最晚期的白岗岩为RRG+CEUG型，带内岩浆岩形成于后造山向板内环境的转化阶段，主体构造环境则为较稳定的区域拉张，岩体侵位时代代表了区内构造环境的转折时期，这种区域构造体制的转换是大规模成矿的有利动力学条件。

Being rich in potassium, alkali and calcium, this belt is a series of potassic and alkalic granitoids and belongs to A-type granites. However, this kind of A-type granitoids was not formed at the end of orogeny.

岩石地球化学研究显示，该岩带的各种岩石类型都具有富钾、富碱和富钙的特点，属于钾质碱性花岗岩类，可归属为A型花岗岩类。

In addition, the features of elemental geochemistry of all samples suggest that (1) the EarlyTriassic andesitic rocks, characterized by characteristic natures of island arc volcanics, likely erupted in the subduction setting; that (2) the generation of LateTriassic rhyolites with an affinity of Alike granite and synchronously main body granites in the Lincang batholith displaying similar geochemical features, is closely related with the postcollision or latecollision setting; that (3) although the LateTriassic basic rocks partly show island arc volcanics such as highAl contents and NbTa depletion, some of them possessing highMg contents and mostly having traceelement ratios similar to intraplate basalt, which indicates that they erupted in the postcollision rift environment.

元素地球化学特征表明，早三叠世火山岩具有典型的岛弧火山岩的特征，暗示其很可能形成于俯冲的构造环境；中三叠世晚期的流纹岩与临沧花岗岩基主体具有非常相似的地球化学特征，结合其流纹岩具有A型花岗岩属性，表明该区中三叠世火成岩形成于碰撞后的构造背景；而晚三叠世基性火山岩虽然在地球化学特征上显示出与岛弧火山岩相似的高铝和NbTa的亏损，但其中部分火山岩具有高镁和板内玄武岩的微量元素比值特征，说明这些火山岩可能形成于碰撞后裂谷环境。

In fact, the NCC was dominated in the late Palaeoproterozoic by an extensional-tectonic regime, associated with the development of an aulacogen system, anorogenic magmatism (rapakivi granites, anorthosites, gabbros, granites and pegmatites), with the emplacement of large-scale mafic dyke swarms and with the uplift of the early metamorphic basement or the tectonothermal events of the retrogressive metamorphism.

事实上，在古元古代末期华北克拉通以伸展-裂解构造为主，表现为拗拉谷系发育、非造山岩浆活动(环斑花岗岩、斜长岩、辉长岩、花岗岩类及伟晶岩脉等)、大规模基性岩墙群侵位以及早期变质基底隆升或退变质构造热事件等。

According to the research of the genetic texture of zircons and SHRIMP dating in the Caledonian banded - augen granitin Yunkai area and the Indosinian charnokite in southeast Guangxi,It is discoved that the ages of later Mesoproterzoic Sibao orogeny event concentrates between 1100 and 950Ma. It provides the important evidenve for the convergent and collision of Rodinan supercontinent in South China and the south extending of Jiangshan-shaoxin collision belt in later Mesoproterzoic.

云开地区加里东期条带-眼球状花岗岩，以及桂东南印支期紫苏花岗岩中锆石的成因结构和离子探针定年研究发现，中元古末四堡造山作用事件年龄集中分布于950-1100Ma，为华南中元古末罗迪尼亚超大陆聚合碰撞造山和江绍带的南延提供了重要证据。

The same set of ductile-rheologic shear deformational augen granite samples in the Yunkai uplifted area are measured by whole-rock Sm-Nd, Rb-Sr isotopic dating system method, obtaining respectively 1414±68Ma for Sm-Nd isochron age and 490±36Ma for Rb-Sr isochron age. These ages are respectively interpreted as the time of the granitic rock formation and the time of the tectono-thermal event of ductile-rheologic shear partial melting in Caledonian, indicating that the orogeny not only took place in Caledonian, but also the more important tectono-magmatic orogeny in the late Mesoproterozic Era and can be compared with the time of global Grenville orogeny.

对云开核部韧性-流变剪切变形眼球状花岗岩石样品进行了全岩Sm-Nd、Rb-Sr同位素年龄测定，获得1414±68Ma的Sm-Nd等时线和490±36Ma的Rb-Sr等时线年龄，它们分别代表这套花岗岩的形成时代和加里东期韧性-流变剪切部分熔融构造热事件发生时间，表明云开地区不仅在加里东期发生造山运动，而且在中元古晚期发生了更为重要的构造—岩浆造山运动，其时代与全球性的格林威尔造山运动时间可以对比。

Huangling granite batholith, along with Hannan and Liyuzhai granite batholith, constructs a low-K granite belt in the northern periphery of Yangtze Platform.

黄陵花岗岩基位于扬子地台北缘，它连同汉南和鲤鱼寨岩基一起构成扬子地台北缘的低钾花岗岩等，形成于晋宁晚期扬子地台北侧的&秦岭洋&壳向南俯冲导致的大陆边缘造山运动过程中。

Combine with the "Post-collisional" geochemical characteristics and the participation of mantle-derived composition;the emplacement events of granites maybe represent a transition from collision to orogenic collapse,and the magma maybe derives from the breakoff or delamination processes,then ascend to the upper crust along the strike-slip or transtensional fault.

结合花岗岩&后碰撞&的地球化学特征及岩浆形成过程中幔源物质、热的参与等认为这些花岗岩的形成应代表了造山带由碰撞造山向造山带垮塌过渡的早期阶段，岩浆的形成可能由一些深部过程如拆沉、板片断离等引起，并沿这一时期中浅部地壳的走滑或者走滑伸展构造侵位。

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。
