斑岩的

The andesite lava (114Ma) and quartz porphyry (94Ma) are of Early Cretaceous age.

安山岩（114Ma）和石英斑岩（94Ma）则是早白垩世火山活动的结果。

In Late Jurassic period (159-135Ma), when the orientation of maximum principal compressive stress was NW direction, the Wuzhangshan granite intruded to upward, accompanied the formation of NW trending Sanrenchang and Huangshuian breccia pipe belts; In the Early Cretaceous period (135-120Ma), when the orientation of maximum principal compressive stress was NNW trending, the second stage of Huashan granite intruded to upward, accompanied the formation of NW trending Qiyugou breccia pipe belts; In 120-105 Ma, when the orientation of maximum principal compressive stress changed to NE direction, the gold-bearing quartz veins and gold orebodies in breccia pipes were formed along the NE trending fractures; In the Middle Cretaceous period (105-85 Ma), when the orientation of maximum principal compressive stress was NEE, the NEE trending Leimengou granite porphyry intruded to upward, accompanied the formation of NEE trending Leimengou breccia pipe belts.

在晚侏罗世(159～135Ma)，构造应力场最大压应力方向为NW向，形成了NW走向的五丈山岩体以及NW向展布三人场、黄水庵两个角砾岩带；在白垩纪早期(135～120Ma)，最大压应力为NNW向，形成了花山岩体第二期上侵，并伴有NW向的祁雨沟角砾岩带；其后(120～100Ma)，构造应力场最大压应力方向变为NE向，形成了NE向含金石英脉及角砾岩体中金矿体；最后(100～80Ma)，形成了雷门沟花岗斑岩以及NEE向展布的雷门沟-杨河沟角砾岩带(区域构造应力场的最大主压应力方向为NEE向)。

Quartz - vein type and greisen - type associated with tungsten, and porphyry - type are major types of Sn deposits, In recent few years, a new type of tin deposit- clastic altered rock type has been discovered, which made new development in tin - probing.

赣南地区是闻名于世界的钨锡矿产区，区内锡矿主要有与钨矿共生的石英脉型、云英岩型，斑岩型，隐爆层间裂隙带型等类型，近年来，又发现了锡矿新类型——破碎蚀变岩型，使本区找锡又有了新的进展。

Data of major andminor elements in magnetite, cassiterite, galena and sphalerite from oredeposits within this ore belt suggest that these ore deposits are of skarn,hydrothermal, porphyry and greisen types related to Yanshanian magmaticactivity and that iron in ores came from regional Permian marine interme-diate-basic volcanic rocks whereas partial lead and zinc from Permian geo-synclinic sediments.

矿带中各矿床的磁铁矿、锡石、方铅矿、闪锌矿的主元素和微量元素数据表明，这些矿床是属与燕山期岩浆活动有关的矽卡岩型、热液型、斑岩型和云英岩型矿床；其成矿金属组分中的铁来源于区域晚古生代海相中-基性火山岩，部分铅锌来源于区域二叠纪地槽沉积物。

The mantle-derived peridotite inclusions with protogranular texture and porphyroclastic textures;(2) the pyroxenite inclusions with cumulate texture; and (3) the granulite and gneisses with crystalloblastic textures.

辽西的深源岩石包体也有三种结构类型：①具有原生粒状结构、残碎斑结构的幔源橄榄岩类岩石包体；②具有堆晶结构的辉石岩类包体；③具有变晶结构的麻粒岩和片麻岩类岩石包体。

Petrochemistry, trace element, REE and isotope geochemistry of quartz syenite porphyry, quartz diorite porphyry, rhyolite, and biotite granite indicate that they belong to series Ⅱ granite defined by Wangliankui (l972), but they have some characteristics of series Igranite, which shows adding of recycle upper-crust materials.

岩浆岩岩石化学、微量元素、稀土元素及同位素地球化学特征表明，莲花山矿区的石英正长斑岩、石英闪长玢岩、流纹岩和黑云母花岗岩属于王联魁(1972)所划分的系列Ⅱ花岗岩(相当于Ⅰ型磁铁矿系列花岗岩)，但也具有系列Ⅰ花岗岩的某些地球化学特征，表明岩浆中有再循环上地壳物质的加入。

长石眼球构造的形成主要是由长石与石英的韧性差决定的，塑性变形首先从斑晶的周围部分开始，逐渐向斑晶发展，脆性残斑核不断减小，这与剪切带内糜棱岩化强度分带相一致。

Combined with the regional data the research indicates that (1) the Tianmenshan main body formed in the Middle Jurassic Epoch, whereas the minor body was the further differentiated and evolutive product of the main body;(2) in the Chongyi-Dayu-Shangyou ore concentrated area, the west of Gannan area, the diagenetic age and metallogenic age are basically concordant, and the mineralization concentrated during 150~155 Ma;(3) from the middle-plutonic granite intrusion to the hypabyssal granite-porphyry vein, the magmatic activities experienced only 1~5Ma, indicating there was the concentrated period of mineralization.

结合区域资料，研究表明：①天门山岩体的主体形成于中侏罗世，补体是主体进一步分异演化的产物；②在赣南西部的崇余犹矿集区内成岩与成矿的年龄基本上是协调一致的，成矿集中期为150～155 Ma；③岩浆活动由中深成相花岗岩侵入体演化到浅成相花岗斑岩脉仅相差1～5Ma，表明存在成矿集中期。

Finally, it can be concluded for the first time that there was a large time gap between diagentic process of the volcanic rocks related to the Dapingzhang VHMS deposit and the ore-forming process, then a ore-forming model of the Dapingzhang deposit can be made, that is, the deposit passed through two important stages: the ore-forming metals concentrated during formation of the Early Palaeozoic spilite-quartz keratophyre on the island-arc belt, and the mineralization caused by the Late Palaeozoic magmation.

最后，首次提出与块状硫化物矿床有关的火山岩成岩过程和成矿过程可以有较大的时间间隔。在此基础上建立了大平掌矿床的成矿模式，并认为成矿作用可能经历了两个重要阶段，即早古生代岛弧型细碧岩-石英角斑岩建造形成过程中成矿元素的初始富集和晚古生代岩浆活动最终导致成矿。

The comparison of petrology, lithofacies, petro-geochemistry and tectonic environment of the rapakivi granite both from Qinling-Kunlun and world shows that the rapakivi granite has same or consistent characteristics: rapakivi structure, sub-aluminous, high-potassic, alkali-rich magma, two-peak magma assemblage and formed in post-collision environment. However, there are some certain differences in some geochemical index, forming age of magma, and geotectonic position of outcropping.

通过秦岭－昆仑造山带中的环斑花岗岩同世界元古宙环斑花岗岩的岩石学、岩相学、岩石地球化学和构造环境等方面的对比研究发现，二者具有相同或一致的特征：具环斑结构，属准铝、高钾、富碱岩浆，具双峰式岩浆组合，形成于后碰撞环境，但其地球化学的某些指标、岩浆形成时代和出露的大地构造位置等有一定差异。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
