In this paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.

本文重点以老厂矿田中的接触带锡铜矿床和脉状矿床为研究对象，采用化学分析、ICP-MS、X射线粉晶衍射分析、电子探针等测试手段，对本区与成矿相关的基性-超基性火山岩、花岗岩、夕卡岩、电气石-石榴石等进行了系统的地质地球化学研究，研究表明：个旧矿区中三叠纪个旧组地层中的火山岩为钙碱性玄武岩-拉斑玄武岩系列，岩石为辉石-角闪石-长石-绿泥石-金云母组合；本区的花岗岩为过铝质花岗岩，主要与燕山期碰撞造山作用有关，锡多金属成矿与形成时代最晚、分异较好的花岗岩关系密切；本区夕卡岩中的有用共生组份随着夕卡岩类型及其矿物组合的不同具有明显的分带性。

During the ductile deformation, the accompanying fluid interacted intensively with the mylonite series rocks, resulting in sericitization of plagioclases, chloritization of dark minerals and cxtcnsivc carbonatization.

中文摘要：夹皮沟金矿北西向剪切带存在着长英质和镁铁质两类糜棱岩系列岩石，韧性变形中伴随的大量流体与糜棱岩之间发生了强烈的水岩反应：斜长石绢云母化和钠化。

Non-metallic minerals are mainly limestone, dolomite, quartz sandstone, sillimanite, fire-resistant clay, broken mica, talc, serpentine, quartz, feldspar, rock wool with diabase, with finishes of granite, marble, heavy Spar, and so on.

非金属矿产主要有石灰岩、白云岩、石英砂岩、硅线石、耐火粘土、碎云母、滑石、蛇纹石、石英、长石、岩棉用辉绿岩、饰面用花岗岩、大理岩、重晶石等。

Meanwhile, the volcaniclastic rocks were modificated by the thermal fluid activity, for example, sericitization of plagioclase, chloritization of volcanic detritus in andesitic detris tuff; in the tufaceous mud, the thermal fluid activity accelerates "maturating" of the organic carbon by heating; and the trace elements show an anomaly in the wall rocks.

同时，受热流体活动的影响，热流体对火山碎屑岩具有一定改造作用，如在安山质岩屑凝灰岩中，斜长石绢云母化、火山岩岩屑绿泥石化明显；在凝灰质泥岩中，热流体对围岩中有机碳具有明显的&催熟&加热作用，微量元素则出现异常现象。

The time sequence of the Permian LIP development is as follows: Wajilitag layered rock mass→brecciated mica-olivine pyroxenite pipe→ basalt of Kupukuciman formation(278-292 Ma)→basalt of Kaipaicileike formation (272-288 Ma)→diabase and ultrabasic dikes→ syenite(277 Ma).

大火成岩省发育具有如下的时间序列：瓦吉里塔格地区的层状岩体→隐爆角砾云母橄辉岩岩筒→库普库兹曼组玄武岩(278×10^6~292×10^6a)→开派兹雷克组玄武岩(272×10^6~288×10^6a)→辉绿岩脉、超基性岩脉→正长岩(277×10^6a)。

According to petrographic facies test, gravel sample mainly consists of quartz, albite, dolomite, and minor biotite; and sand sample is mainly made up of quartz and albite. As an important ASR active mineral, chalcedonite exists in fractures of dolomite and in matrix of cherty limestone. In rapid mortar bar test, expansion of sand, small gravel and middle gravel at 14 day are less than 0.1%, but keep increasing in long term.

岩相法检测显示卵石样品主要由石英、钠长石及白云石和少量云母类矿物组成，砂样品主要由石英、钠长石等矿物组成，重要的碱活性物质玉髓主要出现在白云岩裂隙和硅质灰岩的基质中；&砂浆棒快速法&检测结果显示砂、小石、中石样品14天的膨胀率均不超过0.1％，为非碱－硅酸反应活性骨料，但卵石样品仍具有一定的碱活性，且后期膨胀率一直持续增长。

The correlation analysis demonstrates that the hydroxyl content of omphacite is correlated positively with the MgO, TFeO and Al2O3 contents, and negatively with the Na2O content of the whole rock and the Na2O and TFeO contents of omphacite, but is not related with the peak metamorphic conditions.

相关性分析显示，绿辉石的结构水含量与全岩的Mgo、TFeO、Al2O3，含量成正相关，与NaO成反相关，与绿辉石的NaO、TFeO含量成负相关，与榴辉岩的峰期变质条件无关；与其它类型榴辉岩相比，多硅白云母榴辉岩中绿辉石的结构水含量较高，平均为339ppm。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
