Based on the Re-Os isochron method of molybdenites, this paper measured directly the ore-forming age from skarn ore in the Huangshaping deposit, and got a Re-Os age of (153.8±4.8)Ma, which is in accordance with the previous K-Ar age of 153~157 Ma obtained from phlogopite in the ore-bearing skarn of the deposit.

文章采用高精度的辉钼矿Re-Os等时线定年法，直接测得硅卡岩型矿体的矿化年龄为(153.8±4.8)Ma，与前人获得的含矿硅卡岩中金云母的K-Ar年龄(153~157Ma)一致。

The results show that the quaternary ammonium cations C12 TA(superscript + and C14 TA(superscript +) with short alkyl chain only react with the hydration cation in the interlamerllar space of hydrobiotite, while those with long chain C16 TA(superscript + and C18 TA(superscript +) first react with the hydration cation, then with the kalium cation in phlogopite interlayer.

结果表明：较短链长的季铵盐阳离子C12TA(上标+， C14TA只与水黑云母蛭石晶层中的水合阳离子发生反应；而长链季铵盐阳离子C16TA(上标+， C18TA先同蛭石晶层的水合阳离子交换反应，再与云母晶层中的钾离子发生交换反应。

The plateau ages of three phlogopite samples from the Bailashui ore district are (150.6±1.0) Ma,(157.3±1.0) Ma and (154.7±1.1) Ma, respectively; and the plateau age of hydrothermal hornblende from the same mining district is (156.9±1.1) Ma.

研究结果表明，白腊水矿区3个金云母样品的40Ar/39Ar坪年龄分别为（150.6±1.0）Ma、（157.3±1.0）Ma和（154.7±1.1）Ma；热液成因角闪石的坪年龄为（156.9±11）Ma。

The transition of source region from lithospheric mantle to asthenosphere indicates the thinning of lithospheric mantle and upwelling of asthenosphere caused by large scale strikeslip fault, which is the major controlling factor for decomposition melting of phlogopite in the metasomatized lithospheric mantle to generate the typeI ultrapotassic magmatism.

岩浆源区从岩石圈地幔向软流圈演变，暗示大型走滑断裂引起的岩石圈地幔减薄和软流圈上涌是导致交代岩石圈地幔金云母分解熔融产生区内I型超钾质岩浆的主控因素。

Through analysis of the experimental data about ultrapotassic rocks, typeI ultrapotassic rocks came from the source region of phlogopite harzburgite that had undergone metasomatism of fluid enriched in silica and potassium; while the source region of typeⅢ potassicultrapotassic volcanics is carbonated peridotite mantle bearing potassic amphibole.

综合超钾质岩石的实验资料，可知区内I型超钾质岩的源区以富硅、富钾流体交代形成的金云母方辉橄榄岩为主；Ⅲ型钾质超钾质岩浆源区则以斜辉橄榄岩地幔为主。

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。

The rock mass consists of fresh sericite quartz phyllite or fresh leptynite.

岩体为新鲜绢云母石英千枚岩或新鲜变粒岩。

Titanium white for the hard rock with chlorite sericite phyllite.

岩性为含白钛矿硬绿泥石绢云母千枚岩。

Fault rocks, microstructures and homogeneous temperature (concentrated around 160℃) of fluid inclusions in the quartz veins shows that the fault belt mainly underwent shallow brittle deformation and the highest-grade dynamic metamorphic rock is mylonitized sericite phyllite.

显微构造、断层岩与石英脉流体包裹体均一温度(集中在160℃附近)均显示，断裂带以浅层脆性变形为主，最深动力变质岩仅为糜棱岩化绢云母千枚岩。

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。
