Metallogenic conditions are analyzed from the magmatism of REE bearing syenite,hydrothermal activity and fracture activity.

从富含稀土的正长岩岩浆活动、浅成热液作用和断裂构造分析了矿床成矿条件。

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。

But detail geochemical study indicates (Wu et al., 2002)that those rocks have low Sr〓(0.706), high ε〓(-0.5～-1.9), young age of Nd model age (970-1090Ma) and syngenesis with surrounding I-type granites. The rock originated from partial melting of source igneous rock and belongs to I type granites. The occurrence of high alumina minerals is related to the intense interaction of magma and liquid during the late period of magma evolution, and tetrad REE patterns are formed.

但详细的地球化学研究表明(Wu et al。，2002)，岩体具有低的Sr〓(0.706)、高ε〓(-0.5～-1.9)、年轻的Nd模式年龄(970-1090Ma)及与周围Ⅰ型花岗岩的共生关系，认为岩体是火成岩源岩物质部分熔融的产物，属于Ⅰ型花岗岩，高铝矿物的出现与岩浆演化晚期强烈的岩浆—流体相互作用有关，并形成特征的稀土元素四分组效应。

Petrographic and REE and trace element geochemical studies of these rocks and Nd isotope analysis of amphibolite indicate that the protoliths of the Mengjiatun Formation complex are sandstone, mud-rich sandstone and island arc tholeiite.

对这些岩石的岩相学，稀土元素，微量元素地球化学的研究和斜长角闪岩Nd同位素的初步分析，表明孟家屯岩组的原岩建造为一套砂岩，富泥质砂岩和岛弧拉斑玄武岩组合。

Two REE distributed pattern, LREE-depleted and flat, which display a specific character of typical mid-ocean ridge tholeiite, indicate that primary magma may be derived from near primary or a typical large ion lithophile element-depleted mantle.

岩石稀土元素配分模式可分为LREE平坦型和LREE亏损型两类，指示了其原始岩浆起源于近原始或典型的大离子元素亏损型的地幔，为典型的大洋中脊拉斑玄武岩的特征。

This article elabo rates the theory and method for realizing parametrization of the original design .In the DCL interface,graph data videotex has been realized by using standard th ree-dimension object model,stamp parameter has also been introduced.

本研究针对AutoCAD平台上的三维实体功能以及PDB管理功能的DCL技术，提出了利用标准结构的主要特征参数实现原型图的参数化方法。

Important natural geological analogues are volcanic glass and meteoric glass(anal-ogues of solidified mass), clay minerals (natural analogues of backfill material), iron meteorite and copper deposits (natural analogues of waste containers), natural nuclear reactors, uranium deposits, iron deposits containing Th and REE and contact zones between igneous rocks and other rocks (natural geochemical analogues of HLW repository).

目前已有的地质类比研究对象主要有火山玻璃，陨石玻璃，粘土矿物，铁陨石，铜矿床，铀矿床，含含Th和REE的铁矿床，天然核反应堆和火成岩接触带等。
