在矿物学方面，首次较为系统地研究了超高压变质岩中的金红石、磷灰石、绿帘石等副矿物，并通过详细的岩相学和矿物化学研究，首次在苏鲁-大别超高压变质岩中发现了一些具有特殊成分/结构的矿物或矿物组合，如在榴辉岩金红石中发现了刚玉、菱镁矿、高钛黑云母和石榴石矿物包裹体，在片麻岩中发现了Nb-Fe金红石和具有自形环带结构的高Si-Y磷灰石，在榴辉岩和片麻岩中发现了具有类似岩浆成因的自形生长环带结构的绿帘石/褐帘石，在片麻岩的脉体中发现了大量富含稀土元素REE、高场强元素HFSE(Nb、Ta、Zr、Ti)、大离子亲石元素LILE(K、Th、U、Sr、Ba)，以及挥发性组份(CO_2、F、P、S)的特殊矿物，丰富并提升了超高压变质岩的矿物学研究。2。

The studies on ore-forming geochronology and ore fluid are conducted deeply in this paper.

本文对甘肃北山地区肃北县南金山金矿床的成矿年代学和成矿流体进行了系统研究。40Ar-39Ar同位素测年结果表明，南金山金矿石中绢云母的40Ar/39Ar坪年龄为242.8±0.8Ma，相当于印支早期，略晚于南金山金矿床附近闪长岩中黑云母的40Ar/39Ar坪年龄(244.2±0.3Ma)，这表明印支早期闪长岩对南金山金矿床的形成起着重要的控制作用。

The contents of Ni, Au, Mo, W of the deep-seated xenoliths and their host basalts from eastern China are inhomogeneous. The contents of Ni, Au are highest in the mantle-derived xenoliths the contents of Mo, W are highest in the basalts and the mafic granulite, and the leptite and the granitoids, respectively.

地球深部包体中镍、金、钼、钨等成矿元素的含量是不均一的，镍和金在地幔岩包体中含量最高，铝在玄武岩及镁铁质麻粒岩包体中最高，而钨在长英质麻粒岩和花岗岩类包体中含量最高。

Mafic granulite and gabbro xenoliths are also found in the same kimberlitic pipes from the Eastern-North China platform, and suggest that multi-accretion events took place. The gabbro was formed lighly earlier with the host kimberlite. The underplating of the mafic magmas was related to the continental orogeny in the late middle-Ordovician Period.

金伯利岩中强烈变质的基性麻粒岩以及变质不彻底的粗粒辉长岩在同一岩管中共存，表明华北古老岩石圈地幔所发生的多次增生作用事件，特别是后者的变质不彻底变质作用暗示其形成时代与金伯利岩相近，这种基性岩浆的底侵作用与华北地台中奥陶世晚期的造陆抬升有关。

The difference between the lithosome shape, distribution of kimberlite and the physical natures of adjacent rock decides the size, intensity of anomaly and the reflecting degrees. The anomaly range of elements Cr、Ni 、Nb has the direct corresponding relationship with the shape of kimberlite pipe or vein.

综合物化探异常与矿体吻合较好；金伯利岩岩体形状空间分布与围岩的物性差别，决定了异常大小强弱、反映明显程度； Cr、Ni 、Nb的元素异常范围与金伯利岩管的形状有直接的对应关系。

The first type, kamafugite, is plagioclasefree, consisted of Tirich phlogopite, melilite, leucite and nephelite. They have lower contents of SiO2 and Al2O3, but have high TiO2, CaO, MgO contents and K/Na and Mg# ratio whereas the second type, potassic trachybasalt, is abundant in plagioclase and contains no phlogopite, melilite, leucite and nephelite. They have higher SiO2, Al2O3,(Na2O+K2O), and lower TiO2, CaO, MgO, and K/Na and Mg#, in comparision to the first type of rocks.

钾霞橄黄长岩是一种不含斜长石，但普遍含有高钛金云母、黄长石、白榴石、霞石的岩石，全岩化学成分具低SiO2和Al2O3，富TiO2、CaO、MgO和高K/Na、高Mg#值的特征；钾质粗面玄武岩含有大量斜长石但是缺乏高钛金云母、黄长石、白榴石和霞石，全岩化学中SiO2、Al2O3明显高于前者，而TiO2、CaO、MgO、K/Na和Mg#值要比钾霞橄黄长岩低。

Study using infrared microtechnique reveals three types of fluid inclusions in rutile:Ⅰ-type aqueous inclusions,Ⅱ-type CO_2-H_2O inclusions and Ⅲ-type CH_4 inclusions. Primary and pseudosecondary type Ⅰ inclusions, as well as Ⅱ-type fluid inclusions, having a range of pressure between 0.6 and 1.3 GPa, were trapped during the amphibolite-facies retrogression stageof eclogites, suggesting that fluids related to rutile mineralization originated from water released during retrograded metamorphism of eclogites.

利用红外显微镜对金红石进行的流体包裹体研究表明，金红石中主要存在三类流体包裹体，即Ⅰ型H2O溶液包裹体、Ⅱ型CO2-H2O包裹体和Ⅲ型CH4包裹体，其中I型原生和假次生流体包裹体和Ⅱ型流体包裹体反映出的压力范围为0.6～1.3 GPa，与榴辉岩角闪岩相退变质作用的压力相当，说明与这类金红石形成有关的变质流体源于榴辉岩退变质作用所释放的水。

At western segment of Altyn Tagh tectonic belt, The eclogites and khondalite series were recognized in Altyn Group (Early Proterozoic?) Which had been thought prviously that it consists of high greenschist facies and lower amphibolitic facies metamorphic rocks. They crop out at the northern slope and southern slope of Altyn Tagh Mountains respectively.

在阿尔金构造带西段，在原认为主要由高绿片岩相—低角闪岩相的阿尔金群中，发现有榴辉岩及麻粒岩相的孔兹岩系，它们分别分布在阿尔金山的北坡和南坡。

The biometallogenesis system of Jinya gold deposits consists of the following procedure: pre-concentration of gold and metallogenic matter in living organisms in Luodian-Danchi rift depositional basin; solution, absorption and concentration of metallogenic matter in organic matter and organic thermal fluid generated from organisms during lithogenesis; migration of gold and metallogenic matter in organic fluid from basin to Lingyun underwater carbonate platform and concentration at its boundary convex (palaeo-blind-mountain) during basin compaction ; metallization due to depth thermal fluid making organic fluid thermal degradation and forming new fluid which riches in gold and sulfur, and the fluid migrating upward and depositing in upside ore-controlling structures because of absorptions by organic carbon and atc.

通过研究金牙金矿作用的生物成矿系统内容为：在早、中三叠世罗甸—丹池裂谷盆地接受沉积时，生物对金等成矿物质就存在预富集作用；在成岩过程中，生物转化为有机质及有机热流体，对生物及沉积物中的金等成矿物质存在溶解、萃取、富集作用；在盆地压实成岩作用中，盆地中有机热流体向凌云水下碳酸盐台地运移，并在台地边缘外凸部位集中，此过程流体携带大量成矿物质，对金等成矿物质存在迁移集中作用；深部热流上侵使有机流体发生降解和释放金的热作用、形成高含金的有机热液，含金热液上移在构造通道中沉积并被有机碳再次吸附，最终形成金矿床，对金存在成矿作用。

The dark dikes associated with mineralization in the Jinchanggouliang mine area,are mostly fine diorite-quartz diorites and diorite porphyrite-dacite porphyries.

金厂沟梁金矿区中与成矿伴生的暗色脉岩主要是细晶闪长岩石英闪长岩、闪长玢岩英安斑岩类。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
