Sn with the content of 0.004% in the lithosphere is almost in presence of cassiterite and little in presence of Sn-contained sulfide. Since 1980s, the anticancer active study on organic complex compounds has attracted considerable attentions, it becomes another hot issue after the study on Pt. When time up to the year 1989, the anticancer active measurement of more than 2000 kinds of Sn-contained complex compounds have been carried out by Cancer Academy, U.S, with the results showing half of these Sn-contained complex compounds posses antileucocythemia(P388) activity. Thereafter, Sn-contained complex compounds synthesized by hydrothermal reaction also become a hot issue people focus on.
Sn在地壳中的含量为0.004%,几乎都以锡石的形式存在,此外还有极少量的Sn的硫化物。20世纪80年代以来,人们对Sn有机配合物抗癌活性的研究产生了浓厚兴趣,成为继顺铂之后又一活跃的研究热点,到1989年,美国国家癌症研究所对2000多种Sn的配合物进行了抗癌活性测定,结果表明,50%的配合物具有抗P388白血病活性,故水热溶剂热合成锡的配合物也成为人们的研究热点。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.
矿石中天然固有的杂质严重影响其后来的质量。矿石的形成是地质变迁的结果,包括地壳运动,火山爆发,沉积作用,冰河作用和风化等等,在这些作用下,生成了火成岩,火山杂岩,水成岩和沉积岩等,一些矿石是由于这些作用共同形成的,这就是自然界中没有纯净矿石的原因。由于这些原因的存在,需要用分离技术和器械,也就是矿石加工设备对矿石进行的分割,迄今为止这些矿石加工设备已经不能够满足冶金工业的需要,科学家们力图用激光把冶金工业提高到一个新的水平。

Corrosion process of water flow could have great impact on dissolvable rock area in several decades.
岩石风化作用既是地壳固体物质形态转变的重要途径,也是产生块体运动灾害的必要前提条件,其类型和强度受区域气温及降雨条件的控制;水的侵蚀作用的区域性规律受地貌成因和气候条件的制约,它对陆地环境的最大冲击是对海洋、湖泊及水库岸滩带的侵蚀和改造;流水的溶蚀作用可在几十年内对可溶岩类地区产生影响。

Baishishan the top of the dolomite cap rock was formed 10 billion years ago the marine environment; crustal movement to make this piece of dolomitic marble produced more than two sets of vertical joints, in the long years of millions of years later, the weathering so that the vertical cracks expanding into a arrhizus rock column of Qifeng Li; Moreover, these columns, such as Lin Qifeng Li has just standing on a solid granite base, making them also another insurance Fenglin odd geological movement continues to be able to has been retained.
白石山上部的白云岩盖层形成于10亿年前的海洋环境;地壳运动使这块白云质大理岩产生了两组以上的垂直节理,在后来亿万年漫长的岁月里,风化作用使垂直裂隙不断扩大,岩层变成了根根柱立的奇峰;而且,这些柱立如林的奇峰又正好伫立在稳固的花岗岩基座上,使得这些又奇又险的峰林在不断的地质运动中能够被保留下来。

These results suggest that the diagenesis material of the Xiangshan volcanic intrusive complex was derived from crustal sources. The sources either had relatively lower maturity or had more juvenile mantle-derived igneous rocks than the exposed basement metamorphic rocks. Involvement of a small amount mantle-derived magma during the formation of the Xiangshan volcanic-intrusive complex was also possible. The diorite enclave, sub-quartzmonzonitic porphyry and lamprophyre were probably different mixing products between mantle and crust materals.
上述同位素示踪结果充分证实:相山火山-侵入杂岩的成岩物质主要为壳源,但与该区出露的基底变质岩相比,其物源区的成熟度相对较低或含有一定量的火成物质,并且不排除在其成岩过程中少量地幔物质的介入;闪长质包体、次石英二长斑岩及煌斑岩的成岩物质均含有一定量的地幔组分,可能为壳-幔混合作用的产物,只是受地壳物质混染的程度不同而已。

The metal elements of the volcanic-hosted massive sulfide deposit have two sources, the copper and zinc are derived from rhyolitic magmas whereas the lead are probably related to old sediments overlying the rhyolites.(4) It is suggested here that the volcanic rocks hosting massive sulfide deposit in the north Qilian orogen, which are previously considered as a bimodal suite of Neo-proterozoic to middle Cambrian age in a continental rift, are virtually related to subduction magmatism in Ordovician age, and there might have no continental rift magmatism of Neo-proterozoic to middle Cambrian in the north Qilian.
Th/Ta比高(5.0~11.7),εNd为较大的负值(-2.6~-8.4),流纹岩的形成可能是两个端元组分混合的过程、或是上地壳混染的结果,形成在活动陆缘环境;(3)北祁连块状硫化物矿床成矿金属物质具有两种来源,Cu、Zn等来源于流纹岩,而Pb的来源可能与古老沉积物有关;(4)本文认为,前人厘定的北祁连新元古代-中寒武纪赋存块状硫化物矿床的大陆裂谷双峰式火山岩应是与俯冲作用有关的奥陶纪火山岩,说明北祁连可能不存在新元古代-中寒武纪的大陆裂谷活动。

On the basis of previous research and the authors' field investigations,it is thought that the complex geological structures,strong crust movements and rivers erosions,frequent earthquakes,abundant loose deposits,favorable geomorphology,well-developed modern glaciers and plentiful precipitation are the principal causes of triggering frequent mudflows in the study area.
根据前人的成果以及作者的实地调查,认为复杂的地质构造、强烈的地壳运动和河流切割、频繁的地震、丰富的松散堆积物、有利的地形地貌、现代冰川以及丰沛的降雨是研究区泥石流灾害频繁发生的主要原因。
