H and o isotopes reveal that the metallogenic fluid may has magmatic hydrothermal in early times and the formational water in the stratum participated the maineralization during the main metallizing phase 氢、氧同位素指示成矿流体早期可能有岩浆热液，主成矿期主要是地层中的建造水参与成矿。
Carbon and oxygen isotope data show that the carbonatite layer in fozichong ledge is different from the normal marine sedimentary carbonatite , infering that its formation has relation with hot - water sedimentary activity 碳、氧同位素显示，佛子冲矿田赋矿层位中的碳酸盐岩地层与正常的海相沉积碳酸盐岩不同，其成因与热水沉积活动有关。
This study used water samples taken from fon - lin region in hualien river basin and analyzed their hydrogen and oxygen isotopes to investigate the possible sources and evolution processes of groundwater and river water flow 摘要本研究利用氢、氧同位素针对花莲溪上游凤林开发区地下水及地表水水文特性进行分析，判断该区域地下水的补注源及地表与地下水间的相互关系。
All records show the characteristics of high precipitation and large swing before 1100aad , but the characteristics of low precipitation and small swing after 1100aad . during the medieval warm period there is a very dry period 相同时段氧同位素与纹层厚度、灰度对比表明，过去2000多年主要是暖湿、干冷的气候组合方式，但在气候转型期温度、降水并没有完全表现同步变化，体现干暖、冷湿组合。
Conspicuously heavier hydrogen and oxygen isotopic compositions in maolouchi river basin after quake suggested that the water source of the rivulet mainly drained from surface runoff subjected to evaporation or the interflow composed with heavier isotopes 猫罗溪流域在地脓后其氢、氧同位素组成明显变重，此意指流至河川之水源可能改变为遭受蒸发作用之地表迳流，或以具较重同位素组成之中间流为主。
The most direct embodiment is the fluctuant images of grain - size parameters brought about by the bounce of grain - size eigenvalues . in order to discuss dune sedimentary and the cause of its evolvement , in this paper we also contrast every oxygen isotope phase 为进一步探讨砂丘沉积及其演变的原因，本文还将米浪沟湾地层剖面150ka以来不同时段样品的mz和sc d的平均值与相同时期氧同位素诸阶段进行了对比。
The composition and physicochemical condition of ore - forming fluids were determined by the analysis of chemical composition , 6 d , 18o and physical chemistry parameters of fluid inclusions in quartz veins , which are closely related to gold mineralization in gaize area 通过对石英矿物中的流体包裹体特征、成分、流体水的氢、氧同位素及其物理化学参数的分析与测定，论证了成矿流体的成分及物理化学条件。
Among them the x - ray diffraction analysis is mainly used to confirm clay mineral assemblages and their crystallinity ; chemical analysis and electronic microscope are used to study the source , the genesis and the evolvement process of clay minerals ; radioactive isotopes analysis can make up the relationship between the time and space which is based on the climate index and the chronology ; hydrogen and oxygen isotopes also provide important evidence for reconstructing paleoclimate 其中， x射线衍射分析主要用来确定黏土矿物组合及其含量以及某些黏土矿物的结晶度化学分析电镜分析主要用于黏土矿物的来源成因演变过程的研究放射性同位素的研究使气候指标和年代学建立起时间和空间上的联系而氢氧同位素分析亦能对古气候重建提供重要佐证。
By studying the ancient barrier lake sediments , this paper mainly probes into the ancient climate evolution rule of more scale and less from twenty - two thousand to ten thousand years before present , diexi , minjiang river . moreover , influences to lower reaches of minjiang river is simply discussed because of die out of the ancient barrier . the using correlative theories in this thesis are mc chronology , sedimentology , isotope geology , environmental geology , geomorphology 本论文运用~ ( 14 ) c年代学、沉积学、同位素地质学、地貌学等学科的有关理论，通过对岷江叠溪古堰塞湖湖相沉积物的研究，采用沉积物碳酸盐碳氧同位素等多环境代用指标，研究岷江叠溪地区距今约22千年10千年古气候演化规律，讨论了古堰塞湖形成演化过程与地质环境的相关性。
Little change in hydrogen and oxygen isotopic composition of rivulet before and after 921 earthquake in paikangchi and nankangchi river basin implied that the earthquake stress might just force the groundwater stored in soil or strata to flow out but did not change the water sources of the two basins 因其氢、氧同位素组成在921地脓前、后并未发生变化，因此北港溪和南港溪流域在地震之后所显示的异常水源，可能是地震的应力迫使原涵蓄于土壤或地层中之地下水流溢出，而并未改变其原集水型态。
