Carbon dioxide is a common and important component in fluid inclusions. Because carbon isotopic ratio of CO2 in fluid inclusion can provide geochemical characteristics of source rocks, many works have been conducted to measure the carbon isotopic ratio (13C/12C) of CO2. In general, carbon isotopic composition (13C/12C) of CO2 fluid inclusions are measured by mass spectroscopy. However, mass spectroscopy is a destructive analytical technique, and can not be applied to measure single inclusion. Raman spectroscopy is an efficient non-contact and non-destructive method, and has been widely employed in many research fields. In fact, due to the difference of carbon atom mass, the Femi resonance of 13CO2 is lower than that of 12CO2, so they can be identified in Raman spectrum. In principle, the carbon isotopic composition (13CO2/12CO2) in CO2 is closely related to the Raman intensity ratio between 13CO2 and 12CO2 (I + 13 /I + 12 ). Therefore, Raman spectroscopy can theoretically be utilized to measure the carbon isotopic composition (13CO2/12CO2) of CO2. However, this method is seriously hampered by the poor measurement accuracy and precision. In this study, based on the theoretical analysis, and in combination with previous Raman studies on carbon isotopic composition in CO2, a preliminary research on Raman quantitative measurement for carbon isotopic composition in CO2 was carried out. 相似文献

This paper introduces the software solution Bingo-Antidote for thermodynamic calculations at equilibrium based on iterative thermodynamic models. It describes a hybrid strategy combining the strength of Gibbs energy minimization (GEM) and inverse thermobarometry models based on the comparison between the modelled and observed mineral assemblage, modes and compositions. The overall technique relies on quantitative compositional maps acquired by electron probe micro-analyser for obtaining a mutually consistent set of observed data such as bulk rock and mineral compositions. Thus it offers the opportunity to investigate metamorphic rocks on a microscale. The scoring part Bingo integrates three statistical model quality factors for the assemblage, for the mineral modes, for the mineral compositions combined in a global evaluation criterion that quantifies how the model reproduces the observations for the investigated volume. The input parameters of GEM affecting the model quality such as pressure, temperature and eventually some components of the bulk composition (e.g. the molar amount of hydrogen, carbon or oxygen) or activity variables of fluids and gases (e.g. , , f(O2)) can be optimized by inversion in Antidote using several mapping stages followed by a direct search optimization. Examples of iterative models based on compositional maps processed with Bingo-Antidote demonstrate the utility of the program. In contrast to the qualitative interpretation of phase diagrams, the inversion maximizes the benefits of GEM and permits the derivation of statistically ‘optimal’ pressure–temperature conditions for well-equilibrated samples. In addition, Bingo-Antidote opens new avenues for petrological investigations such as the generation of chemical potential landscape maps. 相似文献

胶北地体位于华北克拉通东南缘,其太古宙-古元古代的岩石组合包括斜长角闪岩、TTG片麻岩、花岗闪长岩、片岩和表壳岩等,显示出典型的花岗-绿岩带岩石系列特征,这一岩石系列对了解华北克拉通前寒武纪构造演化以及微陆块碰撞拼合过程具有重要的科学研究意义。本文通过详细的LA-ICP-MS锆石U-Pb年代学分析显示,胶北地体古元古代斜长角闪岩原岩、TTG片麻岩原岩和花岗闪长岩的结晶年龄分别为(1 881±18) Ma、(1 852±16) Ma和(1 840±9) Ma,同时记录了(2 332±32) Ma、(2 244±25) Ma、(1 935±21) Ma的继承年龄和(1 796±17) Ma的变质年龄。锆石Lu-Hf同位素结果显示εHf(t)介于-4.7到3.9之间,地壳模式年龄(T D M c )介于2 784~2 289 Ma之间,表明胶北地体古元古代花岗-绿岩带岩石系列的形成在一定程度上受到了大陆地壳的混染作用。胶北地体古元古代斜长角闪岩具有低硅、高铁、轻重稀土元素分异较弱以及无明显Ce、Eu异常的特点,微量元素显示Nb、Ta负异常和Rb、Pb、K正异常的特征,与板内玄武岩的特征一致。TTG片麻岩和花岗闪长岩呈现出轻稀土元素富集型以及无明显Ce异常的特点,微量元素Nb、Ta、Ti、P的负异常和Rb、Pb、Zr、Hf的正异常等特征,与后碰撞花岗岩和板内花岗岩一致。地球化学特征表明:胶北地体古元古代花岗-绿岩带岩石系列的母岩浆是通过玄武质熔体的部分熔融作用产生的。结合前人研究,本文补充了相关岩石的年龄、同位素和地球化学证据,提出胶北地体存在1.90~1.80 Ga陆-陆碰撞作用,对理解华北克拉通古元古代陆-陆碰撞作用具有重要意义。 相似文献
