| 1 | Primary migration and secondary alteration of the Upper Paleozoic gas reservoir in Ordos Basin,China―Application of fluid inclusion gases显示文摘The composition of fluid inclusions(FI)often represents the initial geochemical characteristics of palaeo-fluid in reservoir rock.Influence on composition and carbon isotopic composition of gas during primary migration,reservoir-forming and subsequent secondary alterations are discussed through comparing fluid inclusion gas with coal-formed gas and natural gas in present gas reservoirs in the Ordos Basin.The results show that primary migration of gas has significant effect on the molecular but not on the carbon isotopic composition of methane.Migration and diffusion fractionation took place during the secondary migration of gas in Upper Paleozoic gas reservoir according to carbon isotopic composition of methane in FIs.Composition and carbon isotopic composition of natural gas were nearly unchanged after the gas reservoir forming through comparing the FI gases with the natural gas in present gas reservoir. | GONG Se 1,2 ,PENG PingAn 1 ,SHUAI YanHua 3 ,DAI JinXing 3 &ZHANG WenZheng 4 1 Guangzhou Institute of Geochemistry,the Chinese Academy of Sciences,Guangzhou 510640,China 2 Common Wealth Scientific and Research Organization,Petroleum Resources,PO Box 136,North Ryde,New South Wales,1670,Australia 3 Research Institute of Petroleum Exploration and Development,PetroChina,Beijing 100083,China 4 Research Institute of Exploration and Development,Changqing Petroleum Corporation,Xi’an 710021,China | 2008 | Science China Earth Sciences2008，51，S1： | 3 |

| 5 | Almandine megacrysts from Yingfengling Cenozoic basalt in Leizhou Peninsula and their parental magma origin显示文摘The garnet megacrysts from Yingfengling basalts are characterlzed by high FeO (>20%), CaO (7.02% -8.16%) and low MgO (5.88%-10.87%). Significant composition variations are observed in these megacrysts, of which Ni, V, Sc, Co, and HREE are positively correlated with their Mg# and Zr, Hf, Ga, Y, Sr, Nb, Zn and LREE-MREE are negatively correlated with Mg#. Megacryst parent magma is a highly evolved residual melt with strongl depletion in Ti, Sr, Hf, Nb and HREE. This parental magma was generated by more than 60% of crystallization fractionation of clinopyroxene, garnet, plagioclase and ilmenite from quartz tholeiitic magma. It has not erupted to the surface, but stayed at the upper mantle and formed the megacrystic cumulate. Megacrysts and their host basalt are in disequilibrium. | YU Jinhai & S. Y. O’Reilly1.
