1.Introduction Geogas propecting was put forward to find concealed deposits and concealed structure by Boliden Mineral and Lund university since 1980(Malmqvist et al.,1984;kristiansson et al.,1987).
Compound-specific of isotope analysis(CSIA)of normal-level hydrocarbons is an effective indicator for oil and gas research,and it has been successfully used for assessing the natural gas maturity,corr
1.Introduction 2013,China has become one of the biggest industrial world powers in the world.And,Environment pollution is increasingly serious with dust-haze(Wang et al.,2014).
Flash pyrolysis(Py)in combination with gas chromatography(GC)and mass spectrometry are often used to elucidate the structure of geomacromolecules such as kerogens,coals,asphaltenes and humic acids by
It is an important topic for geochemist to evaluate petroleum source rocks precisely from spatial and temporal scales in highly explored area like Liaohe Basin.
Recent researches have indicated that,beside volcanic eruption periods,dormant periods between the volcanic activities can emit a large amount of CO2 from the solid earth into atmosphere.
