Petroleum inclusions are the intact and original gas and oil samples trapped in minerals in the process of geological evolution of basins containing oil and gas(Liu et al.,2003).
Sichuan is one of the most important gas-producing provinces in China.It is a basin with the most discovered gas fields and the greatest annual gas production in China.
Recent investigations carried out over the Amik basin(SE Turkey)** located at the Arabian-African plates boundary,highlighted a diffuse degassing of mantle-derived volatiles mainly composed by CO2 wit
Helium isotope ratios are the best tool to evaluate the source of fluids and to distinguish between upper mantle and crustal origin of volatiles,because the two reservoirs are clearly different in the
Strong,subcontinental mantle-dominated CO2 degassing occurs in the Hartou(s)ov and Bublák mofette fields in the western Eger Rift(Br(a)uer at al.,2008).
Authigenic carbonates occurring as chimney-like morphologies were recovered from the Shenhu area,northern South China Sea at 400 m water depth and their mineralogy,isotopic compositions and lipid biom
