| 英文摘要 | Dasonite, NaAlCO3 (OH)(2), is widespread as a cement and replacement in sandstone from Nantun Formation and Damoguaihe Formation of the lower Cretaceous in Wuerxun sag, Hailaer basin. The origin of the carbon in dawsonite is studied by stable isotope composition. Dawsonite delta C-13 (PDB) values range from -5.253 parts per thousand to -1.210 parts per thousand and are remarkably consistent. delta O-18(PDB) values range from -24.896 parts per thousand to -20.960 parts per thousand. These values indicate magmatic source for carbon in the dawsonite in the view of the fact that carbonate rock is not available in all exploratory well in Hailaer basin. It can be concluded that the coupling between magma activity, diagenesis of sandstone (including the form of dasonite) and CO2 gas reservoir is fine either in composition or in space-time according to the calculated delta C-13 values of CO2 gas in isotope equilibrium with dawsonite and the coincidence of dawsonite-containing well and CO2 gas well, lying along deep fracture within or adjacent to granite during Stage of Yanshan. Consequently, CO2 gas forming dawsonite is derived from mantle related to magmatic process during Stage of Yanshan. And deep fracture is main channel transporting CO2 gas from the deep to shallow sandstone. A little biologic origin carbon owing to petroleum charging intervened when dawsonite formed. |
