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.
Along with the in-depth exploration for the natural gas of the Upper Palaeozoic in Ordos Basin,the natural gas exploration of the Upper Palaeozoic in Sulige Area has gained more and more attentions.
CH4 and CO2 are atmospheric greenhouse gases(GHG)generated from both natural and anthropogenic processes.GHG emission from geological sources such as volcanic activity,seabed gas hydrate release,hydro
Changbaishan volcano,~1400 km away from Pacific subduction zone,has long been regarded as significant source of carbon released by episodic eruptions since Quaternary and magma-related geothermal acti
Deep-seated carbon could be transported from Earths interior into atmosphere by volcanic activities,which play an important role in geologic carbon degassing and its effects on global climate.
The solid earth degassing was enhanced by the 12 May 2008 Wenchuan MS 8.0 earthquake,resulting in large amounts of carbon-bearing gases emitted into the atmosphere.
