degas /diːˈɡas /verb (degases, degassing, degassed)Make or become free of unwanted or excess gas: [no object]: the summit craters were degassing freely...- First, we assume that the magma degassing process is open, meaning that gas and bubbles are lost from the magma during degassing.
- Depending on the initial volatile content of the ‘primary’ or ‘deep’ magma, volatile saturation is reached at a certain point, and the magma begins to degas.
- Faults provide additional pathways, such as dykes, for magma transport and also may help to degas the magma during its ascent.
