No it is caused by rapid oxidation.
In general, oxidation is the loss of electrons and reduction is the gain of electons. When something is oxydized, the oxidation number will increase and when something is reduced the oxidation number...

Increases to more positive so for example X3- going to X2- is oxidation.Fe2+ going to Fe3+ is also oxidation as is Metal going to Metal n+
