The [Marinoan Glaciation](http://en.wikipedia.org/wiki/Marinoan_glaciation) (a.k.a. Elatina Glaciation) was a glaciation that is thought to have occurred towards the end of the aptly-named Cryogenian period at ca. 650Ma. It is particularly known as one of the glaciations that [may or may not](https://earthscience.stackexchange.com/questions/346/what-would-it-take-to-confirm-or-refute-the-snowball-earth-hypothesis) have been a Snowball Earth.

Whether or not this glaciation was truly global, there is evidence that this glaciation existed. But what are the current hypotheses on how this glaciation was triggered?
