The pressure necessary to spur decrepitation is reliant upon the size of the fluid inclusions; bigger inclusions decrepitate more easily at pressures between 700-900 atmospheres, while smaller fluid inclusions may require upwards of 1200 atmospheres, contrastingly, when fluid inclusions become even smaller, the amount of pressure applied will have no effect and decrepitation will not occur.

However, recent studies of fluid inclusions in chrome spinels from the cumulate zones of komatiite flows have shown that a single komatiite flow can be derived from the mixing of parental magmas with a range of Al 2 O 3 / TiO 2 ratios, calling into question this interpretation of the formations of the different komatiite groups.
