The Smaller the Harder: Theorization of a Threshold Size below which Fluid Inclusions do not Decrepitate

Fluid inclusions are known to be formed at pressures reaching some tens of kilobars. The solid matrix encompassing the fluid filled cavity experiences decompression as a consequence of uplift processes such as eruptions. This event may prompt the mechanical failure of the host-mineral matrix through either stretch or decrepitation, depending on a ductile or brittle mechanism of matrix failure, respectively [1-3].
