Internal melt figures in ice by rapid adiabatic Compression
Single crystals and bicrystals of water ice have been adiabatically pressurized to produce, and clearly illustrate, two types of internal melt figures: (1) dendritic figures that grow from nucleation imperfections on the specimen's surface, or from air bubbles at grain boundaries, into the ice...
