Short summary

Crystal orientation fabrics and microstructures in the deep sections of the Dome Fuji (DF) ice core were investigated using innovative methods with dense depth coverage. Together with our previous studies, we have obtained whole layer profiles of the crystal orientation fabric and physical properties of the DF ice core. Development and fluctuation of the crystal orientation fabric were found to be highly dependent on impurity concentrations and recrystallization processes.
