Fabric Studies on a 1 Meter-Deep Snow Core from Mizuho Plateau, East Antarctica
Petrofabric analyses were carried out on a snow core from the surface to a depth of one meter obtained at S100 (69°38.1'S; 42°51'E; 1,630m above sea level) in Mizuho Plateau, East Antarctica. In order that the distribution of c-axes of snow crystals was examined, the concept of the value o...
