Description: Research Report
Summary: The results of petrofabric studies in the laboratory on five samples of high-density snow collected in 1954 and 1955 at depths of 8.0, 15.5, 23.0, 34.2, and 46.3 m in a pit at Site 2 are reported. The porosity of the samples, the number of grains/cm^2, the mean number of adjacent grains per grain, the mean grain cross section, the size distribution of grain cross sections, and the orientation of c-axes were determined from enlarged photomicrographs of thin sections, using reflected light and transmitted polarized light. The number of adjacent grains per grain, the ratio of free to occupied grain surface, and the sphericity clearly depended on porosity and on each other. There was no strong relation between these data and the number of grains/cm^2. Hence, the structure of high density snow can be satisfactorily described by the porosity and the number of grains/cm^2 . Conclusions from a two-dimensional thin section can be applied to a spatial sample only if the sample is isotropic by strata.
