Don't spend too much time on evaluating luster of rock samples. Make sure you observe other properties (e.g., hardness, streak, cleavage, etc.) Here are some examples of luster in rocks (multi-crystalline aggregates) where crystals approach microscopic in size, making luster more difficult to evaluate. Metallic luster - single crystal of graphite.At least some rock glaciers do indeed have glacier ice cores (despite the controversy about the model's validity, see below). Figure 4 shows an example, from Galena Creek Rock Glacier, of an ice core showing typical banding due to the winter accumulation of snow that was turned into the ice of a small glacier, later to be covered by debris.Rhyolite (Early Proterozoic) at surface, covers 0.4 % of this area.
