Web20 Oct 2024 · Aplite is a very fine-grained granitic rock that generally occurs as veins and dykes in granitic rocks (Figure 32). The grain size of individual minerals is generally less than 1 mm, and the rock shows a sugary texture. Greisenised granite. Greisenised granite (Figure 33) has an average grain size of 1 mm and exhibits a sugary texture. WebThe general grain size ordinarily is taken as the average diameter of dominant grains in the rock; for the pegmatites, which are special rocks with extremely large crystals, it can refer to the maximum exposed dimensions of dominant grains.
