Rocks are quarried from many years for various purposes. They are mostly fine grain, white to light gray. Aplite and pegmatite.-Careful field study of the larger and principal granite areas in Georgia, by the writer, indicates the general absence of true aplites therefrom. Les aplites sont associés, soit à des roches magmatiques, soit à des roches métasomatiques. Aplite (/ ˈ æ p l aɪ t /) is an intrusive igneous rock in which the mineral composition is the same as granite, but in which the grains are much finer, under 1 mm across. Aplite, any intrusive igneous rock of simple composition, such as granite composed only of alkali feldspar, muscovite mica, and quartz; in a more restricted sense, uniformly fine-grained (less than 2 millimetres [0.08 inch]), light-coloured, intrusive igneous rocks that have a characteristic granular texture. Aplite is a fine-grained granite composed mainly of feldspar and quartz. It's located in California, United States.The dikes are in a road cut along the highway. Properties of rock is another aspect for Aplite vs Pegmatite. Also you can check about Properties of Aplite and Properties of Pegmatite. The composition of Pegmatite and Aplite consists of mineral content and compound content. Small scale tight folds are numerous in calc-silicate rocks and are faithfully followed by the associated aplite bands (Fig.2).
