Aplites are often associated with pegmatites. Learn more about Pegmatite vs Aplite in the next section. When we have to compare Aplite vs Pegmatite, the texture, color and appearance plays an important role in determining the type of rock. 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. Their origin and petrogenetic relationships with the widespread granitoids have led to a currently rekindled discussion about anatectic vs. granitic origin for the pegmatitic melts. They have been observed in association with the granite masses only at one locality in the state. on the first line The hardness of Pegmatite is 7 and that of Aplite is 6.5. One phyllosilicate has been paid too little attention to during the recent past. The eastern Sierras Pampeanas. Pegmatitic magma is rich in volatile constituents which makes it significantly less viscous. Aplites are the fine-grain equivalent of granite and composed only of quartz and alkali feldspar, and very small amounts of muscovite and biotite. The streak of Pegmatite and Aplite is white. Appearance of Pegmatite is Layered, Banded, Veined and Shiny and that of Aplite is Veined or Pebbled. 4.

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism. K-Mn oxides and uranyl phosphates are key minerals for the chronological dating of the supergene alteration of the pegmatites. Oh My!!" Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism. Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors whereas, Aplite is available in black, grey, orange, pink, white colors. Aplite and Pegmatite have mineral and chemical composition very close, but they differ mainly in the crystal size and the position of each rock together. Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals. Dyke swarms of granitic aplite-pegmatites in metasedimentary rocks with drift, Portugal. These rocks are composed of many distinct minerals. The hardness of Aplite is 6.5 and that of Pegmatite is 7.

We focus our subsequent discussion on the Himalaya and George Ashley dikes because they display between them various features common to many pegmatite-aplite dikes. Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma. The eastern Sierras Pampeanas are mainly composed of metamorphic rocks, intruded by dominant granitic melts (e.g., Toselli et al., 1986; Rapela et al., 2001; Miller and Söllner, 2005). In contrast, most pegmatite-aplite dikes display changes in crystal size from <0.1 mm in aplites, to >10 cm for crystals in the hanging wall, core zone, and pockets.
