उदाहरण वाक्य

1. Most pegmatites are composed of quartz, feldspar and mica, having a similar silicic composition as granite.
2. The history of the Huaynaputina region is marked by silicic volcanism, where lava is rich in silica.
3. The silicic acid, when weathered, forms black streaks, which give the rock its characteristic appearance.
4. The rocks follow the calc-alkaline trend of magmatic differentiation, containing silicic lavas such as dacite.
5. This allows the formation of large magma chambers, in which the magma can evolve to more silicic compositions.
6. The magma then continues to migrate upwards causing differentiation and becomes even more sodic and silicic as it rises.
7. Socorro Island is unusual in that it is the only dominantly silicic peralkaline volcanic island in the Pacific Ocean.
8. Another positive attribute of porous silicon is the degradation of porous silicon into monomeric silicic acid ( SiOH4 ).
