Exempel på hur man kan använda SILICIC i en mening

• Most pegmatites are composed of quartz, feldspar, and mica, having a similar silicic composition to granite.
• In 1858, he pointed out the isomorphism of the fluostannates and the fluosilicates, thus settling the then vexed question of the composition of silicic acid.
• Socorro Island is unusual in that it is the only dominantly silicic peralkaline volcanic island in the Pacific Ocean.
• This mountain has produced andesite, basalt and dacite, with relatively silicic andesite dominant in recent eruptions.
• By the 16th Century, mineralization of the mine's tailings and slag added by smelters began to produce a red-coloured sludge rich in copper, limonite, silicic acid, and zinc.
• In turn, the Stevens Ridge Formation overlies the Ohanapecosh layer, featuring quartz-bearing silicic tuff, rhyolite, and other volcaniclastic rocks.
• It is constructed by lava flows that range in composition from basaltic andesite bordering on trachyandesite over dacite and smaller flows of partially silicic magma.
• Mogollon-Datil volcanic field, a large silicic volcanic field in western New Mexico (Mogollon Mountains—town of Datil area).
• They are dominantly mafic, but also can have significant ultramafic and silicic components, and some are dominated by silicic magmatism.
• Abu Mansur distinguished between sodium carbonate and potassium carbonate, and seems to have had some knowledge about arsenious oxide, cupric oxide, silicic acid, and antimony; he knew the toxicological effects of copper and lead compounds, the depilatory vertue of quicklime, the composition of plaster of Paris, and its surgical use.
• Silicic acid readily condenses to give "higher" silicic acids including disilicic (pyrosilicic) and cyclo-tetrasilicic acid, :.
• This was accompanied by small volumes of more silicic volcanism, producing trachyte, trachydacite, and rhyolite tuffs, domes, and plugs.
• It has been known for years that silica sols (also known as colloidal silica, silicic acid, polysilicic acid) will gel when exposed to temperatures around 0 °C (32 °F).
• Diatoms need, among other nutrients, silicic acid to create biogenic silica for their frustules (cell walls).
• In discussions about the location of biblical Mount Sinai, Jabal Maqlā ('Burnt Mountain') is often believed to be Jabal al-Lawz by various authors such as Bob Cornuke, Ron Wyatt, and Lennart Möller as shown by local and regional maps In contrast to the real Jabal al-Lawz, the summit of Jabal Maqlā consists mainly of dark-colored hornfels derived from metamorphosed volcanic rocks that originally were silicic and mafic lava flows, tuff breccias, and fragmental greenstones.
• Most of the surrounding volcanoes consist of mafic (basaltic) lavas; only South and Middle Sister have an abundance of silicic rocks such as andesite, dacite, and rhyodacite.
• Gaua is rare in hosting a mafic ignimbrite, as most similarly explosive eruptions are more silicic; other examples include Masaya in Nicaragua, and on Ambrym, and Tanna, also in Vanuatu.
• The immense volumes of magma involved in batholiths can force their way upwards only when the magma is highly silicic and buoyant, and are likely do so as diapirs in the ductile deep crust and through a variety of other mechanisms in the brittle upper crust.
• Recent work has successfully correlated the Upper Section Peak Formation, as well unnamed deposits in Convoy Range and Ricker Hills with the Lower Hanson, all likely of Sinemurian age and connected by layers of silicic ash, while the upper section has been found to be Pliensbachian, and correlated with a greater volcanic pulse, marked by massive ash inputs.
• Compared to the nearby vent zone surrounding Mount Mazama, it has a lower density of volcanic vents, no dacitic or silicic volcanic rock, and a lower volume of eruptive material produced during the Quaternary.
