A light gray volcanic rock containing a mixture of plagioclase and other crystalline minerals in glassy silica, similar in appearance to rhyolite.
Dacite is used in the construction industry as a building material for monuments, sculpture, and architectural facades due to its durability and appealing aesthetics. It is also used in the production of road construction aggregates and as a component in concrete and asphalt mixtures. Additionally, dacite is sometimes used as a base material for creating ceramic glazes due to its composition of silica and aluminum.
The main difference between dacite and andesite lies in their silica content. Dacite has a higher silica content than andesite, making it more viscous. Dacite also typically contains more quartz and less mafic minerals than andesite.
Neither. Foliation is a term that applies to metamorphic rocks. Dacite is igneous.
Dacite is an extrusive rock while tontalite (along with granodiorite) is an iuntrusive equivalent. While dacite forms on the surface as the result of a volcanic eruption, tontalite forms when magma of a similar composition solidifies underground.
Other intrusive igneous rocks include gabbro, diorite, syenite, monzonite, granodiorite, monzodiorite, anorthosite, troctolite, peridotite, and pyroxeneite. Extrusive igneous rocks include dacite, andesite, phonolite, and trachyte when classified by composition, and tuff, and scoria in terms of texture.
Usually rhyolite or dacite.
It varies in composition, but is usually andesite, dacite, or rhyolite.
No. Dacite is an extrusive igneous rock.
Dacite can be both intrusive and extrusive. Intrusive dacite forms when magma solidifies beneath the Earth's surface, while extrusive dacite forms when lava erupts on the Earth's surface and cools quickly.
Mount St Helens is composed primarily of dacite.
Dacite does not have habitat because it is not a living thing; it is a kind of rock. Specifically, dacite is a volcanic rock, so it will be found on and near volcanoes, typically stratovolcanoes.

Dacite rock can be used for filler in aggregate. It is used to build roads but not on concrete areas because it has a high silica content. Ancient civilization used the dacite rock to make tools.
As with one pound of anything, 1 pound of dacite weighs 1 bound or 0.45 kilograms.
Neither. Foliation is a term that applies to metamorphic rocks. Dacite is igneous.
Mount St Helens erupts dacitic lava, which forms dacite when it cools. Because of the high gas content and high viscosity much of the material gets erupted as ash and pumice rather than lava.
