What is dacite used for?
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.
What is the difference in composition between a dacite and an andesite?
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.
Is dacite foliated or non-foliated?
Neither. Foliation is a term that applies to metamorphic rocks. Dacite is igneous.
What is the difference between tonalite and dacite?
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.
What are some igneous rocks other than granite basalt pumice rhyolite and obsidian?
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.
What type of rocks come out of a lava dome volcano?
Usually rhyolite or dacite.
What type of lava does the composite volcano has?
It varies in composition, but is usually andesite, dacite, or rhyolite.
Is dacite a metamorphic rock?
No. Dacite is an extrusive igneous rock.
Is dacite intrusive or extrusive?
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.
What type of rock is around mt st Helen's?
Mount St Helens is composed primarily of dacite.
What is the dacite's habitat?
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.

What is the dacite rock used for?
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.
How much does one pound of dacite weigh?
As with one pound of anything, 1 pound of dacite weighs 1 bound or 0.45 kilograms.
Is dacite foliated or non-foliated?
Neither. Foliation is a term that applies to metamorphic rocks. Dacite is igneous.
What type of volcano rock fragment or lava comes out of mt st helens?
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.
