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 is the difference in composition between a dacite and an andesite?
Dacite is more felsic in composition, containing more silica.
Is dacite foliated or non-foliated?
Neither. Foliation is a term that applies to metamorphic rocks. Dacite is igneous.
What is dacite used for?
Dacite is a type of extrusive rock that is classified in the volcanic group. This rock is used in construction and building roads.
Dacite is what type of?
A light gray volcanic rock containing a mixture of plagioclase and other crystalline minerals in glassy silica, similar in appearance to rhyolite.
What is the difference between eluviation and leaching?
what is the difference between elevation and leaching
What is the difference in composition between a dacite and an andesite?
Dacite is more felsic in composition, containing more silica.
Is dacite a metamorphic rock?
No. Dacite is an extrusive igneous rock.
Is dacite intrusive or extrusive?
Dacite is extrusive. Its intrusive equivalent is granodiorite.
Which volcanoe have eruptions of andesite and dacite?
Andesite and dacite are produced by stratovolcanoes.
What is dacite and rhyodacite?
Rhyodacite are both intermediate-felsic volcanic rocks. They form from the eruption of highly viscous silica rich magma. In terms of composition dacite is in between andesite and rhyolite while rhyodacite is in between dacite and rhyolite. They are similar rocks, generally erupting explosively but occasionally forming lava domes or very thick lava flows.
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.
Is dacite foliated or non-foliated?
Neither. Foliation is a term that applies to metamorphic rocks. Dacite is igneous.
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.
What is dacite used for?
Dacite is a type of extrusive rock that is classified in the volcanic group. This rock is used in construction and building roads.
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.
What are some names of intrusive igneous rocks?
Granite, Gabbro, Diorite, Syenite, Monzonite, Tonalite
How fast does dacite lava flow compared to mafic lava?
Dacite lava flows at speeds orders of magnitude slower than mafic lava.
