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.
Is dacite foliated or non-foliated?
Neither. Foliation is a term that applies to metamorphic rocks. Dacite is igneous.
What is the difference in composition between a dacite and an andesite?
Dacite is more felsic in composition, containing more silica.
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 names of extrusive igneous rocks?
== == Rhyolite, basalt, pumice, obsidian, andesite, dacite, tuff, welded tuff, scoria.
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.
What type of rocks come out of a lava dome volcano?
Usually rhyolite or dacite.
Is dacite a metamorphic rock?
No. Dacite is an extrusive igneous rock.
What type of lava does the composite volcano has?
It varies in composition, but is usually andesite, dacite, or rhyolite.
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.
Mount St Helens has layers of this type of rock as well as Andesite through which several domes of Dacite lava have erupted?
The rock type you're looking for is basalt -- St. Helens contains basalt, andesite, and dacite in the form of lava flows and pyroclastic deposits.
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.
Is dacite foliated or non-foliated?
Neither. Foliation is a term that applies to metamorphic rocks. Dacite is igneous.
What is the difference in composition between a dacite and an andesite?
Dacite is more felsic in composition, containing more silica.
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.
