What is the composition of magma of popocatepetl?
A mixture of dacite (65wt% SiO2) and basaltic andesite (53wt% SiO2).
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.
A light colored igneous rock with silica content and explosive eruptions?
Andesite
What kind of lava flows from Popocatepetl?
Popocat?petl produces a mixture of andesitic and dacite lava in the current cycle of activity. Andesitic, or Basaltic Andesite, is black volcanic rock that contains 55% silica. Dacite, on the other hand, is an igneous, volcanic rock that has a composition that is between Andesite and Rhyolite.
What type of lava does mount st helens have?
Mt St Helen's eruption of 1980 was a pyrocastic flow diverse lava, ranging from olivine basalt to andesite and dacite). The magma is believed to come from another area laterally located to the east. Magma and rock under the volcano are cool.
Does mt st helens erupt andesite rock?
In some cases, yes. However the most recent eruptions have produced dacite.
What is the difference in composition between a dacite and an andesite?
Dacite is more felsic in composition, containing more silica.
What type of lava does the composite volcano has?
It varies in composition, but is usually andesite, dacite, or rhyolite.
