Like many stratovolcanoes, Mount St Helens has produced material of mafic, felsic, and intermediate composition. Overall, much of the material is itermediate. The 1980 eruption and later activity have produced dacite, which has an intermediate-felsic composition

Do cinder cones erupt felsic or mafic lava?

Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.


What type of lava Mount Vesuvius?

Mt. Vesuvius produces felsic lava in a pyroclastic explosion.


Which moves fast felsic lava or mafic lava?

A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.

What is the composition of Mount Rainier?

Mount Rainier is composed mainly of andesite lava flows, lahars (mudflows), and volcanic ash. The mountain is also covered by glaciers which contribute to its iconic snow-capped appearance.

What type of lava does Mount Rainier have Aa or Pahoehoe?

Mount Rainier primarily has andesitic lava, which can exhibit characteristics of both Aa and Pahoehoe types. However, the predominant lava flows associated with Mount Rainier are typically more akin to Aa, as they are often cooler and more viscous, resulting in a rough, jagged surface. Pahoehoe, which is smoother and more fluid, can occur but is less common in this region.

What type of lava does mt rainier erupt?

Mount Rainier is a stratovolcano that typically erupts andesitic lava, which is a viscous type of lava that can lead to explosive eruptions. This lava tends to build up pressure before erupting, creating the potential for large ash clouds and lahars.


What type of lava forms mt rainer?

Mount Rainier is composed primarily of andesite lava, which is an intermediate type of lava that has a higher silica content compared to basaltic lava. This type of lava is more viscous, leading to explosive eruptions and the formation of volcanic cones like Mount Rainier.


Between mafic lava and felsic lava which flowsfaster?

Mafic lava is hotter than felsic lava and therefore flows faster.
