As with many stratovolcanoes, the type of activity at Mount St Helens varies. In its famous 1980 eruption it produce massive clouds of ash and pumice and later built a lava dome. The rock formed was dacite. However, other material has erupted in the volcano's past, including basaltic lava flows.

Large angular volcanic fragments are called?
Volcanic fragments are small pieces of rock that come from a volcano. Fragments are usually thrown in the air during a volcanic eruption.
What type of volcanic fragments come out of lassen peak?

Did mt st helens have lava come out when it erupted?
No
What type of volcanic rock fragments or lava come out of mt. Pinatubo?
Analysis of deposits suggets that many of Pinatubo's eruptions are similar to the one that occurred in 1991. This eruption produced enormous clouds of ash and pumice.
Where does the ash of a volcano come from?
The ash of a volcano comes from the pulverized rock and mineral fragments that are ejected during an explosive eruption. These fragments can vary in size, from tiny particles to larger chunks of volcanic debris. The ash is carried into the atmosphere by the force of the eruption and can travel long distances, settling on the ground as a layer of fine particles.
What was mount saint helens created by?
it was created by magma in the earth's core and when all the volcanic gasse come out it exploded and is now what it is

What type of volcanic rock fragments or lava come out of the kilauea volcano?
Kilauea generally produces lava flows and lava fountains. Its current activity has also involved the formation of lava lakes. All of the lava involved is basaltic.

Where did Hawaii come from?
The islands were created by volcanic activity.
Did obsidian come out of mt st Helens?
Interesting question. After the explosive eruption, the gas content of the rhyolitic magma should have decreased enough to allow obsidian to form. It is the right kind of lava. However, most of the lava dome in the Mount St. Helens caldera is dacite, which is "grainier" than obsidian, indicating that it cooled too slowly to have a "glassy" appearance. Obsidian flows must cool quickly to prevent crystal formation. It is possible that some obsidian was formed, but subsequently covered by dacite. I have not been able to find any reports that mention obsidian recovered from the Mount St Helens lava dome.So the answer is a qualified no, we don't have any evidence of obsidian flows from Mount St Helens.Incidentally, there are individuals and companies selling products they call "helenite" or "St Helens Obsidian", which is a synthetic material created by fusing volcanic ash (which may or may not have come from Mount St Helens).
How does volcanic rock form?
Volcanic rock forms by lava that has come from a volcano, cools and solidifies to form the rock.
Where did the word Saint Lawrence come from?
The word "Saint Lawrence" originated from the name of the Christian martyr Saint Lawrence, who was a deacon in the early Christian Church. He was known for his acts of charity and was martyred in Rome in the 3rd century.
