Flood basalts is the term to describe a flow of fluid basaltic lava that issues from cracks or fissures. It commonly covers an extensive area of thickness of hundreds of meters.

How do lava fields form?
They are formed where over time by continual layers of lava building up. They are normally a raised area of land that forms tablelands or flat topped hills. These can go on for hundreds-thousands of kilometres fluid basaltic flows out....
What kind of lava forms shield volcanoes?
Shield volcanoes are fed by basaltic magma.
Do cinder cones produce lava flows?
Yes. Although its typical eruptions produce simple lava flows, there have been cases where water came in contact with magma, triggering explosive eruptions with pyroclastic flows.
If basalt is in lava is the volcano explosive?
No. The more basalt the quieter the eruption. Basalt is deep deep material, from down where there are few volatiles to make lava explosive.
Is a shield volcano and a lava dome volcano the same?
No. A shield volcano is a large, broad sloping volcano that forms over a long period of time as successive low-viscosity basaltic lava flows build on top of one another. A lava dome is a smaller, steep-sloped structure that forms fairly quickly as very viscous lava (usually rhyolite or dacite) builds up, but is too viscous to flow away.
Lava plateaus forms when?
Lava plateaus form when fluid basaltic lava flows out of fissures.

What type of magma forms at mid-ocean ridges?
pillow lava named that because when it cools it looks like pillows.
What kind of lava forms shield volcanoes?
Shield volcanoes are fed by basaltic magma.

Yes. Although its typical eruptions produce simple lava flows, there have been cases where water came in contact with magma, triggering explosive eruptions with pyroclastic flows.
What color rocks does basaltic magma form?
Basaltic magma usually forms a black rock.
If basalt is in lava is the volcano explosive?
No. The more basalt the quieter the eruption. Basalt is deep deep material, from down where there are few volatiles to make lava explosive.

Which igneous rock forms when basaltic lava hardens?
Basalt
Which igneous rock forms when basaltic magma hardens?
Intrusive rock
What type of rock forms from basaltic magma?
Sandstone and limestone and obsidion
What magma is the most abundant of erupted at oceanic spread centers?
The most abundant type of magma erupted at oceanic spread centers is basaltic magma. This type of magma has low viscosity and forms in the mantle part of the Earth that are high in iron and magnesium.
