a plateau
When large amounts of lava flow out of fissures onto land, the lava can cover a large area and form a plain called a lava plain or a basalt plain.
These flows are known as pyroclastic flows.
Crater or vent. Sometimes lava also comes from fissures as well. However crater is the most commonly used term.
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.
I don't think it's exactly a plain you're looking for. Magma erupting out of a fissure and spreading over a large area leads to the formation of thick solidified sheets of lava. After later eruptions, more sheets pile up to form extensive, flat topped lava plateaus.
A lava butte is generally basaltic lava. Granitic lava flows (called rhyolitic when they form at the surface) are rare and do not cover much ground.

Lava plateaus form when fluid basaltic lava flows out of fissures.

A substance that flows is called a fluid

statement of cash flows
A substance that flows is called "liquid".
A stream or river called that flows into a larger stream or river is called a tributary.
