Triple

Target entity: Columbia River Basalt Group
Context triple: [Vantage, Washington, geology, Columbia River Basalt Group]

• A. Columbia River Basalt Group chosen
  The Columbia River Basalt Group is a vast Miocene-age large igneous province in the Pacific Northwest composed of extensive flood basalt lava flows that blanket parts of Washington, Oregon, and Idaho.
• B. Absaroka Volcanic Supergroup
  The Absaroka Volcanic Supergroup is a large sequence of Eocene-age volcanic rocks in the Rocky Mountains of Wyoming and Montana, representing one of the most extensive ancient volcanic fields in the region.
• C. Cascade Range volcanic province
  The Cascade Range volcanic province is a major volcanic region in western North America characterized by a chain of active and dormant stratovolcanoes and extensive volcanic deposits formed by the subduction of the Juan de Fuca Plate beneath the North American Plate.
• D. Snake River Plain volcanic fields
  The Snake River Plain volcanic fields are a series of extensive basaltic lava flows and volcanic features in Idaho that record the westward track of the Yellowstone hotspot across the Intermountain West.
• E. Idaho batholith
  The Idaho batholith is a massive granitic intrusive rock complex in central Idaho that formed during Late Cretaceous magmatism and is one of the largest batholiths in North America.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
