yellowstone hotspot造句

• The source of the Yellowstone hotspot is controversial.
• Ash from a Yellowstone hotspot eruption 10-12 million years ago created these fossilized bone beds.
• The Mackenzie hotspot is interpreted to have been similar to the early volcanism of the Yellowstone hotspot.
• The size of these eruptions and their location in this region is attributed to proximity to the Yellowstone hotspot.
• The Yellowstone hotspot is responsible for volcanism at the Yellowstone Caldera and a series of extinct calderas along the Snake River Plain.
• But whereas the Yellowstone Hotspot reflects the motion of the North American plate across a hotspot, the Newberry track does not.
• Both flows are similar in both composition and age, and have been attributed to a common source, the Yellowstone hotspot.
• Some geoscientists hypothesize that the Yellowstone hotspot is the effect of an interaction between local conditions in the lithosphere and upper mantle convection.
• This age progression mirrors the very similar progression along the track of the Yellowstone Hotspot, which appears to have a common origin.
• The eastern Snake River Plain traces the path of the North American plate over the Yellowstone hotspot, now centered in Yellowstone National Park.
• The short time span of two million years for magma emplacement in the Mackenzie Large Igneous Province is also present for the Yellowstone hotspot.
• Sometime between 10 and 15 million years ago, multiple lava flows poured out from the Yellowstone hotspot, then located in western Idaho.
• To the southwest of the caldera lies the Snake River Plain, which was formed by a succession of older calderas marking the path of the Yellowstone hotspot.
• The track of the Yellowstone Hotspot is neatly explained by motion of the North American craton over a plume ( hotspot ) of material rising from the mantle.
• Of the many calderas formed by the Yellowstone Hotspot, including the later Yellowstone Caldera, the Henry's Fork Caldera is the only one that is currently clearly visible.
• Of the many calderas formed by the Yellowstone hotspot, including the later Yellowstone Caldera, the Henry's Fork Caldera is the only one that is currently clearly visible.
• Solitary Mountain consists of Late Cretaceous volcanics of the Carmacks Group, a volcanic group that may have its origin from volcanism of the Yellowstone hotspot some 70 million years ago.
• Likewise to the east, where both the OWL and the Brothers Fault Zone become less distinct in Idaho where they hit the old North American continental craton and the track of Yellowstone hotspot.
• This track, and its implication of a moving source, roughly mirrors the similar track of the Yellowstone Hotspot from the hotspot ( a plume of hot material arising from the earth's mantle ).
• The various geyser basins are located where rainwater and snowmelt can percolate into the ground, get indirectly superheated by the underlying Yellowstone hotspot, and then erupt at the surface as geysers, hot springs, and fumaroles.
