Worksheet: Density of Lithosphere and Mantle Rocks Experiment
Caption: SKYLAR VANN (left), Trey Pritchett (middle) and Brea Anderson (right) linger at Mantle Rock, a spot along the Trail of Tears where hundreds of their ancestors were stranded during an unusually harsh winter.
As indicated above, catastrophic plate tectonics posits that massive flooding would have occurred as a result of the melting of hot mantle rock on the ocean floor.
Although nobody has yet found another field like Lost City, Kelley says she's 100 percent sure others exist, because there are so many other places mantle rock has been thrust up through the sea floor, exposing it to seawater and serpentinization.
To better understand how that process works, Sarafian needed to know the temperature at which rising mantle rock starts to melt.
This past weekend, my wife, Amy, and I and our six young kids piled into the van for a trip inspired by "Where They Cried," the article about the mile-long piece of the Trail of Tears near Mantle Rock in Kentucky.
Though scientists tried to emphasize that the two countries were not in competition, the tone at the time was clear: Collecting mantle rock was akin to bringing home bits of the moon.
A sandstone arch called Mantle Rock looms in a nearby hollow, where thick carpets of moss soften the shapes of exposed rock.
In the May 3 Nature, Head and volcanologist Lionel Wilson of Lancaster University in England describe a model of a kimberlite eruption that explains the resulting mix of diamonds, spherules, and mantle rock in a carrot-shaped deposit.
Burke's team found that kimberlites, which are rare volcanic rocks that include diamonds, owe their origin to occasional pulses of hot mantle rock - called mantle plumes - that have risen through the entire thickness of the Earth's mantle from deep down next to the core, or innermost part, of the planet.
That well-established model began to be questioned 8 years ago, when researchers exploring some sections of the slow-spreading Mid-Atlantic Ridge found small, widely dispersed areas of exposed mantle rock on the seafloor.
