Latest Lithosphere Stories
New seismic technique detects boundary between old and new lithosphere.
While prospectors and geologists have been successful in finding diamonds through diligent searching, one University of Houston professor and his team's work could help improve the odds by focusing future searches in particular areas.
When it comes to three-dimensional puzzles, Rubik's Cube pales in comparison with the latest creation of Rice University geoscientist Richard Gordon.
An international team of researchers has created the most complete seismic image of the Earth's crust and upper mantle beneath the rugged Himalaya Mountains, in the process discovering some unusual geologic features that may explain how the region has evolved.
By using a super-computer to virtually squeeze and heat iron-bearing minerals under conditions that would have existed when the Earth crystallized from an ocean of magma to its solid form 4.5 billion years ago, two UC Davis geochemists have produced the first picture of how different isotopes of iron were initially distributed in the solid Earth.
Arizona State University researchers say they have discovered a large cylindrical blob of cold material far below the surface of central Nevada. Led by geologist John West, the scientists determined the blob was formed when portions of the lithosphere -- the Earth's crust and uppermost mantle -- had sunk into the more fluid upper mantle beneath the U.S.
Geologists find "blob" of material beneath the US West Great Basin.
The Dead Sea lies in a basin structure situated below the sea level. This deep subsidence is a result of a tectonic concurrence between processes in the upper lithosphere that led to subsiding and a compensating upward flow of rocks in the deeper layers of the lithosphere.
A U.S.-led international team of scientists says it has, for the first time, recorded a geological event that is considered key in shaping the Earth's crust. Led by Purdue University Professor Eric Calais, the researchers said they measured ground displacements as two African tectonic plates moved apart and molten rock pushed its way toward the surface during the first so-called dyking event ever recorded within the planet's continental crust.
Diamonds from Brazil have provided the answers to a question that Earth scientists have been trying to understand for many years: how is oceanic crust that has been subducted deep into the Earth recycled back into volcanic rocks?
Earth science (or geoscience) is the science of the planet Earth. Earth science can be broken down into four major disciplines, which are: geography, geology, geophysics, and geodesy. These disciplines use physics, chemistry, biology, chronology and mathematics to arrive to a greater understanding of the principal areas of the Earth system. Since Earth is the only known life-bearing planet, Earth science is solely dedicated to the geophysical makeup of our own planet. One discipline,...
- A small wooded valley; a dell.
- The protecting weather-shed built around the entrance to a house.
- The roofed-over space between the kitchen and the sleeping-quarters in a logging-camp, commonly used as a storeroom.
