Very large impacts may have stimulated blasts of plate tectonics

A new study suggests that the Earth's evolution from a hot, primordial mush into a rocky planet continuously resurfaced by plate tectonics may be triggered by extraterrestrial impacts. By examining the implications of these processes, the researchers believe...

Research suggests major changes to geology textbooks

A new research of the Earth’s crust and upper-mantle suggests that ancient geologic events may have left deep ‘scars’ that can come to life to play a role in earthquakes, mountain formation, and other ongoing processes on our planet. This changes...

Collapse of Earth's tectonic plates unravelled

Following the international expedition drilling into the Pacific ocean floor, the scientists have for the first time discovered what happens after one tectonic plate gets pushed under another, Australian National University reports. During the drilling expeditions,...

A new answer to a long standing question of how plate tectonics started on Earth

An international team of geologists have proposed a new answer to a long standing question how plate tectonics started on Earth in the first place. They were able to demonstrate how the first sinking of litospheric plates, which is a key process of plate tectonics,...

First microplate discovered in the Indian Ocean reveals the age of Himalayas

The first ancient oceanic microplate has been discovered in the Indian Ocean by a team of Australian and US scientists. The discovery helped in identifying the timeline in which the initial collision between India and Eurasia has taken place, an event which gave...

New research shows Chinese continental shelf of exotic origin collided with continental China 100 million years ago

Researchers from China and United Kingdom have introduced a new hypothesis about the tectonic evolution of the greater western Pacific since the Mesozoic era, which shows that the basement of the Chinese continental shelf is geologically unrelated to the continental lit

A cause for plate collision discovered

An international team of 30 scientists has traveled to the Philippine Sea to drill into the crust of the Izu–Bonin-Mariana (IBM) arc and discover a cause for the plate collision. The results of their research were published in Nature Geoscience Journal on August 2

Study reveals how dust inside faults may contribute to earthquakes

A new study looks at how powdery material inside faults may contribute to earthquakes. According to geologist Ze'ev Reches of the University of Oklahoma in Norman, US, the gradual buildup of stress in a fault as plates collide or slide past each other is

earth mantle molten layer

Previously unknown magma layer in Earth's mantle offers new insights into tectonics

Scientists have debated for decades as to what forces allow the planet's tectonic plates to slide across the Earth's mantle. Now, researchers have found a layer of liquefied molten rock in Earth's mantle, which could potentially be that cause of the tectonic

Plate tectonics discovered on Mars

A UCLA scientist has discovered that the geological phenomenon known as "plate tectonics", which involves the movement of huge crustal plates beneath a planet's surface, also exists on Mars. An Yin, planetary geologist and a UCLA professor of Earth and space sciences

New study focused on Nazca Plate shows a link between the shape of plate boundaries and the forces they exchange

A new study of tectonic plate boundaries may help scientists understand how earthquakes happen. The work by researchers including Dr Giampiero Iaffaldano from the Australian National University focused on the Nazca plate, which plunges beneath the continental South

Scientists drill into San Andreas Fault to understand its secrets came across a video of the National Science Foundation that explains what scientists are currently doing to understand what is going on inside the San Andreas Fault. The video has been aired in the PBS NewsHour. Understanding what happens at...

Scientists claim that Earth is not expanding

Since Darwin's time, scientists have speculated the planet might be expanding or contracting. Even with the acceptance of plate tectonics half a century ago, which explained the large-scale motions of Earth's outermost shell, the accusations persisted; some Earth and

Hotspots driving tectonic plate movement

Plate tectonics has been on the curriculum for a while now. Most people are fairly familiar with the theory; the Earth's crust - or lithosphere - is broken up into different plates which move around on the very hot, viscous substance beneath.This movement is driven
