Taiwan experiences some of the world's fastest rates of mountain building -- they are growing at a faster rate than our fingernails grow in a year. The mountains also see frequent and significant ...
The Martian surface presents a complex record of geological processes that have spanned billions of years. The planet’s topography reveals evidence of volcanic activity, impact cratering, fluvial ...
A new analysis of rocks thought to be at least 2.5 billion years old helps clarify the chemical history of Earth's mantle -- the geologic layer beneath the planet's crust. The findings hone scientists ...

Gold has always been a hot commodity. But these days, finding a nugget isn’t too tricky: Much of the world’s gold is mined from natural veins of quartz, a glassy mineral that streaks through large ...
TORONTO, ON - Geoscientists at the University of Toronto (U of T) and Istanbul Technical University have discovered a new process in plate tectonics which shows that tremendous damage occurs to areas ...
There are 35 large Archean cratons around the world that form the geologic core of tectonic plates. Because they’re located at the interior of plates, these landmasses often remain unaltered over the ...
The water pressure of a river can cut deep into a riverbed. Sediments from the riverbed are carried downstream, creating a deep, narrow channel. This process, known as downcutting, represents the ...
A thin slice of the ancient rocks collected from Gakkel Ridge near the North Pole, photographed under a microscope and seen under cross-polarized light. Field width ~ 14mm. Credit: E. Cottrell, ...
