Rocks once buried deep in ancient subduction zones—where tectonic plates collide—could help scientists make better predictions of how these zones behave during the years between major earthquakes, ...

An astonishing new rock formation has been revealed in the Colorado Rockies, and it exists in a deeply perplexing relationship with older rocks. Named the Tava sandstone, this sedimentary rock forms ...

Rocks store information from long ago. For instance, their composition can reveal the environmental conditions during their formation. This makes them extremely important in climate research. This led ...

In Earth’s early days, more than 4 billion years ago, the surface was a dangerous and unpredictable place. Violent volcanoes, crashing meteorites, and constant tectonic activity repeatedly resurfaced ...

Researchers working at a sedimentary rock formation in northern Labrador, Canada, say they’ve uncovered evidence of primordial life in 3.95 billion-year-old rocks. The discovery, which is already ...

Sedimentary rocks are made up of pieces of older rocks (igneous, metamorphic, and sedimentary) and organic remains (shells, bone, etc.). When rocks break apart from erosion they are transported by ...

One team of scientists thinks ancient rocks discovered in northern Canada give us a window onto the planet's infancy and the birth of life itself. Another team thinks they're not that special The ...
