A new geological study reshapes the timeline of a major tectonic collision that helped form the Andes, suggesting key events occurred earlier than long assumed.

A new international study published in Earth and Planetary Science Letters reveals that the boundaries between geological epochs and periods, even though randomly distributed, follow a hidden, ...

The pattern of geological boundaries may not be as unstable as people have thought, as these boundaries exist between geological wedges of time, like eons, periods, and epochs. Each of these wedges is ...

Scientists at Curtin University have uncovered a new way to read the deep history of Earth’s landscapes using microscopic zircon crystals from ancient beach sands. These incredibly durable minerals ...

The continental collisions that created this narrow Mideast waterway endowed the region with its petrochemical riches—and ...
