Oceanic crust covers two-thirds of Earth's solid surface, but scientists still don't entirely understand the process by which it is made. Analysis of more than 600 samples of oceanic crust reveals ...

There are significant P660P waveform anomalies on the front edge of the stagnant Pacific Plate, which was well explained by a simple mineral model that: the segregated basaltic oceanic crust is ...

Rocks with dark minerals, like gabbro and its volcanic variety basalt, make up the oceanic crust, covering two thirds of earth. Every year along the mid-ocean ridges 0.5-0.7 cubic miles of new ...

And the basin itself is so small that it’s hard to identify multiple stripes of the minerals that signify oceanic crust. Read more: Earth’s shrinking crust could leave us living on a water world.

A newly developed method that detects tiny bits of zircon in rock reliably predicts the age of ocean crust more than 99 percent of the time, making the technique the most accurate so far.

Seismic data reveal that there may be hunks of oceanic crust stuck deep within the planet's liquid mantle, ... The stuck slab then separates chemically into differing mineral compositions.

In the Earth's subduction zones, water is transported into the deep mantle by nominally anhydrous minerals (NAMs) and water-bearing minerals in oceanic plates that react with seawater. Therefore ...

The deep part of Earth's middle layer is on the move. New research finds that the lower mantle, located between 410 miles and 621 miles (660 and 1,000 kilometers) beneath the Earth's crust, is ...

The oldest oceanic plates on Earth date back about 200 million years. In contrast, the crust of continents lies under shallow oceans and land. It is highly variable in composition and age.
