A schematic image of subducted oceanic crust inferred from this study. Basalt and harzburgite layers of the oceanic crust accumulate beneath and above the 660 km discontinuity, respectively.

Figure 4: Pressure–temperature diagram showing generalised carbonate phase relations in subducted, carbonated oceanic crust. The melting curves of carbonated basalt at upper mantle and transition zone ...

and injecting it into underground basalt. Within two years, the CO2 gas mineralizes, becoming rock deep underground. These ...

A long-lost oceanic plate is diving deep into the mantle, dragging down the crust above, researchers say. However, the plate is also tearing apart below the Zagros Mountains in Iraq as it plunges ...

uncovering a dramatic separation between Earth's crust and mantle under the Sierra Nevada. One theory suggests wet basalt melts under high pressure, allowing minerals to layer into distinct sheets.

The diagram below shows the structure of the earth. In geography, taking a slice through a structure to see inside is called a cross section. Continental plates are usually quite thick (between 35 ...
