Original horizontality - Study guides, Revision notes & Summaries

The Earth's upper mantle is mainly made of peridotite, an ultramafic igneous rock with lots of olivine crystals. Which type of magma can be produced when the upper mantle undergoes decompression melting of the upper mantle peridotite at mid-ocean ridges? - correct answer -Basaltic Seismic studies of the earth have shown that the platnet's interior is made of a few layers with distinct seismic signatures and chemical compositions. The major layers of the planet include (from innermost to the...
