It is unknown, but it is probably a magnesium silicate known as post-perovskite (MgSiO3). It is composed of the prime oxide constituents of the Earth's rocky mantle, magnesium oxide and silicon dioxide. You may think water is more common, but even the oceans which we think of as unfathomably deep make for an incredibly thin layer of the planet compared to its diameter.
