The Evolution of Modern Continents,es. In the earliest Hadean era, these made thick basaltic plateau that gradually, and partially, melted at their bases to produce TTGs and lots of komatiite and basalt: greenstone belts. An alternative model, involving the stacking up and partial melting of blocks of basaltic-komatiitic crust, is sh

Plate Tectonics, Planetary Magnetism and Life, field that diverts most of the solar wind. While the magnetic field does not guarantee protection from the ravages of the Sun, it does divert the wind’s erosive flow from the outskirts of our atmosphere. In this chapter, we examine how such a field comes about; whether the Earth has always had it;
