Next are three chapters that deal with the origin of magmas, magmatic differentiation, and plate-tectonic settings related to magma generation.
Oil and natural gas are the products of the deep burial and decomposition of accumulated organic material in geologic basins that flank mountain ranges formed by plate-tectonic processes.
They also argue that the hot surface layer would have been too buoyant to sink in subduction zones, and without sinking plates, the whole plate-tectonic cycle grinds to a halt.
‘It solves, in a sense, this 30-year mystery of how the East African rift fits in kinematically in the plate-tectonic scheme,’ says Gordon.
His introduction gives an overview of geologic time, plate-tectonic history, and glaciers to set the stage for the rest of the book.
