Whole-earth decompression dynamics

摘要

The principles of whole-earth decompression dynamics are disclosed leading to a new way to interpret whole-earth dynamics. Whole-earth decompression dynamics incorporates elements of and unifies the two seemingly divergent dominant theories of continental displacement, plate tectonics theory and earth expansion theory. Whole-earth decompression is the consequence of earth formation from within a Jupiter-like protoplanet, with subsequent loss of gases and ices and concomitant rebounding. The initial whole-earth decompression is expected to result in a global system of major primary decompression cracks appearing in the rigid crust, which persist as the basalt feeders for the global, mid-oceanic ridge system. As the earth subsequently decompresses, the area of the earth's surface increases by the formation of secondary decompression cracks, often located near the continental margins, presently identified as oceanic trenches. These secondary decompression cracks are subsequently in-filled with basalt, extruded from the mid-oceanic ridges, which traverses the ocean floor by gravitational creep, ultimately plunging into secondary decompression cracks, emulating subduction. Much of the evidence presented in support of plate tectonics supports whole-earth decompression dynamics, but without necessitating mantle convection/circulation or basalt recycling. Moreover, unlike in earth expansion theory, the timescale for earth decompression is not constrained to the last 200 million years, the maximum age of the current ocean floor.
