Stabilization of Crustal Subsidence in Geosynclinal Terranes by Phase Transition at M
Isostatic calculations indicate that a mechanism of geosynclinal subsidence based on a phase transformation at the M discontinuity possesses an inherent stability that will tend to maintain the upper surface of sediments near sea level regardless of fluctuations in the rate of geoisotherm depression or in the rate of sedimentation. This effect may help in the understanding of sedimentation in geosynclinal and stable-shelf terrane.
