#anti-isostatic

• Anti-isostatic — Countering, opposing, or disrupting the isostatic equilibrium of the Earth's crust; a tectonic phenomenon, magma movement, or gravitational imbalance that prevents the restoration of the hydrostatic floating state of the lithosphere on the asthenosphere. In a structural sense, it describes density anomalies or endogenous forces that generate massive stresses in mountainous regions or oceanic basins.
