The formation of mountain range curvature by gravitational spreading

摘要: This paper presents a mechanism by which mountain ranges can form curved range-fronts. Gravitational spreading of that have been thrust onto rigid lowlands will result in the formation curvature, provided enough gravity-driven flow occurs to dominate shape topography. Whether this operate during lifetime given range depends upon viscosity range, square along-strike length and cube elevation range. The curvature southern edge Tibetan Plateau is consistent with gravitational similar previously estimated using other, independent, methods. low young age Zagros mountains mean large-scale has not had time develop. short extent possibly Sulaiman Ranges Pakistan may allowed their distinctive arcuate shape. range-front plays an important role controlling tectonic evolution interiors ranges, arc-parallel extension becoming progressively more as develops.
