Alternative ... WebAllowing for the impact of weathering of high 87 Sr/ 86 Sr rocks exposed by the Himalayan orogeny, the riverine Sr flux must have increased by about 60 % over this time period. Alternative explanations, that the change in seawater 87 Sr/ 86 Sr ratios reflect only the changing 87 Sr/ 86 Sr ratio of the riverine input lead to an equivalent conclusion.

The Himalayan Collisional Orogeny: A Metamorphic Perspective

During Late Precambrian and the Palaeozoic, the Indian subcontinent, bounded to the north by the Cimmerian Superterranes, was part of Gondwana and was separated from Eurasia by the Paleo-Tethys Ocean (Fig. 1). During that period, the northern part of India was affected by a late phase of the Pan-African … Visualizza altro The geology of the Himalayas is a record of the most dramatic and visible creations of the immense mountain range formed by plate tectonic forces and sculpted by weathering and erosion. The Himalayas, which stretch … Visualizza altro One of the most striking aspects of the Himalayan orogen is the lateral continuity of its major tectonic elements.
