Abstract

Summary

A guiding dictum followed by field geologists is ‘.’ Problems arise when in situ, fresh and ‘dependable’ rock exposures are not available for requisite interpolation and/or extrapolation. Geophysicists have the key to sort out those problems. The mutual complementary and supplementary relations existing between the two siblings of Geosciences are remarkable.

The relentless efforts of innumerable Himalayan geoscientists from all over the globe through almost the last two centuries have generated data which, with sound geological reasoning, can now be fitted together nicely to solve the ‘jigsaw puzzle’ of the big picture of Himalayan tectonic-geodynamic evolution. The present work does this, and highlights the profound need for systematic and collaborative geophysical studies, particularly seismic sounding, along several well-chosen transects cutting across the Himalayas, for necessary authentication.
