Himalayan Elevation-Somnolence to Hyperactivity

This short note attempts to illustrate the efficacy of multiple-_Probe investigations in solving complex geological problems. The Cenozoic is the era of Alpine-Himalayan orogeny and the uplift pattern is one of long somnolence followed by brief hyperactivity. Nowhere else has this pattern been studied in greater detail than perhaps in the Himalaya. Classical stratigraphy, fossil records of flora and fauna, and sedimentologic, paleoclimatic and geomorphologic data offer sample evidence in this direction. Modern techniques of radiometric geochronology of the Himalayan crystallines also support this contention.
