Abstract

The Precambrian-Cambrian transition has been extensively studied in the Krol Belt of Lesser Himalaya and in Higher and Tethys Himalayan part in Kashmir, Spiti-Zanskar, and Kumaun. A substantial amount of data that has now accumulated in both the areas of lithology, geochemistry, and biological changes is analysed and possible inferences are drawn.
