Abstract

In the Indian Himalaya, the Cambrian sequences are exposed in the Lesser and Tethyan Himalayan zones (LHZ and THZ). In the LHZ, the Cambrian biozonation is available at four stratigraphic intervals, i.e., at ~542- 535 Ma, ~524-513 Ma, ~516 Ma, and ~512 Ma. In the THZ, the Cambrian biozonation exists broadly at two stratigraphic intervals, i.e., ~514-505 Ma (in the Spiti region and partially in the Kashmir region) and ~505- 498 Ma (in the Zanskar region and partially in the Kashmir region). The Indian Cambrian faunal elements share Gondwanan and peri-gondwanan affinities. The depositional environments of the Cambrian sediments of THZ and LHZ show a wide array of settings.
