Which one of the following pairs (Deccan Trap Peculiarity) is not correctly matched ?

  1. Depth of middle trap – 1200 metres approximately
  2. Intertrappean beds – Fossils of sea plants and animals
  3. Depth of lower trap – 150 metres approximately
  4. Depth of upper trap – 450 metres approximately

Answer:

Option B: Intertrappean beds – Fossils of sea plants and animals

Detailed Solution:

The correct answer is “Intertrappean beds – Fossils of sea plants and animals”.

The Intertrappean Beds are a Late Cretaceous and early Paleogene geologic unit in India. These beds are found as interbeds between Deccan Traps layers, including the slightly older Lameta Formation. They consist a number of different subgroups and formations, and span the Cretaceous–Paleogene boundary.
