A. Vindhyan Supergroup✓ Correct Answer
B. Chail and Jutogh Series
C. Deccan Trap Basalts
D. Siwalik Molasse
💡 Solution & Explanation
The Lesser Himalayan zone in Himachal Pradesh is characterized by metamorphic formations known as the Chail and Jutogh series, which consist of ancient slates, phyllites, schists, and quartzites thrust over younger rocks along tectonic thrust faults. The Siwalik molasse forms the southernmost tertiary belt. Detailed stratigraphic knowledge of the outer and lesser Himalayas helps in assessing slope stability and landslide hazards.
