Match List I with List II and select the correct answer using the code given below the Lists : List-I (Land from of peninsular India A. Marwarupland B. Bundelkhand C. Meghalaya upland D. Maharashtra plateau List-II (Predominat rock) 1. Quartzites Shalea, Schists 2. Sandstone Shale, upland Limestone 3. Granite and Gneiss 4. Basalt Code: A B C D
Explanation
The geological composition of Peninsular India varies across its distinct uplands. The Marwar Upland (Eastern Rajasthan) is primarily composed of sandstone, shale, and limestone from the Vindhyan period. The Bundelkhand Upland is characterized by the ancient Bundelkhand Gneiss, which is a coarse-grained gneiss resembling granite and is frequently criss-crossed by quartz veins [1]. The Meghalaya Upland (Shillong Plateau) contains ancient crystalline rocks including quartzites, shales, and schists, often associated with the Dharwar system and Archaean basement complex. Finally, the Maharashtra Plateau is part of the Deccan Traps, formed by the outpouring of basaltic lava during the Cretaceous-Eocene period [1]. Matching these gives the sequence A-2, B-3, C-1, D-4, which corresponds to Option 1.
