Official UPSC Answer KeyUPSC Prelims 2006 • Science and Technology

Correct Answer: Option (B) — 1, 2 and 3 only

Concept & Option Breakdown

Standard Reference Verified

Statements 1, 2, and 3 are correct: The coastal placer beach sand deposits of Kerala (e.g., Chavara deposit) are world-renowned for heavy mineral suites including ilmenite, rutile, zircon, monazite, sillimanite, and garnet.

Statement 4 is incorrect: Tungsten (found in minerals like wolframite and scheelite) is primarily associated with quartz veins in granitic intrusions (e.g., Degana in Rajasthan), and is not found as a constituent of Kerala's beach sands.

Elimination Heuristic & Exam Approach

Tungsten is a heavy metal associated with hard rock/skarn vein deposits, not coastal heavy placer sands.
