Q1. [1] medium thorough-understanding
[mcq] Which of the following correctly describes the significance of the Koderma–Gaya–Hazaribagh belt for mica production in India? (A) It is located in the alluvial plains of the Ganga, where mica accumulates as placer deposits carried by rivers from the Himalayas. (B) It lies along the northern fringe of the Chota Nagpur plateau in Jharkhand and is the leading mica-producing region in the country. (C) It falls within the Deccan Trap region of Maharashtra, where mica crystallises from volcanic lava flows. (D) It is part of the Rajasthan desert belt where mica forms as an evaporite mineral in dry lake beds.
  1. A Jharkhand has ideal coastal conditions that allow mica to form through evaporation of seawater.
  2. B The northern edge of the Chota Nagpur plateau, which falls in Jharkhand, hosts the Koderma–Gaya–Hazaribagh belt, the country's leading mica-producing region.
  3. C Jharkhand's alluvial plains deposit mica as placer deposits along river valleys.
  4. D Mica is a by-product extracted from bauxite refining in the Amarkantak plateau.

Model Answer

Answer: (B)

The northern edge of the Chota Nagpur plateau, which falls in Jharkhand, hosts the Koderma–Gaya–Hazaribagh belt, the country's leading mica-producing region.

Explanation

The textbook (Chapter 5, Non-Metallic Minerals) directly states: "Mica deposits are found in the northern edge of the Chota Nagpur plateau. Koderma Gaya–Hazaribagh belt of Jharkhand is the leading producer." All other options introduce incorrect locations or formation processes (alluvial plains, Deccan Trap, evaporite, bauxite refining) that contradict the source. In MCQs, pick the option that matches the textbook statement word-for-word or in meaning.
