Indian building stones: Black marble (commonly used as a decorative and facing stone) is generally found in which of the following districts?

Introduction / Context:
Knowledge of the geographical sources of construction stones is important for civil engineers, architects, and contractors because it affects availability, cost, and material properties. This question asks about the common Indian source district for black marble, a popular decorative stone.

Given Data / Assumptions:

• The term “black marble” refers to a decorative carbonate rock marketed as marble.
• Options list well-known Indian districts associated with stone quarrying.

Concept / Approach:
Different districts in India are famous for distinct stones: Makrana (white marble), Jodhpur (sandstone), Jaisalmer (yellow limestone), etc. Black marble occurrences are commonly associated with belts extending into Madhya Pradesh, with Jabalpur frequently cited in traditional MCQ references as a source of black marble varieties supplied for architectural works.

Step-by-Step Solution:

Verification / Alternative check:
Traditional building materials guides and question banks routinely pair black marble with Jabalpur, while Rajasthan districts listed tend to be associated with other colors/types of stones more prominently.

Why Other Options Are Wrong:

• Jodhpur/Jaisalmer/Jaipur: renowned for sandstones and yellow limestones; not the standard reference for black marble in exam contexts.
• Pune: not a typical source district cited for black marble in basic construction MCQs.

Common Pitfalls:

• Confusing commercial trade names with geological sources.
• Associating “Rajasthan” automatically with all marble colors without checking district–stone matches.

Final Answer:
Jabalpur
