Correct option is B
Large deposits of high-grade silica sandstones occur in Shankargarh (Allahabad) and Bargarh (Chitrakoot) districts. These have traditionally been the primary sources for the glass industry in North India.
Explanation:
● Silica sandstones from Shankargarh and Bargarh are valued for their high purity and suitability for glass manufacturing.
● These deposits are essential for producing high-quality glass products like sheets, bottles, and optical lenses.
● The sandstones are processed to extract silica, which is a key ingredient in the glass industry.
Information Booster:
● Uttar Pradesh has significant reserves of silica sandstones, contributing to India’s glass production capacity.
● Shankargarh is often referred to as the "Glass City" for its role in the glass industry.
● The extracted silica is also used in the manufacturing of ceramics and silicon-based products.
● The proximity to transportation networks ensures efficient supply to industries.
