Which one of the following minerals is not found in Uttar Pradesh?

The answer is B) Mica. Among the options, Mica is the one not recognised as a commercially significant mineral of Uttar Pradesh. Its major deposits lie in the Chota Nagpur belt (Jharkhand, Bihar), Andhra Pradesh and Rajasthan, and UP's Gangetic alluvium has no mica belt.

The other options are found in the state. Bauxite is mined in Lalitpur and Mahoba in the Bundelkhand region. Limestone is extracted from Sonbhadra, Mirzapur and Lalitpur, and it is the base for the cement and chemical industries. Gypsum occurs in parts of the state, though its production is small compared with Rajasthan and Gujarat, so verify the district-wise data against the latest Geological Survey reports before relying on it.

Core concept: mineral geography and the link between geology and industry. This connects to the Bundelkhand and Vindhyan geology in the syllabus and to Mains questions on resource-based industrialisation in eastern UP.

Trap: aspirants often assume every mineral in the Vindhyan belt is present in UP. Mica is tied to the peninsular crystalline belts, not the Vindhyan-Gangetic zone.
