Chromium (Cr) Ore Deposit of India || lecture 52 of Economic Geology

Описание: This Geology lecture explains Chromium (Cr) deposits of India, focusing on the geological, mineralogical, and industrial aspects of chromite (FeCr₂O₄) — the only ore of chromium.

In this video, we discuss:

Introduction to Chromite – properties, composition, and industrial relevance

Types of Chromite in India – High-grade, Ferriferous, Aluminous, Siliceous varieties

Cr/Fe Ratios and Mineralogical Features

Formation and Origin – magmatic segregation within ultrabasic rocks (peridotite, dunite, pyroxenite)

Types of Occurrence – Stratiform (Sukinda–Nuasahi, Sittampundi) and Podiform (Ladakh, Manipur)

State-wise Distribution – Odisha, Jharkhand, Tamil Nadu, Andhra Pradesh, Karnataka, Maharashtra, J&K, Manipur

Industrial and Economic Uses – Ferrochrome manufacture, stainless steel production, refractory materials, chemical uses

Odisha’s Sukinda and Nausahi belts remain India’s chromite heartlands, hosting most of the nation’s high-grade reserves.
