Previous Year Question
Which of the following pairs is correctly matched?
Minerals — Producing Areas
Copper — Arizona
Coal — Carajas
Iron Ore — Rastanura
Petroleum — Donbas
Correct Answer: A
Detailed Solution
Arizona is an extremely important copper-producing region of the United States. According to the U.S. Geological Survey, Arizona is the leading copper-producing state in the United States and contains major porphyry copper deposits. Even in recent years, a very large share of U.S. copper production has continued to come from Arizona.
Carajas–Coal is not correct. The Carajás Mineral Province of Brazil is one of the world's major iron-ore regions. Giant high-grade iron ore deposits such as Serra Norte and Serra Sul occur here; therefore, Carajás is principally associated with Iron Ore, not Coal.
Iron Ore–Rastanura is also incorrect. The English paper prints the name as “Rastanura”; geographically, the reference is to Ras Tanura. Ras Tanura in Saudi Arabia is a major petroleum refining and oil-terminal centre. Saudi Aramco's refinery there began operations in 1945; it is not an iron-ore producing area.
Petroleum–Donbas is also incorrect. The Donbas/Donets Basin has historically been a major coal-producing region. According to the U.S. EIA, a large proportion of Ukraine's coal reserves occurs in the Donbas-Donets Basin.
