Which part of India has the Kalakot tertiary coal field ?
- A.Brahmaputra river basin of Assam
- B.Damodar river basin of Jharkhand and West Bengal
- C.Himalayan mountain region
- D.Cardamom hills in Kerala
Correct answer
Explanation
The correct answer is C, Himalayan mountain region. Kalakot lies in the Reasi district of Jammu and Kashmir, in the foothills of the Himalaya.
India's coal is of two ages. About 98 per cent is Gondwana coal, around 250 million years old, found in river valleys of the peninsula such as the Damodar, Mahanadi, Son and Godavari. The rest is younger Tertiary coal, about 15 to 60 million years old, which is found mainly in the north-east (Assam, Meghalaya, Arunachal Pradesh and Nagaland) and in the Himalayan belt of Jammu and Kashmir, where Kalakot, Metka and Mahogala are the known fields.
A is wrong because Assam's Tertiary coal fields, such as Makum, lie in the Upper Assam hills, and Kalakot is not among them.
B is wrong because the Damodar basin fields, such as Jharia and Raniganj, are Gondwana coal fields.
D is wrong because the Cardamom hills of Kerala have no coal field.
Exam tip: Gondwana coal lies in peninsular valleys; Tertiary coal is found in the north-east and in Jammu and Kashmir (Kalakot).
