Lignites are met with at Smyrna and Lebanon.
The coal-fields of Hindoostan are small but numerous, being found in all
parts of the peninsula. There is an important coal-field at Raniganj,
near the Hooghly, 140 miles north of Calcutta. It has an area of 500
square miles. In the Raniganj district there are occasional seams 20 feet
to 80 feet in thickness, but the coals are of somewhat inferior quality.
The best quality amongst Indian coals has come from a small coal-field of
about 11 square miles in extent, situated at Kurhurbali on the East
Indian Railway. Other coal-fields are found at Jherria and on the Sone
River, in Bengal, and at Mopani on the Nerbudda. Much is expected in
future from the large coal-field of the Wardha and Chanda districts, in
the Central Provinces, the coal of which may eventually prove to be of
Permian age.
The coal-deposits of China are undoubtedly of tremendous extent, although
from want of exploration it is difficult to form any satisfactory
estimate of them. Near Pekin there are beds of coal 95 feet thick, which
afford ample provision for the needs of the city. In the mountainous
districts of western China the area over which carboniferous strata are
exposed has been estimated at 100,000 square miles. The coal-measures
extend westward to the Mongolian frontier, where coal-seams 30 feet thick
are known to lie in horizontal plane for 200 miles. Most of the Chinese
coal-deposits are rendered of small value, either owing to the
mountainous nature of the valleys in which they outcrop, or to their
inaccessibility from the sea.
