XX, LUKANPUR.*
This
field lies to the south of the Bisrampur area, from which it is
separated by a fault and a belt of Talchirs, with inliers of
metamorphic and sub-meta-morphic rocks. Its total extent has not yet
been ascertained, but it is probable that it is continuous with a large
area of coal-measure rocks, believed to exist far to the westward.
Several
seams of coal have been discovered, one of which is five-and-a-half
feet thick and contains good coal. The rocks belong to the Barakar and
Talchir groups.
XXI. RAMPUR.f
This
area adjoins the last on the north, and it is probable is more or less
connected with that which follows, but it is partly situated in a
different catchÂment area near the sources of the Rer river, a
tributary of the Sone, while the field about to be described is wholly
within the limits of the Mahanadi basin. The rocks of this portion
consist of Mahadevas, Barakars, and Talchirs. No good coal has been
observed yet. The most remarkable seam is situate at the base of the
massive square block of Mahadevas known as the Ramgurh Hill.J Above it
issues a perennial fountain of water, which, with some other
peculiarities, have caused the spot to be regarded as one of great
sanctity by the natives.
