ORISSA.
XXIII. Talchir.*
The
Talchir coal field is situated in the valley of the Brahmani, which may
be regarded as a tributary of the Mahanadi, since it anastomoses with
it in the con-joined deltas. The field is really the south-eastern
extension of the last-mentioned area, the separation being
inconsiderable. The area is about 700 square miles in extent The groups
represented are similar to those found in the last area, and have the
following estimated thicknesses :—

The Talchir group received its name from this locality, where it was first discriminated.
The
coal is of inferior quality, one large seam being similar in character,
being largely made up of carÂbonaceous shale, to that described above
in Hingir.
The
demand for coal in Orissa is too limited to render it probable that
under present conditions of communication the field will ever be of
much value.
Further
to the south-east, near the town of Cuttack, there is an area of
sandstones and conglomerates in which fossil plants of the Rajmahal
type occur.
