DETAILED DESCRIPTIONS OF THE RESPECTIVE COALFIELDS. 
31 
few thin bands of coal were found by F. H. Smith^ in a railway tunnel 
to the south of Kayeng, but they are only a few inches each in 
thickness, and of no economic importance. 
From time to time samples have been sent to the Geological 
Survey offices, but they liavo invariably proved to be lignites and 
jetty coals fiom the nests which so commonly occur in the younger 
Tertiaries. 
(vi). Baluchistan. 
Thai Chotiali, etc. — Coal of good quality was discovered in the 
Chamarlang valley in the Luni Pathan country, about 75 miles 
west of Dera Ghazi Khan, by Sir R. Sandeman. In 1874 Ball ^ 
visited the locality and found that the principal coal-seam is only 9 
inches thick, and that there are numerous thinner bands. He 
pronounced the measures to be of Lower Tertiary age, and gave 
reasons for doubting that a workable coal-seam would be found. 
Coal of the same age was discovered by officers ^ of the 
Geological Survey in 1891 during the course of the detailed mapping 
of Thai Chotiali and the Mari country. Near Duki, about 40 miles 
west of Chamarlang, several seams occur but the thickest is not 
more than 14 inches. In the Mari country near Khatan, well- 
known for its petroleum springs, a thin band of impure coal was 
found. 
Khosf, Shariyh, etc. — In the hills flanking the frontier section of 
the Sind-Pishin Railway at a height of about 4,000 feet above sea- 
level coal of Tertiary (eocene) age is found over a considerable area 
of country. The rocks, as a rule, dip at high angles towards 
the axis of the range and are much disturbed by faults and 
landslips. 
In 1880 Griesbach-^ and in 1881 Blanford^^ visited the 
locality and reported iinfavourably of the then known outcrops 
of coal. The latter describes a section near Sharigh in which not 
less than thirty coal-seams are to be found within a vertical thick- 
ness of 370 feet of strata. He states, however, that most of them
