Comparison with other Areas. 
The petroliferous rocks of Assam and Burma are quite 
different in character from those of the Punjab. In those 
regions the oil is distributed through a vast thickness of sand- 
stones and shales which give little or no indication of any 
change in the conditions under which they were deposited. Oil 
seepages occur at various horizons throughout some 20,000 feet 
of such rocks in Burma, and no geologist has as yet even 
suggested that any horizon or horizons should be regarded as 
the primary source-rock of the oil. 
A very striking parallel can be drawn between the oil 
occurrences of India and those of the Carpathian oil-fields. In 
Galicia and northern Rumania the oil occurs in the “ Flysch,” 
* monotonous series of sandstones, shales, and conglomerates, 
which must be similar in lithology to the oil-bearing Pegu rocks . 
Pascoe hag put forward an exactly similar hypothesis to explain 
the relation between oil and coal occurrences in Burma? and 
Assam.3 
_~ he conditions in the central Rumanian fields are entirely 
different, Here the origin of the oil is attributed by Professor 
azec to the “Miocéne Salifére,” the final lagoon facies of 
the deposits laid down in the miocene Mediterranean Sea. The 
large productive fields, however, obtain their oil from Pliocene 
fresh -water deposits. These rocks are devoid of oil except
