COAL AND PETROLEUM. 67 



where else along the eastern side of the hills we have a steep scarp 

 of the westerly dipping beds. Where exposed the beds on the east 

 side have a dip of about 8o° to the east, and the dip of the rocks on 

 the westerly side of the anticlinal arch is fairly constant at about 35 

 all along the hills with the exception of the extreme ends. At their 

 northern end the hills end quite abruptly in a vertical cliff which 

 shows a section across the anticline, but at the southern end they 

 sink more gradually but still somewhat rapidly underneath the 

 alluvium which surrounds them. 



The upper miocene beds which are exposed in these hills consist 

 of thick massive beds of sandstone with layers

or shale, and as at Yenangyaung but unlike the 



beds at Singu and Yenangyat the sandstones predominate. The 



thickness of beds exposed I measured as between 2,000 and 2,500 



feet. The sandstones which occur in thick massive beds are greyish, 



yellowish and brownish in colour and are mostly very fine-grained ; 



the shales are greenish and greyish in colour and in one band near 



the base there were streaks of coal. In the 

 shaie re band.° f COal *" * centre of the range of hills towards the base 



of the beds exposed, the shales have a distinct 

 bluish-tinge, and this may perhaps indicate that the Prome beds are 

 not very deep below the surface. I did not see any lower miocene 



beds exposed or find any traces of petroleum

or hear of any being noticed by the villagers 

 at other times, but it is possible that oil-bearing rocks may be 

 present at no very great distance from the surface. As there are 

 no means of knowing the thickness of the upper miocene beds in 

 this part of the country or how great a thickness at the top is 

 concealed beneath the alluvium of the surrounding country, it is 

 impossible to make even an approximate guess at the depth 

 of the Prome beds or the likelihood of their being oil bearing, but 

 when other sources of supply are exhausted

 ing on their eastern side with some hopes of 

 success.
