188 Geological formations of Tenasserim Provinces. 



strike in the schistose rocks, which form the terminating 

 point of the bank to the south. 



The rocks at this point consist of greenstone, gneiss, and 

 mica schists. Granite and quartz veins traverse the masses 

 of rock in all directions ; the former being generally in the 

 superior strata (greenstone), and the latter of various di- 

 mensions through the schistose rocks below. 



From the above point to the one at the river's mouth, 

 with the exception of a few granite boulders, all vestige of a 

 primitive formation is lost, the only rocks occurring besides 

 the above granite boulders, being of the conglomerate already 

 noticed, which is highly cellular and indurated on the surface, 

 but soft and more compact beneath. At the point from 

 which a reef extends, the primitive formation again shows 

 itself, but in such confused masses as to obliterate all trace 

 of regularity of form. The principal rock however, appears 

 to be greenstone, unaccompanied on its southern face by 

 any of the schistose forms. Into this quartz veins of various 

 dimensions and highly crystaline structure, have been thrust 

 in all directions ; completely enveloping the greenstone in some 

 parts ; at others, showing a vertical line for a short distance, 

 and then abruptly terminated, or moved out of its position 

 by intervening lines of quartz veins (quartz and mica). On 

 the northern face of this mass, the clay and mica slate appear, 

 the former being superior: both however having a direct 

 vertical strike, until covered by the rock forming the sea 

 face, which consists of clay slate in a decomposed state, 

 with scarcely any perceptible angle of inclination. 



The foregoing remarks are intended more as a rough note 

 of the geological features of the coast at this place, than a 

 systematic classification of the rocks described, as from the 

 almost imperceptible transition of the schistose rocks into 

 each other, it would require a more practical knowledge of 

 them, in various localities, than I possess, to render such a 

 classification perfect; sufficient however will be gained to
