NOTES ON THE GEOLOGY OF BOWNING, N.S.W. 

 By John Mitchell. 



(Plate XXL) 



The following notes bear more particular reference to the Geology 

 of the Parish of Bowning, and a small area eastward of it bounded 

 by Limestone Creek. Some general references will also be made 

 to the geological features of the country to the west of this area. 



The former area may for convenience be considered as consisting 

 of two divisions, one extending in an east and west direction from 

 Limestone Creek to a low ridge or boss of quartz porphyry about a 

 mile west of the Public School on the Great Southern Road, and 

 running in a generally N. and S. course, parallel with the strike 

 of the sedimentary rocks ; the other extending from this ridge 

 westward to the Black Range, or western boundary of the parish. 



Physical Features. — The Parish of Bowning forms a small portion 

 of the Southern Table Lands, and has an elevation above the sea 

 of from 1,800 ft. to 2,400 ft. The surface is of an undulating 

 character in the central and northern area, and decidedly rugged 

 in the southern. 



The most striking feature is Bowning Hill, which is a pyramid- 

 shaped mass rising abruptly to a height of from 600 to 700 ft. 

 above the immediate level on the eastern boundary line of the 

 parish. 



The principal valley forms the basin of Bowning Creek, and 

 follows the general strike of the rocks, having been formed chiefly 

 by the erosion of the exposed edges of the more fragile kinds. 



The porphyry ridge already referred to divides the parish into 

 two fairly equal parts, and separates the waters of Bowning and
