{a) Sea cliffs on eastern coast line both north and south of. 

 Stansbury. 



(b) Small local occurrence in sea cliff west of Troubridge 



Hill, on south coast. 



(c) At Corney Point a three feet bed of Eocene limestone, 



in a very limited lateral extension, rests immediately 

 upon the metamorphic rocks. 



{d) At Point Turton, in Hardwicke Bay, occurs the most 

 important exposure of these beds in the district. 



(e) At Brutus Castle, Sec. No. 74, Hund. of Parawurlie, an. 

 inland cliff of Eocene can be seen not far from -^he 

 coast. 



(/") Hund. of Coonarie, Sec. Xo. 205, about three miles south- 

 east from Warooka and one mile east of Piesey Trig., 

 a considerable exposure of limestone of this age occu- 

 pies the slope of the hill near fhe public road. 



{g) Inland cliff about four or five miles from coast at Sturt 

 Bay. 



(A) Another exposure in the same Hundred, in or near Sec- 

 tion 75, about one mile from the coast. 



(i) Hundred of Melville, Sec. No. 254, near seven road ends, 

 between Yorketown and Edithburg. 



{j) In the same Hundred, a well-sinking in Section No. 

 265 E., proved the Eocene limestone at a depth of 

 60 ft. from the surface. In another sinking, on the 

 adjoining section. No. 264, and situated on the other 

 side ot the public road, the limestone was also met 

 with at about the same depth. 



As the outcrops above mentioned have but a limited local 

 extension, and the limestone is but very rarely met with in 

 sinking wells, it is evident that the Eocene beds in the dis- 

 trict must be regarded as widely scattered outliers that are 

 the remnants of what originally was a continuous formation. 



Removal of Material by Chemical Solution. 



The removal of the Eocene limestone from so large an, area 

 is a notable fact, and one that cannot b6 accounted for on 

 the assumption of sub-cerial erosion, for no such mechanical 

 agent of transportation as running water exists throughout the 

 district to-day, nor is there any indication in the physical 

 contour of the ground, or in the alluvial deposits, that it has 

 operated to any great extent in post Eocene times. AlF 

 the facts that are available seem to point to chemical solution 

 as the probable agent of removal. 



That extensive chemical change and reconstruction have 

 been effected over the area in question is apparent from many 

 distinct lines of proof. At Point Turton and elsewhere the
