1.— THE PERMO-CAEBONIFEROUS GLACIAL BEDS AT 

 WYNYARD, NEAR TABLE CAPE, TASMANIA. 



By Professor T. W. EDGE WORTH DAVID [Gen. Sec. of Glacial 

 Committees). 



[With Plate.] 



Througli tlie kindness of Mr. W. H. Twelvetrees, F.G.S., Govern- 

 ment Geologist of Tasmania, the author was furnished with copies of 

 the official reports by Mr. Twelvetrees and his late assistant, Mr. G. A. 

 Waller, together with a series of local maps relating to the remarkable 

 glacial beds of the above locality. These strata were termed by the 

 late Government Geologist, Mr. A. Montgomery, the Wynyard forma- 

 tion. Later they were referred to specially in a report by Mr. G. A. 

 Waller " On the Coal of the Inglis and Arthur River District, near 

 Table Cape." A very interesting section is also furnished in this report, 

 which makes it clear that the Wynyard beds are at the base of the 

 Permo-Carboniferous system in that locality. 



On the occasion of the meeting of the Australasian Association 

 for the Advancement of Science, at Hobart, in 1902, Mr. A. E. Kitson, 

 late of the Geological Survey of Victoria, now Geologist to Nigeria, 

 made the important discovery of undoubted ice-scratched boulders in 

 these Wynyard beds at a point about three miles E.S.E. of the town 

 of Wynyard. At the close of the Association meeting a geological 

 excursion was led to the spot by Messrs. Waller, Kitson, and others, 

 and a number of excellent striated boulders were obtained. Since 

 then Mr. Twelvetrees has visited the area, and made a special 

 report on the occurrence of coal and kerosine shale at Preolenna. 

 His report entirely confirms that of Mr. Waller in the stratigraphical 

 horizon assigned to the Wynyard formation. It is clear that its posi- 

 tion is at the base of the Permo-Carboniferous system, and below the 

 fresh-water Coal Measures of Preolenna. These Coal Measures, which 

 are interstratified between two marine Permo-Carboniferous series, are 

 almost certainly the equivalents of the Greta Coal Measures of New 

 South Wales. The result of the author's visit to the locality last 

 April, together with notes kindly supplied by Mr. Twelvetrees, are 

 given in the accompanying short report. 



Immediately to the south of the entrance to the Inglis River at 

 Wynyard, and for three miles towards Burnie, there are magnificent 

 flat sections in the coast platform of marine erosion showing the glacial 

 beds. These beds, called by Mr. A. Montgomery (the late Government 

 Geologist of Tasmania) the Wynyard Formation, extend also N.N.W. 

 from the Inglis River for a distance of about two miles towards Table 

 Cape. 



At Freestone Cove, near Table Cape, the top of the glacial beds 

 is about the level of half-tide, or mean sea-level. It is there capped
