Glacial Beds at Wynyard, Tasmania. 33 



It is interesting to note that these predictions, first by Mr. 

 Stephens, and later by Mr. Montgomery, have been fully verified, 

 as the upper beds of the series to which the glacial deposits 

 belong, and containing seams of cannel coal, as pointed out^ 

 by Mr. Geo. A. Waller, have been discovered some little distance 

 inland from Wynyard, in the basin of the Inglis River. 



At the mouth of the Inglis, east of the breakwater, till may be 

 seen at low tide, and here appears about horizontal. About 

 three-quarters of a mile further east shaly mudstones, very much 

 jointed, show in the beach floor. They dip about N. 70° W. at 11°. 

 The successively superimposed beds show beautiful serrated edges 

 at right angles to the shore line, where the ever restless waves 

 have furrowed them. There is also a pretty, wavy appearance 

 along the different beds, and they are jointed to a great extent. 



Traced further eastwards along the shore hard, tough con- 

 glomerates, consisting principally of normal and altered sedi- 

 mentary rocks, are visible on the beach just to the west of 

 Seabrook Creek, with an overlying bed, seen only in places, of an 

 exceedingly hard, fine, dense, bluish-grey sandstone, greatly 

 resembling many sandstones in the Victorian Mesozoic Coal 

 Measures, even to their characteristic pitted weathering. 



To the east of the point of basalt I'unning into the sea on the 

 eastern side of this creek blocks of similar conglomerate can also 

 be seen. They contain veins of calcite up to 6 inches in 

 thickness. 



The glacial beds were not observed east of this place, the shore 

 line as far as Burnie, wherever examined, being occupied by 

 recent deposits, by basalt, or by highly inclined, folded and 

 contorted siliceous slates, sandstones, and quartz schists, having a 

 general strike between N.N.E. and N.E. These are regarded by 

 Mr. Stephens as possibly forming the base of the Lower Silurian 

 (Ordovician) series, or even of being still older in age, while Mr. 

 Montgomery speaks of them as of Cambro-Silurian age. 



They contain multitudes of quartz veins and small reefs, 

 especially near Burnie. A number of anticlines and synclines 

 can also be observed at low tide, the former especially being 

 splendid examples, showing beautifully the rounded curves of the 

 strata.
