PROCEEDINGS OF SECTION 0. 183 



Similar marine beds containing similar fossils have been recorded* 

 from the Government quarries at Maryborough, where the beds dip 7° 

 N, 35° E. ; from the head of the Isis River, 6 miles due W. of Howard, 

 the centre of the Burrum coal-field, and dipping 30°-45° E., dir. 40° N., 

 from an area 32 miles N.W. of Bundaberg, and 10 miles' S. of Rosedale 

 gtation, dipping 12° in a N.E. direction. 



Mr. Dunstanf records further outcrops of these beds near the 

 Takura railway station and at Nikenbah, 5 miles N.E. of the Takura 

 quarry. 



In the calcareous sandstones containing shallow-water marine 

 fossils, in the neighbourhood of North Blufi, Woody Island, one finds 

 occasional fragments of wood which has been largely converted into 

 iron-oxide. In some cases the wood forms the centre of an ironstone 

 concretion . 



Freshwater Series. — Conformably overlying the marine beds, and 

 also in some cases interbedded with them, are beds of freshwater 

 origin containing abundant plant remains, and, as far as could be seen, 

 devoid of marine fossils. 



These beds consist of shales and sandstones for the most part. 

 In places the carbonaceous remains are so abundant as to give rise to 

 a coaly shale, and on the shore-line about a half-mile south of Datum 

 Point there outcrop two seams of brown shaly coal, each of which is 

 about 2 feet wide and separated by about 6 feet of carbonaceous shale. 



Beds of white argillaceous sandstone, with occasional ironstone 

 concretions are characteristic of the freshwater series on the S.W. side 

 of the island, and they outcrop along the shore-line in the 

 neighbourhood of the cable-house where the telephone cable from 

 the mainland touches the island. These beds of sandstone seem 

 quite devoid of plant remains. 



The freshwater beds are found to have a general strike of 40°-45° 

 W. of N. 



At Datum Point they dip in a S.W. direction at an angle of 80**, 

 whereas at the southern end of the island the dip is only about 20°. 



The dip of both freshwater and marine beds is thus seen to be 

 much steeper at the northern end of Woody Island than anywhere 

 else in the area. 



The seams of brown coaly shale were not found at the southern 

 end of the island, but this is not surprising as the shore line where one 

 would expect to find them is thickly covered with beach material, 

 and there are no exposures at all of rocks in situ in the immediate 

 locality.
