A gap of thirty-fire feet intervenes between the fossiliferous beds of Corner 
Creek and the next succeeding, which is seen in Brock s Creek, viz., a bed of blue 
crystalline limestone at least twelve feet in thickness. Thin sections of the limestone, 
examined under the microscope, revealed no traces of organic remains. 
About fifty yards further down Brock’s Creek, and probably about ten feet above 
the last-mentioned limestone, are fifteen feet of hard yellow sandstones, among which 
there are some greenish calcareous bands, and hard shales, dip)ping to S. at 25° to 30 . 
In this section I observed a curious case of contortion in the upper beds not continued 
into the lower beds (see Plate 53, fig. 3). This local contortion I ascribe to the unequal 
contraction of the purely sedimentary sandstones and shales and the partly chemically- 
formed calcareous sandstone. 
After a gap, probably not amounting to more than fifteen feet, the following 
section is seen in Donald’s Creek, dipping to S. at 20 : 
Blue shales with ironstone nodules, and impressions of Lepidodendron 
australe (McCoy), and thin hard limestone bands (upper beds at 
mouth of creek) 
Impure blue limestone ... 
Shales ... 
Hard sandstone 
Alternate bands of shale and fine, hard, calcareous sandstone, the sand- 
stone bands containing shells, and the shales plant-remains
