Dawson, 1874. 55

hard, shaly, olive green in colour. Showing evident horizontal stratification, very well marked by whitish lines similar to those seen in same beds in creek W. of Woody Mt Astron Stn.

On following the creek Northwards from the line more than a mile the beds are seen suddenly to take a bend upwards & inferior beds with sanstone layers come to the top & form the banks.

The section appeared to be quite clear & there was no reason to suspect the existence of a fault. The beds thus exposed consist mainly of greyish & yellowish sandy clays with however several horizons of sandstone & ironstone & beds of.Carbonaceous Shale thinly cleavable, some of which might be called impure lignite.

It does not appear whether these beds are altogether inferior to the Long R. Shales, or whether they meerly [sic] form an important intercallations in them. The former seems most probable & in that case the Long R. aspect cannot be confined strictly to any horizon of the Sombre Clays as it was previously observed to be common near their upper part.

The strike of the beds is N 270E & their dip S.Eastward at angles of front about 450 to 300. But for the discovery of 'what appear to be authentic oyster remains in one of the beds superior to the Carbonaceous Shales. would have been tempted to put the beds down as Lignite Tertiary & look very closely for a fault or dislocation. It is evident that such carbonaceous clays as those here represented might at a short distance coalesce into a bed or beds of lignite if good quality. The Carb. shales exactly resemble many of those seen in indubitable Lig. tert. even to the occurrence in them of amber flag like leaf markings &c. None of the vegetable impressions however seemed capable of identification.

Made a paced section of the beds across the strike, coming down the valley or S.Eastward, & consequently passing from older to newer beds.
