Mesozoic Rocks,

or Cape Otway districts, and tlie dip is nearly constant in a general 
south-easterly direction at an angle of from 7° to 25°. (Figs. 29, 30, 
and 31.) In the course of explora- 
tion of theGippsland Mesozoic areas, 
I found that the south-easterly dip 
appeared to prevail from the extreme 
northern edge of the series between 
the Tjrers and Rintoul’s Creek to the 
south-easternmost exposure of the 
Mesozoic rocks in Brutlien Creek, 
on the fall towards the coast. This 
would indicate the very great thick- 
ness of over 20,000 feet, assuming 
an average rate of inclination not 
exceeding 10°; but it is possible that 
undulations in the strata may occur, 
or that the beds become more hori- 
zontal between the points where I 
was able to take the dips, thus neces- 
sitating a reduction in the estimate. 
Along the Narracan Creek, south 
from Moe, the strata are sometimes 
nearly horizontal. 
Coal-seams occur in a number 
of different localities. These will, 
however, be specially noticed in a subsequent chapter.
