Бретонт.— Benmore Coal Area of the Malvern Hills. 625 
well-defined series of subparallel faults may be inferred. These are as 
ж» (вее ша 
) The faulted « area where occurs the Cordy Flat Coalfield, now being 
dew at Steventon. The fault-line runs along the northern flank of the 
Cairn Range, and continues in a south-west direction along the northern 
side of Mount Mise 
(2.) The area about Rockwood Station, whose sce is determined by a 
fault which follows up the eastern side of the eastern bran ch of the Hororata 
River towards Phillips Saddle, and may a continued spi ab h since 
small patches of coal-measures occur on the north-eastern flank of Rocky 
Peak, and the form of the saddle suggests a etructural origin. 
(3. Upper Selwyn basin, which is faulted down along the north 
side of the Flagpole Range on a line running past High Peak. A splinter 
of this fault payed occurs a little to the north-west, and this continues 
to the north-east into the basin of the Hawkins River behind Dalethorpe, 
where the ected stripped surface indicates a former extension of the 
coal-measures into the upper basin of that stream, the only visible sur- 
viving remnant being a small patch on a tributary coming in from the north 
just west of the trig. marked 2725. The stripped surface of the Hawkins 
area is a continuation of that of the Upper Selwyn area, since there is no 
break between the basins of the two streams, and the нее Selwyn River 
m at one time have flowed into the Hawkins. 
The line of fault runs in close to the small patch of po tear coal-measures 
wns behind the Woodstock Station, the pce and makes gerd beds 
containing Conchothyra and Trigonia, and other shells exposed in the bed 
of the river near Otarama being a part of the beds which have been faulted 
own.. 
These M coal-measures have been covered up by the aggrad- 
ing gravels brought down by the Kowai and its tributaries. An extension 
of this fault-line probably ^x um after a slight turn along the south-eastern 
flank o e marked break in the topography all 
along the range, and the s similarity i in the form of successive ridges as they 
abut against the sides of Benmore, are to be explained in this way, 
although there hardly appears to be sufficient evidence on which to base a 
positive statement of the existence of a fault. Its direction is nearly 
parallel with what may be regarded as definite fault-lines occurring in other 
parts of the area. 
suggested fault would necessitate a change of throw from the 
Bergan to the south-east side of the fault, a reversal of displacement 
amounting to hundreds, if not to thousands, of feet. Such a change would 
be remarkable in a short distance. For these reasons the continuance of 
the Kowai ses along the south-eastern flank of the Benmore "eee is 
à € ful.
