Between (6) and (c), at the head of Foilminnaun, is a strike- 
fault, the direction of which is marked by a layer of slickensided 
quartz about 12 inches thick. This fault determines the western 
limit of the inlet. 
A(7). This band of calcareous flags and slates occupies the 
northern side of the first cove south of Redcliff Cove. The beds dip 
34° south 30° east at the base of the point, and 25° south 20° 
east farther along it. _From them we obtained :— 
Atrypa reticuiaris (Linn.). Pterinea (2) subfalcata, Conr. 
Chonetes striatella, Dalm. Crinoid-stems. 
. Spirifer sp. 
A(8). This is an extremely coarse ashy conglomerate, the frag- 
ments of which range from less than an inch to more than 2 feet in 
length. They consist of rhyolite, or of rhyolitic ash. This bed can 
be followed inland to the north-north-east, and is met with in the 
neighbourhood of the Stone Cross marked in the 6-inch Ordnance- 
Survey map. 
A (9). This greenstone occupies ae south-eastern side of Redcliff 
Cove, and judging from loose fragments found abundantly inland, it 
occurs also in the neighbourhood of the Stone Cross. Usually it 
follows the bedding, but is seen here and there to cut across it. 
Most of the greenstone is extremely weathered. 
A (11) is a prominent band of compact purple rhyolite, forming a 
tongue that juts out into Redcliff Cove, and it is to this rock that 
the cove no doubt owes its name. Xenoliths of rhyolite are included 
in the rock, especially near the upper surface, and cause some 
hand-specimens to have the appearance of ashes. : 
A (13), which extends northward from the point west of Redcliff 
Cove, is a medium-grained ash, full of small angular fragments of 
rhyolite; these range up to a third of an inch in length, and show 
up well on the weathered surface. (See fig. 4, p. 252.) The coast 
runs with the strike of this band for a long distance. 
A (16). These are thinly-bedded calcareous flags, containing coral- 
layers, and becoming at times somewhat conglomeratic. They 
occupy the point south-west of the Stone Cross, and can be followed 
in a north-north-easterly direction along the top of the cliff, as far 
as west of the Penitential Station. They have yielded the following 
fossils :-—
