Triassic strata with dyke
A basalt dyke (left) intrudes gently-inclined sandstones of Triassic age on the shore. This is a wonderful exposure which highlights the difference in hardness and erosion potential of the two rock types. Rounded boulders of the black-coloured basalt lie all over the beach. They have been eroded from this and other dyke exposures nearby. A particular contrast in the type of intrusive rock, and in the inclination of the Triassic strata when compared with those found to the east. See also

Triassic strata
The foreshore to the west of Blackwaterfoot has fine, tilted outcrops of Triassic sandstone and mudstone which are characteristically red in colour, though this is obscured by barnacles in places. To the right of this image an intrusion of felsite makes a discordant feature.

Flow Banding in the Felsite
At first one could be forgiven for thinking this light coloured rock could be sandstone. These look like ripple marks, however they are probably flow banding marks.

Blackwaterfoot: rock-pools and seaweed
The combination of shallow rock-pools and slippery seaweed make for a hazardous walk along this part of the rocky shoreline.
Brown Head is the headland in the distance.

Felsite Intrusion
This looks like sandstone at first due to its colour, it even has 'ripple marks'. However why would this block of sandstone survive and the rest not. The answer is solved when looking at a fresh face through a hand lens. Small crystals can be seen. This is in fact a felsite, the same as the QFP in the area but without the phenocrysts. The 'ripple marks' are most likely flow banding remains.

Blackwaterfoot: pebbles, rocks and sandy beach

Shore with boulders
A view of the shore at low tide, where large, rounded boulders make small islands in the surf. In the foreground, smooth rock outcrop is notably pale in colour and very compact. This is part of a felsic sill intruding softer sandstones which have eroded away and become buried in the beach sand.
