A narrow belt of slate, belonging to the porphyritic series, bounds
this parish on its eastern side, as far south as the village of
Mousehole; it consists for the most part of hard massive and schistose
varieties of compact felspar, occasionally spotted or intimately
blended with actynolite and hornblend, or with some mineral
intermediate between them. The rest of this parish is situated on
granite, exhibiting the same varieties as that of Burian and St.
Levan. At Mousehole the slate and granite may be seen in contact with
each other, the granite occurring as veins in the former rock.
