This parish offers many objects of considerable interest to the geologist. It is entirely situated on rocks belonging to the calcareous series. In the southern part, its rocks consist of clay slates possessing various degrees of fissibility, from the most perfect roofing-slate of Delabole, to a slate that can only be separated into thick flags. Amongst these strata occurs an interesting rock, which appears to be composed of hornblende and compact felspar, and in some parts of hornblende and calcareous spar only. The latter variety is well known in the neighbourhood under the name of green freestone, and may be seen in the walls of the oldest churches. It is in situ in a croft near the pretty little waterfall of Nathan's or Kneighton's Kieve.

In the northern part of the parish, near King Arthur's Castle, and in Bossiney Cove, the slate is very talcose, and is occasionally coated at its joints with calcareous spar. At the former place also occurs a large mass of compact felspar, but which is so much decomposed that its precise nature has not been ascertained. In the sea-cliffs are several slate-quarries, the quality of which, however, is inferior to the Delabole, and is known in the market by the name of cliff slate. In this slate are impressions apparently derived from shells, which have been referred to the genus producta. This is the only instance of a fossiliferous slate hitherto detected in Cornwall, though it is probable that others may exist, particularly between St. German's and the Rame Head.
