GEOLOGY, BY DR. BOASE.
St. Enedellyan has been long celebrated for its mines of antimony. This metal occurs in the state of a sulphuret, associated with iron pyrites, in quartz veins, which run east and west, traversing a blue lamellar slate, very similar to that which frequently abounds in the calcareous series, and to which, indeed, this slate belongs. Some curious varieties of rocks in this series are found in St. Enedellyan, one of which, in particular, abounds between the church and Port Isaac, which was noticed by Sir Humphrey Davy in a decomposing state, under the name of mandelstone. In this state it is a dull earthy argillaceous rock, of an ochreous colour, full of small, roundish cavities. In its perfect state this rock is a greenish-grey, glossy, compact felspar, containing granules of flesh-coloured calcareous spar, and minute prisms of hornblende. During decomposition, the calcareous spar is dissolved, and washed away by the rainwater, which produces the honeycomb appearance; and the ferruginous stain is derived from the iron contained in the hornblende. This rock has been described by Mr. Prideaux as occurring in Devon. It is very rare in Cornwall.
