GEOLOGY, BY DR. BOASE.
The Geological structure of this parish is precisely similar to that of Callington; but, as it is better developed, it will admit of a little more detail.
The northern part consists of the granite of Hingston Down, which is crystalline, and it is extensively quarried for economical purposes. The quarries near the summit of Kitt Hill afford excellent illustrations of the internal structure of the granitic mass. On this Down, beds of fine-grained granite project here and there above the surface, resembling that which occurs as Elvan courses in the adjacent slate. The latter rock consists of a basis of granular felspar, spotted and spangled with a shining-mineral like mica. This slate, as well as the granite, have been long explored for tin and copper. Shorl and mica generally abound in the lodes; and the former mineral is often so intimately combined with the quartz, as to form a dark-coloured compact shorl rock. Southward the slate becomes more blue, and is fissile into extended slabs. Near the village of Calstock it is soft and lamellar, having evidently graduated into the calcareous series. At Cotehele, near the landing place, a beautiful oved-coloured calcareous schist is quarried, which is said to prove a good material for lining kilns and ovens: it has a shining talcose appearance, resembling that of Trenalt, near Pallephant, in Alternon.
