The northern part of this parish consists of felspathic hornblend rocks, belonging to the porphyritic series, which nearly touches the granite of Constantine and Budock. The southern part of Mawnan is situated on the calcareous series, and some of its rocks are very interesting, particularly those in the cliffs near the church and Rosemullion Head. MADDERN. HALS. St. Mad-darne, or Mad-ran, a Vicarage, is situate in the hundred of Penwith, and hath upon the north Sennor or Zeynar, west Sancret, east Gulval, south Paul and the Mount’s Bay.
