By far the largest portion of the district belongs to the Devonian period. The southern 

 part of the county from Malborough and South Pool villages to Bolt Head and East Prawle 

 is Metamorphic or Altered Devonian, interspersed with patches of Greenstone ; there is Green- 

 stone also about Prawle Point, and several patches of it are distributed within the Devonian 



area. 



Limestone rocks occur in the southern parts of Devonport, East Stonehouse and Ply- 

 mouth, extending about if mile nearly due east of Plymstock church ; there are also patches 

 of limestone about Yealmpton, North Huish, Buckfastleigh, etc. 



The part of the district which belongs to Dartmoor is granite. The Carboniferous 

 system occurs to a limited extent round the granite area between it and the Devonian area. 



Mineral veins occur near Buckfastleigh. 



The climate of the district is illustrated by the following tables, which are obtained as 

 explained under the Barnstaple district : —
