Weathering of coastal defensive structures in southwest England : a 500 year stone durability trial

Auteur :
MOTTERSHEAD, D.N.

Description :
Several structures of Henrician (sixteenth century) and greater age on the coast of southwest England have been exposed to coastal salt weathering for 500-600 years. Long-term weathering rates on 5 different rock groups are derived from careful study of weathering depths and forms. Rank ordering of weathering rate values reveals a durability order of these rock groups. Specific density, and combined quartz and muscovite content, are positively related to durability; high feldspar and chlorite content are associated with low durability.
