59. Geology of Hadrian's
Wall (1997)
G.A.L.Johnson
£15.00
The geology of Hadrian's Wall falls naturally
into three sectors: in the East the wall
is over Upper Carboniferous Coal Measures and
Millstone Grit; the Central Section
is underlain by Lower Carboniferous intruded
by the Great Whin Sill and in the
Western sector the Wall crosses the New Red Sandstone.
Glacial drift is widespread.
All three sectors are described with specific
sites in detail.
