The main area occupied by Silurian rocks may be divided 
for convenience into four parts, which extend from near Aston 
Ingham in the north to Flaxley in the south. 
Of the four parts which form this main area the most 
northerly one extends from near Aston Ingham to the northern 
slope of May Hill. It is much broken by faults, which run 
more or less from east to west, and is bounded by faults on its 
eastern and western sides. On the south-west the Silurian beds 
are inverted and faulted against Old Red Sandstone. 
The next part to the south covers May Hill and Glasshouse 
Hill and shows a normal anticlinal structure (vide Section A). 
On its eastern side there is a fault which brings Old Red Sand- 
stone against Llandovery beds, Woolhope Limestone and 
Wenlock Shales, while on its western side Old Red Sandstone
