Avebury, Stonehenge, and South Wales Coalfield:
Avebury Oval is the larger scale Geologic Map of the Oval South Wales
Coalfield that had Double Basin Trough contours shown by Two Stone
Circles within the Coal Exploration Ditch before being destroyed. The
larger scale Avebury Oval mapping of the Oval South Wales Coalfield is
a reflection of Stonehenge Geologic Maps modeled by each Oval Double
Bluestone Horseshoe pair detailed with Gritstone (Millstone Grit) and
Whitestone (Carboniferous Limestone) from the South Wales Coast.
The Avebury Oval Coal Prospect is one of the largest Neolithic
Geologic Maps in Europe dating to around 5,000 years ago and older
than Oval Double Bluestone Horseshoe megalithic Stage of Stonehenge
Circle located 32 km (20 mi) to the south. Within the Coal Exploration
Ditch is the great Gritstone (Millstone Grit) Outer Oval packing
constituting prehistory's largest Geologic Replica by a Stone Oval,
the measurement of that Oval longest-axis being an approximate 336 m
(1,100 ft).
Geologic Mapping by Stone contours at the Avebury Oval Coal Prospect
began about four centuries (2600 BC) after its Coal Exploration Ditch
yielded no Home Heating fuel. Originally 98 Tertiary Sarsens in the
great Gritstone (Millstone Grit) Outer Oval packing stood as standing
stones. The Northern inner Double Basin Trough contours measured 98 m
(322 ft) in diameter and the Southern inner Double Basin Trough
contours measured 108 m (354 ft) in diameter before their destruction.
Avebury Oval Coal Exploration Ditch was 21 m (69 ft) wide and 11 m (36
ft) deep, about Double the Width and Depth of Stonehenge Coal
Exploration Circle Ditch.
