Crump, L. & Donnelly, R.
(1994). Coal mining: a unique opportunity at Clee Hill, p.1-53
Clee Hill Quarry is an active hardstone (dolerite) quarry in Carboniferous Coal
Measures which have been intruded by a thick (ca. 60 m) conformable fine-grained
olivine-dolerite sill.
The whole sequence is now folded into a broad synclinal structure and is
extensively faulted. The area is blanketed by glacial deposits, 2-12 m thick.
Historically, quarrying operations have been closely allied to the geological
structure being confined to the margins of the syncline where the dolerite is
devoid of overlying Coal Measures.
In 1973 a programme was undertaken to assess the viability of using Coal
Measures material for the production of lightweight aggregate. This programme
was initiated because virtually all remaining, albeit substantial, planned
reserves of dolerite were overlain by considerable thicknesses of Coal Measures
and glacial deposits. Initial results from a technical viewpoint were
encouraging. The project was eventually begun and the mining phase, including
the major restoration works, was completed in July 1992.

Woodcock, N.
(1994). The Welsh Borderland Fault System - still active after 600 million
years, p.4-6
The Welsh Borderland Fault System comprises three major strands: the Church
Stretton Fault, the Pontesford Lineament and the Towy Lineament. In the latter
two cases the fault zone exists at depth and is represented at the surface by
alignments of topographic features and surface structures. The general alignment
of the system is due to its having had its major period of movement in
Caledonian times. Evidence is presented to demonstrate that there may have been
a lot more movement on these faults that was previously appreciated.

Palmer, T. (1994).
Hard bottoms, p.19-21
Hard sea bottoms arise on the sea floor when soft sediment, the majority being
of terrigeneous origin, includes grains consisting of calcium carbonate which
eventually lithify to form limestone. The grains are either precipitated
directly from sea water or, more commonly, from organisms.
Hardgrounds may at first sight appear to be an unusual and esoteric
phenomenon, but in practice their study is able to extend consideration in time
and scale of large-scale climatic and chemical processes, and on evolution
patterns.
