Fuller, J.G.C.M. & Torrens, H.S. (2010). Murchison in the Welsh Marches: a History
of Geology Group field excursion led by John Fuller, May
8th - 10th,
1998. p.1-16.
Within the field area of the Welsh Marches, centred on Ludlow, the excursion
considered the work of two pioneers of geology: Arthur Aikin (1773-1854) and
Robert Townson (1762-1827), and the possible train of geological influence from
Townson to Aikin, and Aikin to Murchison, leading to publication of the
Silurian System in 1839.

Pannett, D. (2010). Glacial Meltwater Channels of the
Stiperstones Area. p.17-19.
Consideration of recent contour maps reveals that glacial meltwater channels in
the Stiperstones and Long Mynd areas have elevations compatible with an ice
margin sloping from west to east cutting across SW-NE ridges where they would
have dammed water in the heads of the valleys, forcing some flow across cols in
the main watershed. Such channels suggest that ice once lapped around the
Stiperstones to a height of at least 330 m.

Cook, S.J. (2010).
The glacial geology of Shropshire: insights from modern glaciology. p.20-27.
Shropshire contains a rich landform and sediment record related to former
glacial activity, yet relatively little palaeoglaciological research has been
undertaken in the county. This paper argues that further research is required to
resolve key questions about: (1) the extent and dynamics of Devensian ice masses
in the West Midlands, and (2) the origins and ages of specific landforms and
sediments. This review is written from a modern glaciological perspective and
highlights areas where existing ideas about the nature of glaciation in
Shropshire and the origins of Shropshire's glacial landforms and sediments
requires revision in light of advances in our understanding of modern glacial
processes. A number of avenues for future palaeoglaciological work in the county
are proposed.

Torrens, H.S. (2010).
John Randall (1810-1910) as Writer and Geologist.
p.28-43.
Randall is best known as a Shropshire historian, of especially the Madeley area.
He earned his living as a china painter (one of the best at Coalport - which
brought him into contact with local raw materials - which he described in his
Clay Industries book of 1877), then printer, postmaster and local councillor.
But John Randall's was an extra-ordinary life, both as a centenarian, but also
as a prominent amateur geologist and author, the roles examined here.

Smith, D.C. (2010).
Quizzical Quartzites: some personal observations concerning the origin of some
well known Shropshire examples.
p.44-46.
Most Shropshire
'quartzites'
are described in the literature as strong pale
sandstones and explained as being of shallow water sedimentary origin. Recent
observations by the author has raised doubts about each of them: outcrops of the Rushton Schists are of metasedimentary country rock, intricately overprinted
with granite-like veining. One nearby outcrop is mapped as Wrekin Quartzite, but
it seems to be a genuinely metamorphic quartzite. The Wrekin Quartzite is
enigmatic: at the Ercall quarries the lowermost several metres are arkose, not
quartzite at all; they are rough, gritty, debris-rich sediments containing
debris of older basement rocks, together with much greenish silty shale, veined
and cemented with barite, and disturbed by small faults. The Stiperstones
Quartzite shows characteristics typical of deep water mass flow deposits and may
thus not be shallow marine at all.
