The importance of geologists in war planning was fully recognised by the British in World War II, and Prof. Shotton was engaged in the Royal Engineers as a Staff Officer - Geology, along with a number of other geologists. The team was engaged in one part of the overall strategy: mainly the study of the beaches over which men and equipment would have to travel. The task was to prepare maps of the French beaches, pinpointing the most suitable invasion areas.

The two localities chosen were already well known to members of our own Society: the Ercall Quarry and the Onny Valley.

Gold is not evenly distributed; either there is no gold at all, or it can occur in quartz at over 100 oz per ton. The Lower Lindula flags, or Clogau Shales, containing much carbon and pyrite, are overlain by quartz, with gold occurring in these beds in a circle around the Harlech Dome. Reedmay thought it essential to have intrusive greenstone close at hand, but this reasoning never seems to have been followed up. The mine strata dip at about 35? from West to East. The area is heavily faulted, and the occurrence of greenstone is unpredictable. Geologists consider that gold occurs at the junctions of faulted lodes, and could have been waterborne through cracks in the rock.

The film on glaciers provided a serious geomorphological study of the characteristics of various examples. The film on earthquakes invoked what might be described as ?social geology?, describing the history of earthquakes in San Francisco, the type of monitoring currently carried out along the San Andreas fault and its offshoots, and the attitudes of the residents and researchers in the area.

Description of a pliosaur fossil found in a working quarry at Westbury in Wiltshire. The sequence exposed in the clay pit extends from the Rasenia cymodoce Zone to the Aulacostephanus eudoxus Zone, Lower Kimmeridge Clay. The pliosaur remains are from the Aulacostephanus eudoxus Zone. The horizon from which they were obtained forms a lithologically persistent horizon throughout the English Kimmeridge Clay, from Dorset to North Yorkshire. It is thought that the pliosaur may be a new species, although further work on this aspect is required.

The talk was based on a comprehensive series of slides taken by Dr. Brown over many years, as a record of the mining history of the Stiperstones area. Several of the slides consisted of old photographs taken of the mines and miners during their heyday in the late 1800's and up to as late as the mid 1900's. Original pictures of the remaining minehead gear and buildings, taken over the last two decades, now form an invaluable record.

Mapping in the vicinity of Wenlock Edge has been conducted with the aim of locating alternative sites to the oft-visited localities quoted in the literature, and to provide some variation in the exposures located. The area covers from Brockton to Bourton on the B4378, from Easthope cross-roads on the B4371 to Presthope.
It has been possible to locate several fairly accessible sites which certainly would warrant closer attention than time at present has allowed, the piece de resistance being the famous J. Krause ?heads here and tails there? trilobite site.

The field excursion to the Lion Salt Works and the Salt Museum, Northwich, was to gain an insight to the salt production process.

The field excursion visited a small domestic quarry on the Long Mountain. This exposure is in the Wenlock Series of the Silurian: deep water graptolitic shales. There was evidence of some changes in places, due to the proximity of intrusive bodies; a few fossils were uncovered in the dark grey brown weathering shales. Middletown Quarry on the eastern side of the Breiddens was then visited. The quarry itself is a small circular volcanic plug and the material being excavated is a greenish feldspathic, rather soft granitic rock which is deeply weathered and chemically altered. There were shafts and adits also in the area, which indicated some evidence of past copper mining activity.

Study of the Ludlovian rocks of Silurian age which are found between the valleys of the Teme and Lugg, west of Knighton. The exposures visited were in what is known as the ?basin? facies of the Ludlow Series, including Knighton, Dutlas, Felindre, Black Mountain, Rhoscrug and Crug. They represent accumulations of material in a variable depth, and often tectonically active, offshore zone. They are equivalent in age to the shallow water ?shelf? facies of the Ludlow area, but the thickness of the basin deposits is greatly in excess of the thickness of the shelf deposits.

Ludlow Museum celebrated its 150th anniversary at the Feathers Hotel, Ludlow, on the 12th October 1983. On the 12th October, 1833, the Museum and Ludlow Natural History Society was founded by a group of local naturalists. Amongst these were the Rev. T.T. Lewis of Aymestry and Dr. Thomas Lloyd of Ludlow. It was their pioneer work on local geology which provided much of the information used by Sir Roderick Murchison, in his work on the geology of this part of the Welsh Borderland.
