John Wong AGS Field Trip
Sunday 20th August 2017: Geology Around Shepshed And Thringstone, Leicestshire.
Led by Keith Ambrose and John Wong
John has invited Keith Ambrose to lead this field trip. Keith is the former regional field geologist for the British Geological Survey and knows the geology of the East Midlands area well, especially Leicestershire.
We will visit six or more localities depending on the time available and accessibility of the sites on the day. At Grace Dieu Priory ruins there are building stones from the local Charnian Supergroup, tuffs and Peldar Dacite Brecccia, Carboniferous Tickow Limestone and Precambrian North Charnwood Diorite. At Cademan woods there is an outcrop of Grimley Andesite of the Whitwick Complex. At Grace Dieu inlier there is the most southerly exposure of the Peak Limestone group, formerly the Carboniferous Limestone. In a disused quarry near Calvery Rock there are exposures of secondary tufa and Triassic breccia. West of the Grace Dieu Brook there is Carboniferous dolomitic limestone below the Triassic unconformity. The Triassic outcrops are of the Shepshed Sandstone member, formerly known as the Lower Keuper Sandstone. Shepshed Sandstone was once worked for lead minerals. At Ticknall Lane bridge there are glaciofluvial deposits of the Pleistocene.
There will be a lunch stop at a local public house or you can bring a packed lunch if you prefer.
In JULY and AUGUST I am organising three trips down the Darent Valley in Kent. This is arguably the most picturesque and interesting area near London. Arthur Mee ( editor of The King’s England series of county guide books ) built his house overlooking Eynsford and described his view as “ unique on the map of rural England”. Come and see if he was right!

Half-Day informal discussion/workshop at Trent Country Park Cafe: Glacial erratic fossils and Cretaceous phosphatic nodules (coprolites?) from Barrington Quarry, Cambridgeshire, led by John Wong.
Back in 2010, John led a field trip to the quarry which is famous for the youngest geological age ichthyosaur having been found there in the chalk in 2005. During the AGS visit numerous fossils were found including a marine reptilian tooth, fish scales and bones, shark teeth, bivalves, brachiopods, ammonites etc. This was followed by a visit to the NHM to see the ongoing conservation and restoration work on the fossil ichthyosaur skeleton.
During the workshop, the fossil finds will be discussed, therefore any AGS members with rocks and fossils from the 2010 visit to the Barrington Quarry please remember to bring them along. Please book your place using John Wong’s normal contact details which can be found in the latest newsletter.
THURSDAY 6 APRIL 2017: ‘The Pulhamite Industry’ in Hertfordshire’.
We will start at the café alongside the River Lea at Broxbourne about 200 yards south of Broxbourne station at 11 am. We will look at the watermill remains then walk along the New River past Broxbourne church to the site of the Pulhamite factory where this type of artificial stone was produced.

PRECAMBRIAN VOLCANIC and PLUTONIC ROCK PETROLOGY and TRIASSIC ROCKS SEDIMENTOLOGY and STRATIGRAPHY at BARDON HILL WORKING QUARRY, BARDON, WEST LEICESTERSHIRE
– Led by John Wong
Please see ‘Gallery’ for photos of the trip
Geology of the late Precambrian ocean island arc volcanism and the paleo-environments of the Triassic Period in the deepest quarry in England. The stratigraphy is complex and the geology is significant because the quarry exhibits many of the Precambrian rocks whereas other areas in England have very low exposures. In the quarry there are large scale folds and faults of the Caledonian Orogeny, and spectacular pre-Triassic buried paleo-landscape. Full details in the A.G.S. October newsletter.
Every participant must comply with Bardon Hill Quarry’s personal protective equipment regulation – hard hat, high-visibility jacket (not vest), high visibility trousers, gloves, lace-up boots and safety glasses. You will not be allowed to go into the working quarry if you do not come with full personal protective equipment as required by the quarry management.
AGS Field Trip, led by John Wong

MIKE’S Car Trip and Walks
Mike’s ‘Bucks, Geology and Churches trip # 2’ Sat 10th September 2016
A small group, 11 in all, met up at Dinton church at 10.30 am. After examining the building stone, a local variety of Portland stone which is creamy and full of casts and moulds of bivalves, we tried to interpret the tympanum above the Romanesque doorway. Dragons eating the fruit of the Tree of Life and St Michael fending off a fire-breathing Dragon??
We then visited two Wichert villages, Westlington, really just a hamlet, and Cuddington in a torrential downpour. Wichert is crushed limestone rubble mixed with clay and straw and the MUD cottages produced have distinctive rounded corners and un-ever walls.
After lunch in the Bugle Horn Inn, which has giant ammonites set into the car park wall, we travelled to Stone church to see its unique ‘PAGAN’ font where I tried to explain the iconography – everyone was suitably bemused. Our final stop was the hill-top village of Brill where the surviving windmill was surrounded by a ‘moonscape’ of old brick-pits. Rather than look for these in the sodden grass we retired to the Pheasant pub for a well-deserved coffee and a wide ranging discussion mainly centred on Brickmaking and Fracking. – Mike Howgate
See ‘Gallery’ for photos of the ‘walk’……
Friday 16th September: 1066 and all that in London with Mike
The City of London was never conquered by Duke William and so as a city guide I am not allowed to call him ‘the Conquerer’.

SATURDAY 15 APRIL 2017: ‘THE GEOLOGY AROUND SOUTH MIMMS, HERTFORDSHIRE’
A day trip for the Geologists’ Association with the Kirkaldy Society.
In the morning will search out the evidence for geologically based industries in the small area around Pinks Farm between Ridge and Ridge Hill. We will spend about two hours exploring the area, where we will find dean holes dug by Chalk Drawers (now a bat hibernicularium), Old Chalk quarries, brick and sand pits ( one of which is featured on William Smith’s 1815 map), in what must have been a hive of extractive industrial activity 150 years ago.
After lunch in the nearby Old Guinea pub which doubles as a pizzeria we will examine the geomorphology of the area in a three mile walk from Ridge village across the Stanmoor Gravel plateau and follow the Catherine Bourne to its terminal swallow hole.
To book on this trip contact Sarah Stafford at email@example.com there will be an administration fee of £5.
ONLY 7 PLACES REMAINING! Mike Howgate
