Forthcoming Events

Saturday 8 June 2024

10:30am   Emmer Green and Clayfield Copse. Led by Ross Garden.

Meeting point - Clayfield Copse Car Park, Caversham Park Road GR: SU 7258 7678; Lat:Long: 51.4853346, -0.9560866; W3W: ///using.sparks.echo

Clayfield Copse in Emmer Green is the only outcrop of London Clay north of the Thames in Berkshire. It is surrounded by clays and sands of the Reading Beds (Lambeth Group) which unconformably overlie the Upper Chalk (Seaford Chalk Formation). The outlier occurs in a N-S oriented down faulted graben adjacent to a horst of uplifted chalk which separates Emmer Green from the hamlet of Dunsden Green to the east.

Exposure is poor, but by looking at drainage and spring lines we can approximate the formation boundaries. The walk will take us across the Clayfield Copse graben and the Littlestead Green horst and down to the Henley Road where fractured Seaford Chalk is well exposed in a roadside quarry. The return will take us through Dunsden Green where we will see All Saints parish church where Wilfred Owen was a lay assistant to the parish priest before the First World War. The church is made from Reading Beds bricks and we will walk up and through the former Emmer Green (Rose Hill) brickworks and past the 89th Reading Scout Troop hut which is the site to one of the entrances of a chalk mine used for brick making.

The objective of the walk is to discuss the style and controls on faulting in this part of Berkshire and the impact on the economic geology.


Wednesday 12 June 2024

7:00pm   Annual General Meeting

Meeting point - Woolhampton Village Hall, Bath Rd, Woolhampton RG7 5RE, SU 5708 6681

Details to follow


Saturday 20 July 2024

10:30am   Hermitage area walk led by Clive Edmonds

Meeting point - Hermitage Village Hall car park GR: SU 51121 73992; Lat/Long: 51.4626028, -1.2655170; w3w: ///breathed.bearings.nametag; Nearest post code RG18 9WL

Using footpaths we will visit the site of an historical chalk mine that caused construction problems for the M4, recent residential development problems in the village, then venture to Oare with a chance to view building stones and grave yard at St Bartholomew’s Church, before crossing up onto Oare Common (formed of gravel capped Palaeogene sequence above Chalk) and going downhill again towards Doctor’s Lane to view a series of sinkholes and return via a quiet lane to Oare viewing an old brickworks site on the way with its former shaft entry chalk mine as well. Finally returning to the start – a walk of about 3 miles or so.
