    'Geology of the Chiltern Hills; new data & new interpretations'

    'Geology of the Chiltern Hills; new data & new interpretations'   7.30 -

    Monday 15 April (Indoor Meeting): 'Geology of the Chiltern Hills; new data & new interpretations'. Speaker: Dr. Haydon Bailey (Geological Adviser, The Chiltern Society).
    The Chiltern Hills are underlain by Chalk, predominantly lithostratigraphic units traditionally called the Lower and Middle Chalk (the latter now the lower part of the White Chalk Group) capped by the Top Rock - Chalk Rock complex. It is this series of chalk hardgrounds which effectively forms the spine of the Chiltern Escarpment. The Chalk dips gently into the London Basin, and the overlying basal Tertiary succession provides minor outliers around this northern rim of the basin. The other major geological event we have to recognise in this area is the re-routing of the Proto-Thames River during and following the Anglian glaciation, some 450,000 years ago. This created the landscape we currently see in much of the southern parts of the Chilterns. Geological mapping of the region by the BGS over the last ten years and ground investigations resulting from the ongoing construction of the HS2 High Speed rail link have greatly added to our knowledge of the regional geology. Add to this the recognition that subsurface movement of water through the chalk is far more prevalent than previously identified, then this means that we're still learning a whole load more about the geological development of the hills which form the northern margin of the London Basin.

    Field Meeting on the Central Malverns Complexes

    Field Meeting on the Central Malverns Complexes   10.00 - 4.00

    Saturday 11 May (Field Meeting): Central Malverns Complexes. Led by John Moseley (Gloucestershire Conservation Trust). Meet at 10.00 in Upper Tollgate Quarry (also known as Upper Wyche Quarry) which is used as a car park GR: SO7695 4395. This is the more southerly of the Tollgate Quarries. Parking costs £5.50 for the day, but covers all the Malvern Hills car parks if we need to move. Payment is by card only. Bring a packed lunch.

    At the Tollgate quarries we will look at the Upper Silurian and Llandovery/Malvernian unconformity. Here there is a good range of foliated rocks of igneous origins, mainly granitic and dioritic, and evidence of a sheared dyke, and an enigmatic feldspar-hornblende-biotite rock. Here we can open discussion on topics such as metasomatism, and brittle and ductile shearing.  From the Tollgate quarries, we will walk through the Wyche cutting, where there is evidence of mylonites and pseudotachylites. Then there will be a short walk onto Perseverance Hill to observe granitic rocks with gneissose and schistose textures.  From here there are excellent views, and a chance to put the Malvernian in its regional context. 

    After lunch there are various options: a section through Upper Silurian on the west side of the Malverns (quite close to Wyche Cutting) and/or Gullet Quarry for the Llandovery-Malvernian unconformity. Total walking: approx 4km. Aim to finish by 4.00.
