Bantycock open cast mine at Balderton near Newark Notts
Saturday September 20, 2014 | 9:00 am to 4:30 pm
Bantycock Mine was opened in 1982 but had to be closed in 1993 when the availability of synthetic gypsum, produced as a by-product from the desulphurisation of coal-fired power station flue gases (FGD), led to a diminishing demand for quarried gypsum. Extraction of gypsum was then moved to the Kilvington opencast mine, a few kilometres to the south, where the smaller thickness of overburden (about 7 m, compared with more than 25 m at Bantycock) allowed the gypsum to be extracted more cheaply. Kilvington had previously been worked by Blue Circle to provide for its cement manufacture, but competition from other sources of supply and closure of the railway caused the operation to cease in the late 1970s. British Gypsum acquired the Kilvington site in 1995 and began extracting gypsum the following year. The subsequent growth in demand for gypsum-based building materials, expected decline in the availability of FGD gypsum, and exhaustion of the reserves at Kilvington (closed December 2007), led to the re-opening of Bantycock, which commenced mining in October 2007.
This quarry provides the best section in the UK of the Triassic – Jurassic Boundary.
The group shall be led by Andrew Swift into the quarry at 9.00am until 1.00pm.
The pit is near Balderton, not in the village itself. We will visit the Chequers Inn after the quarry in Elston where lunch can be taken for those who want it, and beer brewed on the premises for interested parties. That will be before we walk to Elston church to look at the Darwin family memorials. There are no Charles Darwin memorials, but lots to other members of his family, particularly his grandfather Erasmus Darwin, a brilliant man in his own right, born in Elston Hall, who published some of the first original thoughts about the theory of evolution.
For all quarry visits hard hats, reflective jackets and suitable footwear are essential, some sites also require eye protection. Some sites will allow under 16’s under adult supervision but please check beforehand, the supervisor will also need to wear the appropriate safety gear. Members should appreciate that they are responsible for their own safety.
The society’s insurance is against 3rd parties.
With all field events please book with the field secretary at least 10 days in advance so we can cater for numbers.
For anyone who has booked a place on the field trip and for any unforeseen reason they cannot attend. Could they give 48 hours notice to the Field Secretary, if we don’t receive such notice we will assume you can’t make it and try to fill the space instead.
