Excursion Details
Thursday 29th April 2010    —     Gillfield Mine, Greenhow

Leader: Shirley Everett, Hansons Aggregates.

Purpose: To examine the geology and industrial history of the Greenhow area. The level was driven at right angles to the axis of the Greenhow anticline and goes through the sequence from the Red Scar Grit to the Greenhow Limestone. Only the limestone was mineralised in this area and workings for galena and fluorspar can be seen on both Waterhole Vein and Sun Vein (for a short distance).

Geology: Carboniferous.

Saturday 1st May 2010 — Roseberry Topping, Cliff Rigg Quarry & Ayton Banks

Leader: David Taylor.

Purpose: To examine the Lower Jurassic succession, the Tertiary Cleveland Dyke and Quarternary Devensian Deposits. Also remains of ironstone, jet, alum, sandstone, whinstone and sand/gravel mining and quarrying, extraction of which has resulted in a better understanding of the solid and drift geology.

Geology: Jurassic, Tertiary, Quaternary.

Wednesday 26th May 2010 — Duckmanton Cutting, Arkwright Town & Lodge House

Leader: Dr Paul Guion, University of Derby.

Purpose:

Duckmanton Cutting: SSSI and Derbyshire Wildlife Trust Reserve. Stratotype for Duckmantian European Stage. Contains Vanderbeckei Marine Band and exposures of Pennine Lower Coal Measures including Chavery and Sitwell Coals, mudstones with non-marine bivalves and ironstones.

Arkwright Town vicinity to view site of original village which was removed because of methane seeps to a new village and also restored opencast workings.

Lodge House Opencast Site, (entrance at SK 412 451, postcode DE7 6DW), Derbyshire. Worked by UK Coal to extract seams in Pennine Middle Coal Measures from Third Waterloo to Bottom First Waterloo. The sedimentology of the deposits will be discussed (lakes infilled by crevasse splays or lacustrine delta deposits). Methods of working will be explained, and a UK coal geologist will give an account of operations ranging from exploration to site restoration.

Geology: Carboniferous.

Saturday Morning 19th June 2010   —   Water Gardens, Fountains Abbey

Leader: Dr Neil Aitkenhead, BGS (retired).

Purpose: To examine the Lower Plompton Grit belonging to the Millstone Grit Group (Carboniferous, Namurian, Kinderscoutian – R1c) unconformably overlain by the Lower Magnesian Limestone or Cadeby Formation of late Permian age.

Geology: Carboniferous, Permian.

Saturday Afternoon 19th June 2010   —   St Mary's Church, Fountains Abbey

Leader: Murray Mitchell.

Purpose: To examine the building and decorative stones of the Church.

Maps and references: A very detailed handout will be provided.

Saturday 26th June 2010     —     Calton Hill and Miller's Dale

Leader: Dr Chris Arkwright, Open University.

Purpose: To examine igneous rocks in Derbyshire consisting of basalt lavas, tuffs and ashes which are seen interspersed amongst extensive limestone beds giving evidence of small-scale, mainly submarine, volcanic activity in Lower Carboniferous times. Associated dolerite sills, dykes and occasional volcanic complex were emplaced later in the mid-Carboniferous, intruding and cross-cutting the earlier lavas and limestones.

Geology: Carboniferous.

Sunday 25th July 2010   —   Bradgate Park, Leicestershire

Leader: Dr John Carney, BGS.

Purpose: In Bradgate Park we will see excellent exposures of the Bradgate Formation, consisting of medial to distal facies volcaniclastic turbidites in the upper part of the Charnian Supergroup. These strata were deposited in late Precambrian times, in seas that surrounded an active volcanic arc. The exposures include good examples of graded and disrupted bedding, and the deposits of a submarine landslide. A highly penetrative cleavage, which formed during late Silurian folding and compression, is very well developed here. At the very top of the Bradgate Formation there are conglomerates, deposited at a time when volcanism was waning and the volcanic arc was being exposed to erosion. Mudrocks of the (?)Lower Cambrian Swithland Formation, believed to be of Lower Cambrian age, will also be examined in nearby Swithland Wood, which is the site of a formerly extensive slate-quarrying industry. A famous fossil locality occurs in this park – we will not be able to visit this, owing to a confidentiality arrangement with the owners of the park, in return for access. (Some fossils have been recently vandalised). However, images will be shown of these and also some very new fossils – discovered elsewhere in the Forest over the past couple of years.The Park contains the ruins of Bradgate House, home of the ill-fated Lady Jane Grey, who reigned as Queen for 9 days.

Geology: Precambrian, (?) Lower Cambrian.

Saturday 21st August 2010   —   The York Moraine

Leader: Bill Fairburn.

Purpose: To demonstrate, on a traverse across the York Moraine, that persisistent terraces are in fact regressive strandlines of a proglacial Lake Humber. If this is the case, then current beliefs on the post-glacial evolution of the vale of York need to be revised (and Bill has done this).

Geology: Quaternary.

Fri 24th - Sun 26th Sept 2010    —    Residential Weekend: Pembrokeshire

Leader: Charlie Bendall.
