Excursion Details
Saturday 7th & Thursday 12th April 2018 — Gillfield Mine

Leader: Shirley Everett, former manager at Coldstones Quarry.


A guided walk of three miles with a very gentle walk up the hand cut adit which goes through the northern limb of the Skipton Anticline and drains the mine, where we will see the recently restored workings in the Waterholes Vein and scramble up into the Sun Vein to see the causes of deposition of the Galena and Fluorite and how they were worked at different times.

Geology: Carboniferous.

Sunday 15th April 2018 — Bramham - Boston Spa - Wetherby Area

Leaders: Jeremy Freeman and Malcolm Barnes (Yorkshire Mid-Week Geology Group).


To see most of the sequence of the Cadeby Formation in the Bramham-Boston Spa-Wetherby area.

Geology: Permian.

Wednesday 9th May 2018 — Roundhay Park

Leader: Bill Fraser, Leeds Geological Association.


A guided walk of approx. three miles mainly along made paths but with one steepish ascent and descent through woodland, following the Geology Trail that was established as a joint venture between the LGA and the Friends of Roundhay Park in 2008. The ten locations along the trail illustrate changing sedimentary environments in the Millstone Grit Group (Rough Rock and underlying beds) and some interesting local and regional structural features. Copies of the Trail Guide and other handouts will be provided.

Geology: Carboniferous.

Thursday 7th June 2018   —   "Yorkshire's Jurassic World" Exhibition


To look at the newly opened Jurassic exhibition at the Yorkshire Museum.

Geology: Jurassic.

Saturday 28th July 2018 — Loxley Edge Rock and Wharncliffe Edge Rock

Leader: Dr Gareth Martin, Leeds Geological Association & West Yorkshire Geological Trust.


A short trip to two sites to see paleo-environmental changes and superb sedimentary features in the Carboniferous Lower Coal Measures, Loxley Edge Rock and the rarely exposed Wharncliffe Edge Rock formations.

Geology: Carboniferous.

Maps and references:

BGS Barnsley 1:50000 Sheet 87.

Saturday 1st Sept 2018 — South Hylton and Castletown, Sunderland

Leader: Michael Mawson.


During this fieldtrip desert sandstones of the Yellow Sands will be seen as well as the top Carboniferous / base Permian unconformity below which the youngest Coal Measures to outcrop in northeast England are exposed. The Yellow Sands are overlain by the Magnesian Limestone (now called the Zechstein Group) which comprises, at its base, the Marl Slate (known for its well preserved fossil fish and plants) overlain by the limestones and dolomites of the Raisby and Ford formations, the latter containing a fossil reef with a wide variety of fossils. The equivalent of these two formations further south, in the Yorkshire outcrops of the Zechstein, form the Cadeby Formation.

Geology: Carboniferous, Permain.

28 - 30 Sept 2018     —     Residential Weekend: Norfolk Coast

Leader: Dr David Waterhouse, palaeontologist and Senior Curator of natural history at Norfolk Museums Service.
