This fault zone has been proposed as a source of deep geothermal energy; to facilitate the design of a geothermal project in the town of Bishop Auckland further investigation of its geometry was necessary and led to the present study. We show using three-dimensional modelling of a dense local gravity survey, combined with structural inversion, that this fault has a ramp-flat-ramp geometry, ~250 m of latest Carboniferous / Early Permian downthrow having occurred on a fault surface that is not a planar updip continuation of that which had accommodated the many kilometres of Dinantian extension. The gravity survey also reveals relatively low-density sediments in the hanging-wall of the Dinantian fault, interpreted as porous alluvial fan deposits, indicating that a favourable geothermal target indeed exists in the area. -

Mid-Week Geology Group Newsletter November 2018
Mid-Week Geology Group Newsletter November 2018 John Williams Sheila Wilson Margaret Crawford Barry Tymon Programme planner Communications Treasurer Webmaster This is John’s last Newsletter before he stands down as Programme Planner. It takes our Programme to the end of May 2019. So far no individual has offered to replace John in this crucial role longer term. Meanwhile, to ensure continuity, I am pleased to report that three members have agreed to become part of a small sub group to arrange one or two events each next year. If anyone else wishes to become involved, please contact Sheila before the AGM. This newsletter provides further information on the 2019 Programme that was outlined in the June 18 Newsletter, with details of meeting points and what each event will cover. Our numbers have increased to 55 this year but actual attendance numbers at some events has reduced. Maybe some meetings are too far for some members? Or is it that most local locations have already been visited in recent years? We would like to discuss this issue further at the AGM. Our theme for the past two years as highlighted at the Skipton meeting is “How Geology Has Generated Industry in Yorkshire”. Many of our walks in 2017, 2018 and 2019 demonstrate this theme. The topic for our December AGM, however, seems to break away from this theme. Now that we know so much about the geology of our own planet, - as demonstrated by the many talks on faraway places that we have covered on recent Members Days – we will find out what the other rocky planets and moons of the Solar System may offer for the future. -
Near-Surface Palaeocene Fluid Flow, Mineralisation and Faulting At

We present new field observations from Selwicks Bay, NE England, an exposure of the Flamborough Head Fault Zone (FHFZ). We combine these with U-Pb geochronology of syn- to post-tectonic calcite mineralisation to provide absolute constraints on the timing of deformation. The extensional Frontal Fault zone, located within the FHFZ, was active at ca. 63 Ma, with protracted fluid activity occurring as late as ca. 55 Ma. Other dated tensile fractures overlap this timeframe, and also 15 cross-cut earlier formed fold structures, providing a lower bracket for the timing of folding and compressional deformation. The Frontal Fault zone acted as a conduit for voluminous fluid flow, linking deeper sedimentary units to the shallow sub- surface, potentially hosting open voids at depth for a significant period of time, and exhibiting a protracted history of fracturing and fluid-flow over several million years. Such fault-hosted fluid pathways are important considerations in understanding chalk reservoirs and utilisation of the sub-surface for exploration, extraction and storage of raw and waste materials. -

2018 Thursday – Whitby Shore and Cleveland Dyke with Paul Hildreth
th SEPTEMBER 13 2018 Thursday – Whitby Shore and Cleveland Dyke with Paul Hildreth Purpose of the visit To study the Lower and Middle Jurassic rocks of North Yorkshire exposed on the shore at Whitby. We will compare the litho- and biostratigraphies of the two major groups present (Whitby Mudstones and Saltwick Formation) and discuss their environments of deposition. Towards Saltwick Nab we will be able to study in detail the nature of the boundary between them. If time permits we can also consider the course of the River Esk and compare the geology of the two sides of the town. Meet: outside the Tourist Info. Centre Park: Harbour car park Itinerary Low tide at Whitby will be at about 1.15pm. For logistical reasons we will first visit an exposure of Middle Jurassic rocks west of West Pier before walking through Whitby to access the wave- cut platform at East Pier. The Lower Jurassic Whitby Mudstones are preserved in a syncline which also brings the overlying Saltwick Formation (Middle Jurassic) down to almost beach level. Here the Lower – Middle Jurassic boundary is represented by the Dogger Formation, a complex unit worthy of attention. There will be ample opportunity to look for and collect representative fossils which will include: ammonites (Dactylioceras sp. and Hildoceras sp.), bivalves, belemnites, plants (stems, leaves, rootlets) ichnofossils and, maybe, dinosaur footprints. On the day 12 of us met Paul at the car park near the railway station on a sunny but cold day after some had an exciting detour as the A64 was closed at York. -
