Field
Trips which took place in 2010
Sun.
May 2nd. Cayton
Bay. Meeting at Killerby Park, (grid ref.TA 069 841) at 10.30am. Dr.
Martin Whyte advises the following: The parking fee at Killerby Cliff
is £2 for the whole day.This is paid at a machine on entry so
drivers should have the coins with them when they arrive.The
road layout has changed since the guide in "Yorks. Rocks &
Landscape" was written. Cf. map below: turn off the new A165 at
the roundabout, and take the Filey Road (old A165) to get to
the Killerby Cliff/car park access road. Meet at the point marked A
on
the map. The purpose of the trip is to study the succession,
depositional history and palaeontology (including plant beds) of the
Middle Jurassic (Lebberston Member) to Upper Jurassic (Lower
Calcareous Grit Formation), the Redcliff Fault, Quaternary tills and
examples of mass movement. Safety helmets should be worn if close to
the cliff face. The considerable large succession of rocks which can
be examined here is in part due to the Redcliff Fault, downthrow to
the north west resulting in Upper Jurassic rocks to the north west
being juxtaposed against Middle Jurassic rocks to the south east.
Leader: Dr.
Martin Whyte
Sat. June 19th Durham Permian: Meet at car park near Claxheugh Rock. (NZ 3600 5755). See below for maps and instructions on how to get there) at 10.30 am down by the River Wear (excellent outcrops of the Yellow Sands and overlying Marl Slate, Raisby Formation, and Ford Reef), followed by visits, time permitting, to Seaburn on the coast, Lizard Pont and Marsden Bay, displaying Permian desert sands and overlying shallow-marine to deeper marine slope carbonates of the Raisby, Ford and Roker Formations. Beautiful exposures and nice sedimentology. Leader: Prof. Maurice Tucker.
Sun.
July 11th Time:10.30am
to 3.30 approx. Meet: Ingleton Glens Walk car park GR: 693735. Map
OS Outdoor Leisure 2 Yorkshire Dales, Western Area (1:25000), or OS
Landranger 98, Wensleydale & Upper Wharfedale (1:50000).
Purpose: The
excursion will examine the evidence for/effects of the Craven Faults
with the unconformity at Thornton Force. The glacial impact on the
area will also be briefly considered.
Route comments:
We follow a private footpath along the banks of the river Twiss.
There is a small entrance charge to the walk (£4.50, but a
reduced rate for parties could be arranged). Whatever the price, it
is an area well worth visiting!
Carboniferous
exposures give way to the Lower Palaeozoic’s with the
spectacular waterfall coincident with the terminal moraine location.
The fault
exposure is wide and has clast variations reflecting the rocks
affected. Length 5 kms in total. A large car park is available at the
start of the walk.The group will return along the picturesque River
Doe to Ingleton. Outdoor clothing, strong footware and a packed lunch
are appropriate. Personal first aid kit, as always, advisable. Leader Gordon
Liddle.

Sat.
Aug. 14th Joint
field meeting with the Natural History Sociey of Northumbria:
An
Introduction to Glacial Sediments at Whitburn Bay.
Met at the
coastal car park to the south of Whitburn village at 10.30am
[NZ408
614], about 2.5 miles north of the Sunderland coast. One mile of
gentle walking across beach sands and cobbles. Whitburn Bay has
outstanding exposures of sediments deposited during the last glacial
episode (about 26 to 15 ka BP). Recent detailed studies by Bethan
Davies at Durham University and the visit leader have uncovered a
wide variety of sediment types and deformation styles. A fascinating
story of competing ice margins has emerged that sheds light on events
across the whole of the North East. The visit examined almost all
types of glacial sediment found locally including tills, sands,
gravels, pedogenic overprinting and deformation. Leader:
Derek Teasdale.
Sat.
2nd Oct. Joint field meeting with the Natural History Sociey of Northumbria.
Nent Valley- Reading a Pennine Landscape.
Met at 10.30am
at
the Visitor Centre car park, Nenthead. [NY781 436]. Many of the
geological and topographical features that give character to the
north Pennine landscape are beautifully displayed in the 8 kms or so
of this valley. On a walk from Alston, upstream to Nenthead, the
excursion looked at typical Carboniferous cyclothemic deposits and
their influence upon landscape and ecology, together with abundant
evidence of mining for coal, iron, lead, zinc and barium minerals.
The role of Quaternary processes in shaping the landscape were
also demonstrated and mineralogical sites of world renown were
visited. Leader: Brian Young Click
