Rotunda Geology Group

Just a few pics of the Chalk at Flamborough. This was on a YWT Living Seas boat trip. From what I remember this is all in the Burnham Chalk formation. The flints are paticularly well displayed in the cave. Our July trip is going to be even more interesting as it will show us some remarkable structures which aren't visible here.

A local find! Let's hope it's recovered for the museum 🤞

William Buckland: glacial impressions The event highlights aspects of the search for evidence by the earliest advocate for the glaciation theory in Britain, William Buckland.

In conjunction with PLACE, a Wolds Research Group is forming that will be involved in producing a publication and conference (aimed for 2022) on documenting the geology, geography, history, archaeology and natural history of the Yorkshire Wolds. If you would like to make a contribution - of any kind, a small project, photos, art work literature, poetry or helping with a larger research project - please contact Laura Eddey or Richard Myerscough (emails available if you message the page - I don't want to open them up to spam mail by putting their addresses here).

Sarah Caldwell Steele is on the hunt for fake jet

Geologist’s quest for Whitby jet test marks a black day for fake gems Jewellers in Whitby have been waiting since Victorian times for a way to tell genuine local gems from fakes. Now their wish could be granted, with the prospect of a non-destructive test to show

Know your sinkhole!

Cornelian Bay and Osgodby Nab, just north of Cayton Bay. A reasonably quiet bay, as its a bit of a scramble down to the beach. You're rewarded with some fantastic geology, however, ranging from ~150 ma to 20 ka.

The rocks here start with the Long Nab Member of the Scalby Formation. The cliffs are till overlying outcrops of Oxford clay at the south, with the Osgodby Formation outcrops in the center. Portions of Moor Grit are also exposed at the coast line. You can occasionally see the sections of the Cayton clay at low tide, and it looks like chunks of it have been incorporated into the Filey till (see photo with keys).

You can see the Cayton Bay fault running almost parallel to the coastline.The Cayton fault has an up throw of 110 m to the east. The pillbox at the south end sits on the Millepore Bed, while the Oxford clay is seen to the west (Rawson and Wright, 2018). There's the outline of an old channel that you can see at low tide, revealing something about the coastline's past, potentially as a glacial meltwater channel.

The exotic lithologies of the glacial pebbles and gravels washed out of the till will make some great additions to any rock collection. I was thinking that it was the Kellaways exposed here, below the Oxford Clay, but I'm not sure the term "Kellaways" is used anymore. Someone told me trying to figure the geology here would drive me mad.

Rawson and Wright. 2018. Geology of the Yorkshire Coast. GA Guide no. 34 definitely needed.

We should definitely be marking the 23rd of April (although I'm a day late) as the day John Phillips died in 1874. He's buried in York. Phillips is the artist behind the fresco around the base of the dome at the Rotunda (unfortunately, I don't have an image of that). Phillips also published the first global stratigraphic chronology with associated index fossils, and the nephew of William 'Strata' Smith. 🦕🦖🦕⚒️🦴⚒️🦴⚒️🦕🦖🦕

If you walk along the beach from Filey to Reighton Gap, these are some of the pebbles you'll see.

They're a mixture of local and far-travelled stones. Locally, there are sedimentary rocks, like limestone, sandstone, and chalk, but mixed in are some igneous rocks, like granite and basalt, that are from Norway and Scotland.

All of these rocks were broken by and picked up by the massive glaciers that reached the Yorkshire coast in the last Ice Age (21,000 years ago). They were left at the edge of the ice in a moraine made up of all sizes of rocks from big boulders to sand, gravel, and clay. This is what the cliffs along the coast are made from.

When the sea hits come in, the water erodes the finer particles (sand and clay), but can not carry away the bigger rocks and so they are left on the beach. These are some of my favourite ones. Sometimes, you can find fossils from further up the coast, old Roman or medieval pottery and pieces of jet.

The Mid-Jurrasic Scalby Formation at the northern end of North Bay, Scarborough next to get the Sea Life Centre. Part of the Ravenscar Group, a deltaic-fluvial deposit characterised by the fining upwards of the sedimentary sequence.

The Scalby Formation is divided by this change into the lower Moor Grit Member, with medium to coarse sandstone, and the overlying Long Nab Member, which has more fine grained siltstones and mudstones. Essentially, this means that you can see more individual sand grains in the lower half of the Formation and the stones become smoother as you move up the sequence with less of a sandy feel.

last years trip to South Landing and Danes D**e on the southern side of the Cretaceous-aged, chalkly Flamborough peninsula. A photo of Rodge Connell who regularly leads field trips to the area. Ice didn't quite make it all the way over the peninsula and was somewhat restricted by the chalk ridge. Some of the valleys are filled with glacial sediment and there are meltwater channels and till deposits. The area was mapped first by George Lamplugh and later by John Catt.
