Led by Alan Holiday. We will be looking at sections east and west of Kimmeridge. You will need to bring a packed lunch. Underfoot conditions: shingle and boulder hopping. So, walking poles may be needed. Likely finish time 4 pm. Please let us know if you would like to visit the Etches Collection Museum in Kimmeridge village as this can be included at your expense (£8 for an annual pass). Meet at the disused Portland Limestone quarry above Kimmeridge village,…Find out more »
Talk by Richard Hallett. It will give an introduction to Mesozoic microfossils, discuss their distribution in the local fossil record and contribution to understanding the stratigraphy of the Wessex Basin. This is the second of a series of Earth Science-based lectures organised by DGAG in collaboration with other groups. As the Dorset County Museum is closed for refurbishment, 'til summer 2020, the lectures will take place in Committee Room 1 at County Hall. They will follow the familiar pattern of being…Find out more »
Talk by Sian Evans. From deposition to diapirism, salt has a unique impact on the stratigraphic evolution of a basin. Thick evaporite units deposited during ocean desiccation deform as a viscous fluid over millions of years, often resulting in profound structural complexity. Nature is more complex than we can imagine and the classic models of salt tectonics are unable to explain the diversity of structural styles and orientations that we observe. By using high-quality 3D seismic datasets from around the…Find out more »
Talk by Professor Andy Gale. The Cretaceous-Paleogene unconformity in England. Uplift and erosion related to the Icelandic mantle plume. During the late Cretaceous to early Paleogene, the present-day area of Britain and Ireland emerged from nearly total submergence by the chalk sea. What mechanism was responsible for this major marine regression? This is the third of a series of Earth Science-based lectures organised by DGAG in collaboration with other groups. As the Dorset County Museum is closed for refurbishment, 'til summer 2020, the lectures will…Find out more »
Includes a visit to Lander's Quarry for 10.30 a.m. We'll be shown round by Trev Haysom, a leading authority on the Purbeck Beds. We will visit both the quarry and the mine. Therefore participants should have a torch, hard hat, waterproofs and wellies. We will then go to the Square and Compass for lunch before a circular walk to Winspit and Seacombe Cliff and Quarry and then returning to Worth Matravers. Alan Holiday is leading the second half of the…Find out more »
Using seismic lines, gravity, magnetics, boreholes and pure conjecture to re-construct the history from the Lower Paleozoic to the Triassic. Talk by Dr Malcolm Butler. This continues the series of Earth Science-based lectures organised by DGAG in collaboration with other groups. As the Dorset County Museum is closed for refurbishment, 'til summer 2020, the lectures will take place in Committee Room 1 at County Hall. They will follow the familiar pattern of being on the second Wednesday of the month starting at…Find out more »
Starting from the main (lower) car park at 10.30 a.m. At this location there is an opportunity to view the Jurassic-Cretaceous unconformity and the basal Kimmeridge Clay. We will then work down the Corallian sequence as far as the Osmington Oolite at Bran Point. As usual, sign up with Alan or Kelvin if you'd like to come along.Find out more »
DGAG Residential weekend 2019 This year we are visiting the Glamorgan Heritage Coast (south-east Wales). Dates: Fri.3rd May to Sunday 5th May. Some may want to stay over Sunday night and do more on Monday. Leaders: John Scott and Kelvin Huff Come and view the results of Dinantian storms (Lower Carboniferous), the effects of the Variscan and later orogenies, Triassic desert wadis and lakes where early dinosaurs roamed. See the Triassic/Jurassic boundary and unconformities, a rare Jurassic rocky shoreline and…Find out more »

Lyme Regis Fossil Festival 2019, will be held from Saturday 4 to Sunday 5 May. To reflect current initiatives and concerns it is rebranded as the Earth, Sea and Fossil Festival and will have talks and events in the run-up to, and throughout, the festival reflecting this.
