Title: What is Pyrite good for?
Summary: Pyrite typically gets a lot of bad press being associated with death and destruction and being referred to by the somewhat derogatory term “Fool’s gold”. This talk will outline some of the reasons for the widespread dismissal of pyrite, before moving on to discuss some of my research at the University of Liverpool over the last two decades to demonstrate that pyrite is actually a very useful tape recorder of geological processes.

Lecture by Dr Amani Becker, NOC
Title: Energy River: Realising Energy Potential from the Mersey
Summary: As the need for greater renewable energy supply becomes ever more evident, I will present the findings from a review of the potential for increasing renewable energy generation in and around the Mersey Estuary. Dr Armani Becker will deliver the Liverpool Geological Society Lecture on Tuesday 19th October at 7.30 p.m. on Zoom

Lecture by Steven Millar, Tier Environmental
Title: Geology, Contaminants of Concern and Emerging Contaminants of Concern
Summary: Geology plays an important part in the assessment of the risk to human health and controlled waters when it comes to contaminants of concern that have been used by human activity in the past. However, as one contaminant of concern is no longer used, a new contaminant of concern emerges from the shadows. This talk will provide a brief background to the way geology can help or hinder when contaminants of concerns are identified.

Lecture by Professor Doug Mair, Dean of the School of Environmental Sciences, University of Liverpool
Title: How resilient will the Greenland ice sheet be in the face of Climate Change?
Summary: The Greenland Ice Sheet is the largest single source of global sea level rise. Warming air and ocean temperatures are increasing melting and iceberg calving. But how well can we quantify these changes and just how resilient might the ice sheet be in the face of climate change? Doug Mair presents an overview of 20 years of research into ice sheeting melting, ice velocities and iceberg calving to help understand this important scientific challenge.
Biography: Doug is Professor of Glaciology and Dean of the School of Environmental Sciences at the University of Liverpool Head of School of Environmental Sciences at the University of Liverpool. He is a glaciologist whose interests include the influences of hydrology on glacier dynamics and controls on ice sheet mass balance and volume change. He has investigated these using field-based measurements and the development of glacial process models. He has over twenty years of research experience in the Swiss Alps, the Canadian High Arctic and on the Greenland Ice Sheet. This research has been supported by grants from Natural Environment Research Council (NERC), The Leverhulme Trust, The Carnegie Trust and the Scottish Alliance for Geosciences, Environment and Society (SAGES).

Lecture by Anthony Clarke, Consultant Engineer
Title: Ground Engineering of the Liverpool Docks
Summary: The presentation will cover the history and method of construction of the Albert Dock and its river wall in 1840 when mechanisation was scarce. This will include why the dock was sited in this position of Liverpool together with the difficulties encountered with the ground and foundations.
Biography: Anthony is a Chartered Structural Engineer and a Conservation Accredited Engineer (one of 80 in the UK). He worked for 39 years at Curtins in their Liverpool office until March 2018 and is now an independent consultant mainly working on repair of Historic Buildings. His involvement at the Albert Docks started in 1982 when he was part of a team undertaking a detailed assessment of the derelict warehouses and continued through the development period and beyond. In total 30+ years’ experience working on these fabulous buildings. Other notable Liverpool projects have included both Cathedrals and most of the Museum listed properties together with John Rylands in Manchester. Since going into semi-retirement, he continues his private research on Victorian dock construction methods.

Lecture by Professor Richard Worden, University of Liverpool
Title: Carbon capture and storage: why we need it, what it is and what is holding it up
Carbon capture and storage (CCS) is a strategy designed to cut emission of the greenhouse gas: carbon dioxide. Carbon (dioxide) emissions result from practically all human activity from farming, through to cement manufacture, steel and other metal manufacture, as well as electricity, heat and power generation by burning fossil fuels. Carbon emissions must be cut to avoid catastrophic global warming which will otherwise result in sea-level rise by metres, loss of farmland, drowning of coastal cities, contamination of precious fresh water, changing global weather patterns, increased storminess and all the attendant human disasters that will result from any one of these consequences.
A major problem is that countries, corporations, and individuals are unwilling to change the way they function and live and are reluctant to face up to the long-term consequences of today’s actions. Note carefully, this is not just a question of building a few windfarms or even a few more nuclear power stations as cement, steel, and farming account for a massive proportion of carbon emissions. Carbon capture and storage is designed to help, though, by collecting CO2 from industrial point sources of generation such as power stations, and cement and steel factories, and injecting it deep underground, to be locked up forever.
Sound simple? In some ways it is, but there are serious factors holding up large-scale adoption of CCS. The good news is that there are precedents from a few oil and gas production companies that have already injected separated CO2, naturally present in some oil and gas fields, back into the sub-surface, over a period of 60 years or more. What is needed now is on a wholly different scale: all globally produced industrial CO2 must be separated from exhaust gas streams and piped or shipped to CCS sites.
In this talk we will cover some of the background but focus on the geology of carbon capture. We will also focus on the factors inhibiting large-scale adoption of CCS such as who insures, or assures, these projects designed to last for 10’s to 100’s of thousands to years, who pays for the very expensive capital and then never-ending operating costs for CCS. We may also touch on possible public resistance to CCS given that it will almost certainly cause micro-earthquakes, like shale-gas exploitation

Lecture by Tom Sharpe
Title: Mary Anning: monsters, myths, and misfortunes.
Summary: It has been said that more has been written about Mary Anning, the fossil dealer of Lyme Regis, than about any other geologist, apart from Charles Darwin. But how much do we really know? How much is speculation? And how much is myth that has developed through the uncritical telling and retelling of her tale over the course of two centuries? Separating the facts from the fictions about Mary Anning can be challenging, but her story is a remarkable tale. This talk will examine what we know of the life of this extraordinary woman, her famous – and less well-known – discoveries, and her part within the wider network of the developing science of palaeontology in the early nineteenth century and will seek to dispel at least a few of the Mary myths.
Tuesday 7th December 6.30 – 9.00 p.m.

Title: Jelly volcanoes
Tuesday 4th January 2022
Members’ Evening at The Athenaeum
Stephen Hurrell “Quetzalcoatlus northropi in a reduced gravity”
Aeronautical calculations seem to show that the largest pterosaurs would struggle to achieve powered flight. Is it possible that these Cretaceous giants flew in a reduced gravity?
Geoff Gilchrist “Llangollen”
The area covered in this talk is based on the 1: 50 000 BGS map sheet 121 (Wrexham): Solid & Drift map. The geology ranges from Ordovician to post glacial. There is a strong relationship between the geology and the physical landscape with some unique features. The Carboniferous outcrops and associated landscape features are quite dramatic and some of the post glacial features such as glacial diversions involving deeply incised meanders are unique.
Peter Williams “A dud spud in Kitkiojarvi”
A talk about one of the oldest objects in the solar system – and one of the youngest. And for those that like a puzzle, here are 4 dates for you:
4.56 billion years ago
1 000 000 years ago
Talk about the muonionalusta meteorite

My favourite outcrops
Outcrops can tell a wonderful story of Earth history, and this talk will discuss a few favourite examples I have visited to do field work, from North America to South Wales and across a range of geological ages and events.
