Peak Minerals

The Earth’s mineral resources are finite, and dwindling. The concept of “Peak Minerals” provides a framework for understanding the economic, social and environmental trajectories of particular mining industries whereby ever increasing production leads to extraction of the higher grade and more easily mined resources leaving ever lower grade, less easily mined (more expensive) resources behind. In such a scenario, for a given material in a given area (e.g. country, continent, planet) production may peak and subsequently decline as grade of the resource decreases and exploitation costs increase. This lecture will discuss the metals gold, lithium and copper, and the non-metal phosphorus in terms of when peak production may occur and the factors that may bring forward or push back peak – and the potential consequences for our species.

Dr. Chris Hunt:The Environmental Geology of Prehistoric Malta

The first European civilisation arose in the Maltese Islands and lasted for more than 2000 years. How, on these arid, rocky, restricted islands, with few natural resources, did they do it – and why, eventually, did it fail? Coastal plain sequences, ancient soils and geophysics provide the evidence for how the Maltese Temple culture was born, flourished, and eventually perished.

Geothermal Geology: Teaching a New Dog Old Tricks

Dr David McNamara is a former PhD graduate of the University of Liverpool who has since built an industry and research career in the internationally growing geothermal sector. David spent over seven years working for New Zealand’s Crown Research Institute ‘GNS Science’ where he worked to adapt oil and gas techniques to geothermal application. David’s work centres on understanding the flow of geothermal fluids which includes characterising structural networks, and understanding the nucleation and growth of scaling minerals in geothermal reservoirs in New Zealand, USA, Nicaragua, Indonesia, Ireland, Uganda, Iceland and now the UK. David is now back in Liverpool as a Lecturer in the School of Earth, Ocean and Ecological Sciences.

Lanzarote: A Geoconservation & geotourism perspective

Lanzarote is a unique island recognised by UNESCO as a global Geopark and Global Biosphere. This talk will introduce the geology but also look at the contribution of one man to the geoconservation of the island and his effect on geotourism.

19th Jan Dr.James Lea, University of Liverpool:

Now you see them, now you don’t: Greenland’s vanishing meltwater lakes

Dr James Lea (University of Liverpool) talked about recent advances in mapping and understanding the behaviour of the thousands of meltwater lakes that form on the Greenland Ice Sheet every summer, identifying instances of their rapid drainage through fractured ice and what this means for the ice sheet.
