The Mines of Shropshire
Shropshire's rich geology hosts many exploitable minerals and there is a long history of mineral mining and six coal fields in the county. In this talk, learn how ores and coal formed, how the mines changed the Shropshire landscape and settlements and what happened after they were worked out and abandoned.

Ancient Vulcanism in Shropshire and Mid Wales
Did you know that Shropshire and Powys are home to numerous ancient volcanic outcrops, giant intrusions and rare igneous rocks, such as picrite, used by Paleolithic tribes to fashion axes? Join us for this, the fifth talk in Sally Green’s fascinating annual geology series, to hear how processes of ancient vulcanism from different eras have shaped our landscape and affected the economy in our county.

The Ice Age in Shropshire
Shropshire stands right at the southern end of the last Ice Age ice cap, which had a profound effect on our landscape.
Sally Green talks about some of the dramatic climatic changes in the last two million years and the effect of ice movement on the formation of our county’s topography.
This is a follow-up evening to Sally’s highly popular talk on Shropshire Geology in 2021.

The Quarries and Buildings Stones of Shropshire
After a brief recap of her original Geology talk, Sally goes on to explain the importance of the base geology to the built environment in Shropshire.
Every village would have had its quarry in the past and so the buildings 'grow' from the rocks and bricks from the clays.
