Photos from the recent field trip to Ireland

The Bristol SEG hosts a series of lectures, fieldtrips and seminars aimed at engaging students, academics and industry professionals in discussions about economic geology and the mining industry. See below for photographs from the recent field trip to Ireland, as well as posters from previous guest lectures.

Life as an Exploration Geologist - Lucy Crane - Altus Strategies

Following in the footsteps of the 'Father of English Geology', William Smith

The Bristol SEG enjoyed a beautiful, sunny if quite chilly, February day exploring the historic economic geology sites of Somerset through the eyes of William Smith, the 'Father' of English geology.

2015 marked the 200th anniversary of the publication of the first geological map of England and Wales, drawn by surveyor William Smith. In celebration of the bicentenary, the University of Bristol prepared a guided field tour of some of the key localities of William Smith's life and work in the Somerset area between 1791 and 1819...

Diamonds: A Window into Deep Mantle Processes

Our very own Head of School, Professor Mike Walter, entertained a large undergraduate and postgraduate audience with his presentation on his research on the fascinating world of diamonds and what they can reveal about deep mantle processes.

WHAT LIES BENEATH?! Fieldtrip to the Redcliffe Caves, Bristol

On a cold but crisp winter's evening the Bristol SEG were guided around the Redcliffe Caves by local caving expert Alan Grey. The caves stretch for over 9 acres beneath the city and have an illustrious history at the heart of Bristol life.

After meeting us outside the Ostrich Inn, Alan took us around the wharf to the unassuming cave entrance - but we weren't allowed in straight away! First we went on a walking tour of the Redcliffe area where Alan explained the rich history of the wharfs and the various African goods traded there by local merchants...

Exploring the Arigna Mining Experience with our guide, a veteran coal miner who worked at mines in the area. The height of the timber pillar is all the miners had to work in while extracting the coal.

Discussion of the upper geology at the Giant's Causeway. On top of the well-known columnar basalts are more randomly-orientated entablatures, which form due to the effects of water.

The group were talked through the core log that had been drilled for the Tara exploration department, and how the different lithologies affected and preserved mineralisation.

Bristol SEG Chapter 2017 Launch Event

Guest Speaker: Lia Ituarte

Join the Bristol SEG for their first talk of the 2017-18 academic year!

President of the society, Oliver Higgins, will be presenting an introductory talk about the society, including last year's news and upcoming field trips and talks.

Lia Ituarte, Bristol Research Fellow in Mineral Systems, will then present her talk on working in the mining industry and links to academia.

Don't forget to bring £5 to sign up to the SEG society for the year, giving access to all guest lectures and field trips!

Tellurium Tomorrow: Solar Power, Supply, Demand,

and Waste of a Rare Material


Guest Speaker: Dr. Dan Smith, University of Leicester

Tellurium is one of the rarest elements on the Earth, and has seen demand skyrocket in recent years due to its use in solar panels. Dr. Dan Smith will talk about the element's discovery, extraction and uses, as well as how we are wasting this precious metal.

This event is for members only, but membership can still be purchased on the door, and will guarantee access to all the SEG's future events and talks!

A big thank you to all of the Oxford and Cambourne SEG members who came out with us on the trip!

The first stop on the trip was the Rosevale mine. This privately owned mine is undergoing detailed restoration, and we were lucky enough to be given a private tour!
