Geology Workshops |
|
Students investigate the remarkable geological structures at Apes Tor then analyse and evaluate their data. They continue to study the structures on the Hill and within Salt’s Level. At home, they write a plan for further investigations that could be carried out on, and under Ecton Hill. This activity covers all four of the requirements for an assessed investigation. |
|
Calculate the concentration factor for copper ores at Ecton. Demonstrations modelling the processes by which mineral deposits have been formed – rising fluids versus descending ones. A mine visit to look for evidence of the origin of ores in the mine. |
|
Observations of rock characteristics are made in the field and the likely “stand-up time” for an unsupported mine tunnel are calculated |
|
.Students learn or revise how to identify relevant minerals at the Centre. The leader establishes the concept of the water table. Students gather evidence from the mine visit for a) secondary alteration of minerals and b) levels of water table in the hill. Follow up; using standard diagrams of enrichment of ore bodies. |
|
In Salts’ Level, students observe, discuss and hypothesise about the origin of flowstone and stalactites. They model the chemistry of limestone weathering in lab apparatus and discuss the origin of limestone in general. |

|
This is a follow-up sheet for School use and outlines the things that students might look for while visiting Ecton or could be applied to well-known mine sites during follow-up work at school. |
|
Mixtures of minerals are separated using simple techniques based on density differences and which model the buddles and jigs once used at Ecton. Students discuss the impact of technological change, the demand for copper and world copper markets to decide whether or not a deposit is worth mining. Will Parys mountain in Anglesey reopen? |
|
Students are asked to plot given values of copper and lead concentrations on a map of an imaginary area. They draw contours of equal concentration and then assess the resultant patterns |

Please read these summaries before filling in the form to request a booking for your group. You can obtain more details about the workshop by clicking on the heading. Note that most groups wish to visit the mine, in Salt’s Level, which takes about 1 hour. The mine visit features in most of the workshops, either to test hypotheses set up on the surface, or to gather data. Once you have agreed your itinerary with the EHFSA, you will need to download the sheets for the appropriate workshops from the website (shown in the BLUE BOXES). At the very minimum, sufficient student sheets should be printed for members of the party covering the topics chosen for the day’s visit. |
