Field Meeting Safety

Geology can be enjoyed by all but it is important to ensure everyone is safe.  All instructions from field event leaders must be followed as a requirement of taking part.  Leaders will advise of safety measures needed at each field event.

Risks Assessments

Risk assessments are carried out on all sites and field events by appointed safety officers and control measures to reduce risk are put in place.

Mine sites and quarries (whether active or derelict), coastal sites in particular can be dangerous places but any site visit has its dangers and risks. 

Special attention is needed for overhanging rocks and large boulders and rocks that can slip and move.  Quarries also often have large areas of muddy poisonous lakes and standing water is not often obvious. No one will be allowed near any overhanging rocks.

Equipment : hard hats, safety gasses, gloves, hard boots and highly visible tabards and coats must be used at all times in active quarry sites.  No one is permitted to attend without safety equipment.

Suitable footwear is needed particularly for sites with slippery surfaces.

Occasionally this is turned over, but even better good news is that it is also replenished by the company from the galena and lead secondary lodes exposed within the quarry. This was a joint field meeting of members of the Cheltenham Mineral Club and the Royal Geological Society of Cornwall.

Above is Little Johns Quarry within the China Clay District Of St. Austell, Cornwall.   The site was visited by the Society in 2015 and shows the vast size of the extraction process. The leader's advice given was to avoid soft ground, overhanging areas, other areas prone to slippage, static clay filled ponds and lakes, and heavy vehicles.  Please note the highest levels of the surrounding land represent as near as possible the natural original surfaces of the landscape which existed before the Clay pit was developed. 


The use of a "swiss army knife" is often used to show scale of rock matrix and crystal sizes. Here we see a highly altered   Kaolinised Granite with minor iron staining and Tourmalised veins

showing different phased stages of pneumatolysis of St.Austell granites in parallel structures.

Note the phenocrysts /crystals of kaolinized and partially kaolinized feldspars.

Mine Manager Paddy Bristow and Professor Colin Bristow are 7th and 8th from the left. Highly visible coloured hard hats,tabards and capped miner's boots are essential for everyone entering working clay pits.

Note the jointing and rounded blocks of the granite in the background. Members no doubt will be able to pick themselves out in the photo.
