Date and Time



Tintern Quarry, Chepstow NP16 7JN

Field Trip Description

Tintern Quarry exposes the thickest section of Carboniferous Limestone in the area. The quarry face itself is some 400 ft high, with several benches and haul roads. In the base of the quarry is the Lower Dolomite which has some good dolomite crystals in it. A forestry track circling the quarry provides safe and easy access to a full sequence from Lower Dolomite, through Crease Limestone, Whitehead Limestone, Lower Drybrook Sandstone, Drybrook Limestone and Upper Drybrook Sandstone.

The junction between Lower Dolomite and Crease Limestone is uncertain in this area as dolomitisation has affected both units to a high degree. The Whitehead Limestone is variably porcelaneous, mudflake breccia and dolomitic mudstone, with many stromatolites and a significant palaeosol at the top. Lower Drybrook Sandstone is a coarse gritty sandstone but there are some curious features exposed in the track cutting that the leader will invite suggestions about. Drybrook Limestone is partly oolitic, partly porcelaneous and has palaeokarst within it (nearby is an area of limestone pavement which we could visit if we have time).

Meet at 10.30 am at Tintern Quarry (SO 550 984) Please wear stout walking shoes and suitable outdoor clothing. Bring your own packed lunch.

Important Notice: Bath Geological Society Insurance

Each person attending a field meeting does so on the understanding that he/she attends at his/her own risk. The Bath Geological Society has Public Liability Insurance Cover for field and indoor meetings, but Personal Accident Cover and Personal Liability Cover remain the responsibility and personal choice of the participant.

There may be an element of appropriate cover included in house insurance or in travel insurance: although Bath Geological Society activities are not particularly dangerous members are advised to check whether exclusions apply to activities in which they plan to participate in case they wish to arrange further cover. An annual travel insurance may be the best solution for any member who regularly attends field events: this again is a matter of choice.

Please note however that all members participating in overseas events will be required to have travel insurance for the duration of the event: this is so that participants are covered for Medical, Repatriation and Personal Liability expenses. The Personal Accident element remains the personal choice of the member and again members are advised to check exclusions so that they can make an informed decision about the cover they want.
