Field Trip Description

Stancombe Quarry works within the Clifton Down Limestones of the Carboniferous Limestone Series. The strata are well jointed and dip north by about 20 degrees (forming the northern limb of the Broadfield Down pericline). In the south of the quarry the Triassic Dolomitic Conglomerate outcrops. The quarry is cut by several E-W trending faults/mineral veins from which small specimens of galena can commonly be found. The quarry itself produces about 1.5 million tonnes of limestone each year most of which goes to produce concrete or building blocks and some of which is used to make asphalt. The quarry opened in the early 1950’s.

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.
