Like most famous building stone, that on Portland was known to the Romans. (For Portland Building Stone at Portland Bill see also Portland Bill Field Guide)
Geological Introduction to the Isle of Portland Abide by their regulations and warning notices and, of course, always follow the instructions of the manager or guide. Take care not to fall down fissures in the Portland Stone and do not enter fissures or caves without the normal caving safety precautions.Īccess to Albion Stone quarries, mines or quarry works or factory is only possible with permission from the company. It is important not to hammer the chert in the Portland and Purbeck strata because of very dangerous.
Get of the way quickly and move to a place of safety away from the trackway or working location. Obviously keep away from motorised rock saws or other machinery. Large vehicles, JCBs etc, may appear quite suddenly on quarry tracks and quarry working floors, and it is not necessarily clear in which direction the vehicle is heading. In particular care taken to keep clear of heavy plant and machinery. High-vis jackets or tabards are normal in quarries. On the Isle of Portland safety helmets should be worn beneath cliffs and in quarries, and places where it is clear that rock has recently fallen should be strictly avoided. There are also hazardous cliff edges artificial cliff edges in quarries are sometimes less obvious than coastal cliff edges and should be watched out for. Like almost everywhere else on the Dorset coast care must be taken with regard to hazard of falling rocks. Some specific hazards with regard to geological study on Portland are mentioned here, but the subject is not covered comprehensively. Any field trip programme is the responsibility of the individual, or the leader or the organiser or the organisation. The objective is to provide geological information. In fact, it may be impossible to go to some places described. It may give geological guidance but it is not an itinerary or practical field guide or programme, nor does it represent advice to go to any particular place. This webpage is a description of certain geological features and many include photographs and descriptions of coastal scenary, cliffs and quarries.
