On 14 July the annual community liaison meeting took place at Swanworth Quarry which is a DIGS site.

A group of interested people was shown round by Simon Clabburn, a director of Suttles who own the quarry. We were told about current extraction of the Portland Stone, which is largely used for aggregate in local building projects. The company hope to extend the quarrying operations to enable production for another 15-20 years providing a local source of stone and employment.

They also process and recycle inert waste which can be used for landfill. Once quarrying is completed in any part of the quarry restoration work takes place which has been going on since 1997.

The land is restored to limestone grassland which is nationally a rare habitat. Pictures here show the quarrying of Portland Limestone. The overlying Purbeck Beds have no commercial value at this quarry. Other pictures show the restored area. The restoration project includes a plan to retain a rock face exposing the upper part of the sequence. The geology is important as it controls the development of soils and the vegetation!

On 14 June some members of the DIGS group carried out conservation work at the Dorchester Road, Upwey cutting section.

This is not a DIGS site but part of the Bincombe SSSI. The rock was exposed during the construction of the Weymouth Relief Road (A354) prior to the 2012 Olympics.

This is an important site as it exposes the boundary between the Jurassic and the Cretaceous  (Portland and Purbeck Beds up to the overlying Wealden Beds).  

Some members visited our site at Vinney Cross on the A35 east of Bridport on 3rd May.

We cleared some encroaching brambles and weeds. Some nice examples of fossils were found in this good exposure of the Inferior Oolite very different to that seen between Burton Bradstock and West Bay.
