Almost as soon as work began above ground, work also began on driving a tunnel northwards towards the sandstone face of Worsley Delph. |
In 1998 it recommenced extraction of sandstone from a quarry at Stancliffe in Derbyshire. |
The sandstone abraders were small, the largest being 8.23 cm in length and the smaller 3.94 cm. |
Stancliffe Stone wants to re-open the quarries to extract the high-quality sandstone they contain. |
Consequently, the foundation stone was quarried in Deadwood, and the sandstone for the walls came from nearby Hot Springs. |
In addition to the volcanogenic sedimentary rocks, there are lenses of limestone, quartzite, shale and sandstone. |
