Cornwall Geoconservation Group 
A Committee of the Royal Geological Society of Cornwall
Cornwall Geoconservation Group (CGG) is a volunteer organisation of professional and amateur geoscientists and mining engineers. Its role is to raise awareness of the county's geodiversity (i.e. its rocks, minerals, fossils, soils and landforms) and to provide advice on their geoconservation. It has a responsibility for designating and maintaining County Geology Sites (CGS) and providing advice to Cornwall Council on planning issues that could have an impact on geodiversity. CGG is a formal consultee on planning issues.
