Control of algae with barley straw
[摘要] This report describes the 2012 version of the GB3D National Bedrock Fence Diagram produced by a mixture of EA funded contracts and BGS National Capability projects between 2009-12. The fence diagram, comprising the GB3D_v2012 dataset, is the subject of this report and is now available in a variety of formats from the BGS website as free downloads. It complements the existing 1:625 000 scale mapsheets published recently utilising the same colour schema and geological classification. The fence diagram currently covers England, Wales, Scotland and the Isle of Man. It is envisaged that this dataset will form a useful educational resource for geoscience students and the general public and also provide the bedrock geology context and structure for national, regional, basin-wide and catchment scale studies.
