Geology

British Geological Survey (BGS) Viewer

The link below will take you to an overview of the BGS Viewer mapping system. By clicking on the image of the map or on the ‘Open Geology of Britain Viewer’ the interactive map will be opened. Zoom in to an area of interest and click the Geology Key on the left hand side to interpret the map. Clicking on a geological feature within the key will open a new page with general information about this type. This map also allows borehole scans, 3D borehole model cross sections, and earthquake data to be viewed. These can be accessed by clicking the tabs at the top of the map.

This could be a useful tool in a geography lesson. The 3D model function is an engaging tool which demonstrates the composition and types of rocks present within a chosen section of earth. Additionally, the borehole data files found lower on this page can be used to support this lesson as they provide real examples of borehole data taken on the A9. The teacher could expand into why it is important for infrastructure projects to explore the geology along the route corridor before finalising design – for structural and financial security (to avoid soft / sinking stratas) and to avoid sensitive areas (ecological, geological or hydrological / flooding).

Soils Scotland Map

The link below will take you directly to Scotland’s Soils interactive map. The types of soil can be interpreted and selected by clicking on the ‘Show map legend and layers’ link at the top of the map. Alternatively, clicking on a layer will produce a detailed table below the map with information about the selected soil.

Borehole Data Files

Below you will find real examples of borehole drill data derived from sections of the A9. These files contain the descriptions of strata types found at different depths of the borehole. Within the folder is a file named ‘Notes on Exploratory Hole Records’. This technical guidance provides lots of general information including the methodologies that can be used to sample soils and detailed descriptions of the types of soils and their usual characteristics.

These files could be used to support a geography lesson. Pupils could be asked to look at the borehole data samples and describe the characteristics of the strata present. The ‘Key to Borehole Records’ section (tiled images of types of soils/rocks) within the Notes on Exploratory Hole Records file should be used as a legend to explain the cross sectional data within the real examples.

National Library of Scotland

The link below will take you directly to the National Library of Scotland’s online mapping collection. Follow the link ‘More about this resource’ that explains the best way to access and view the variety of maps on offer.  This is a useful resource when assessing a particular site.  By taking into consideration a site’s history will help to inform decisions about the site’s future use.

Ground Beneath Our Feet

Ground Beneath Our Feet is an Academy 9 activity used during the Academy 9 Roadshow. It aims to investigate the geology along the A9 and describe what a geologist does.  This is then linked to the process of designing and building a road and how the geology affects decisions made.

Geology FAQ’s

The Geology FAQ’s below have been developed by a geologist to answer some of the main questions pupils may have with regard to what a geologist does, what the existing ground is like on the A9 and how it affects a project such as the Dualling of the A9. The FAQ’s also includes links to further information in answer to certain questions.
