| Lineage | The soil map is an interpretation of the superficial and solid geology maps made by the British Geological Survey (BGS) in 1998. The superficial deposits were kept entirely and where the class "non-superficial" occurred it was clipped to the solid geology in order to have the entire land mass of the Falklands covered by interpreted soil types. The solid geology formations were simplified into the following lithological categories: sandstones, sandstones with siltstones and mudstones, mudstones and siltstones, quartzites, tillites and mudstones, granite and gneiss. In order to calculate the Soil Organic Carbon (SOC) for each simplified lithology class, a quarter of the total area of that lithological layer was considered as peat. This was a personal choice but based on a reasonable guess of what occurs in reality. Indeed field surveys will allow this estimation to be reassessed more accurately. Cape Meredith complex was the only lithological class that was not considered peaty because it is too small. Similarly, coverage of peat and other soil types (as percentages) were also estimated for all the superficial geology classes. These soil types cannot be mapped as no soil survey has been carried out in the Falkalnds to allow surveyors to draw boundaries between types. Old auger bores, 186 in number, collected in a minefield feasibility study carried out in 2006, were used in part as ground truthing. The main problem with the auger bore datasets is that they were concentrated in the minefield areas and, therefore, despite giving a good representation of soil types, had a limited spatial distribution and use. Other people's analyses were taken into consideration (e.g. DOA soil samples) but these had very little information about soil types and geographic coordinates were approximate in many sampling locations. |
