Note that the map uses combinations of terms that refer to: High, Moderate, Low and Variable calcium carbonate content. As a rule of thumb, these categories are based on the bulk mineralogy of the parent material. For example, high carbonate content would be expected for a chalk or limestone parent material type; low carbonate content would be representative of weakly, calcite-cemented sandstone. The term variable is used where the parent material comprises two or more distinct lithologies e.g. interbedded limestone and mudstone where it is not possible to clearly identify the precise parent type at any given location. Users should note that land management practices and natural weathering processes of parent materials play a significant role in controlling carbonate content (it has not been possible to factor in these influences within the scope of this dataset) and so the classes shown in this dataset should be regarded as wholly 'indicative'.
