Description: Karst is a term used world-wide to describe the distinctive landforms that develop on rock types that are readily dissolved by water. In Ireland, karstification mostly occurs in limestone regions. As approximately half of the Republic of Ireland is underlain by limestone, karst is a significant aspect of the Irish environment. There are many kinds of karst landforms, ranging in size from millimetres to kilometres. For simplicity, these landforms are grouped into nine main types in the National Karst Landform Database. These are: borehole, cave, dry valley, enclosed depression, estavelle, spring, superficial solution features, swallow hole, turlough.The National Karst Database consists of point features, locating the centre (or,in the case of a cave, the entrance) of the karst landform,and records details of the landform’s dimensions and functioning. The database was developed by Morgan Burke in 1999. Features are added to the dataset through periodic live updates.It is important to note that it is NOT a comprehensive database and represents only areas that have been mapped by GSI, or third parties whose data have been processed. Although we try to ensure the information is as reliable as possible, the GSI takes no responsibility for the accuracy of the data or for decisions made on the basis of using the data. Due attention must be paid to the location accuracy given with each well record. Digital files are live-updated periodically and users are responsible for obtaining the latest version of the data.There are 17 data published fields (designated in square brackets below, []). Not all records have data associated with all fields and, for many of the records, only some of the fields have values.[FNUM]: GSI's number for karst feature.[FTYPE]: karst feature type –one of eight main types: borehole, cave, dry valley, enclosed depression, spring, superficial solution features, swallow hole, turlough.[FNAME]: karst feature local name, such as a local spring name.[TOWNLAND]: Townland name.[COUNTY]: County.[GRID_ACCUR]: Spatial accuracy of the Grid Reference, in metres/kilometres.[COMMENTS]: General comments.[KFSOURCE]: Source of information for karst feature, if not from GSI studies.[COMMENTS_1]: Comments on geological setting, including stratigraphy.[SP_TOWNLAND]: Townland name.[SP_COUNTY]: County.[LITHOLOGY]: Dominant limestone composition: Dolomite; Limestone, muddy; Limestone, clean (>=90% CaCO3, bedded); Limestone, cherty; Limestone, clean (>90% CaCO3, unbedded); Limestone, other; N/A).[STRATIGRAPHY]: [EASTING_ITM]: Easting, six figure Irish Transverse Mercator Grid Reference.[NORTHING_ITM]: Northing, six figure Irish Transverse Mercator Grid Reference.[EASTING_IG]: Easting, six figure Irish National Grid reference.[NORTHING_IG]: Northing, six figure Irish National Grid Reference.
