Abstract:

At several places in the Cork Syncline, in particular close to the northern Devonian-Carboniferous contact, closed negative gravity anomalies occur. These range up to 4 mgal amplitude and cover about a square kilometre. The cause suggested is decomposition of the Carboniferous Shale and solutioning of the Carboniferous Limestone to a depth of 180 m below the surface, the cavities being filled with the insoluble residue of the limestone and shale together with other washed-in material. The age, by comparison with similar known occurrences in Ireland and England, is probably Tertiary. Author
