    Abstract

    Extensive glacial surficial deposits in Ireland prevent the identification of many karst features. Surface magnetic and resistivity geophysical measurements have been used to identify unknown karstic features. Two dimensional resistivity imaging has located an unknown 210-meter-long, 70-meter-wide and 25- meter-deep collapse feature in eastern Ireland beneath the surficial sediments. A resistivity survey over the Cloyne cave system in County Cork has identified the position of an unknown cave. A magnetic investigation of an infilled paleokarst collapse structure produced a 40 nanoTesla anomaly and illustrates that the technique can be employed in Ireland to locate unknown ones.
