Our present understanding of the geological origin of the mineralsprings waters, briefly stated, is this: The region eastward of thefault is covered by a thick layer of impervious shale, which is verymuch broken up in the vicinity of the Hudson river. Where theseshales are most disturbed and broken, the percolating meteoricwaters have penetrated and have traveled along the dip of theunderlying rock through the limestone beneath where as a resultof secondary changes there taking place in the limestone, they haveacquired carbon dioxid and when saturated with this gas havegained an increased solvent power which has enabled them to takeup various soluble salts from the rocks through which they havepassed.
