Excerpt from Memoirs of the Geological Survey of Ireland: The Geology of the Country Around LimerickThe recent survey had for its Object the mapping of the glacial drifts and other superficial deposits which were not included within the scope of the original survey. A general revision of the boundaries to be assigned to the rocks below such deposits was not attempted, but in certain cases, where fresh observation showed the need for an alteration of the line between the limestone and the igneous series, a new line was drawn upon the map. Mr. Kilroe, who has written the ac count Of the solid geology Of the area, believes that many of the lavas dealt with are intrusive in the masses that sur round them, but this does not necessarily remove them from contemporaneity with the general volcanic action that charac terised the Limerick district in Carboniferous times. A volcano of the explosive type may thus show, when dissected by denudation, beds of tuff and ash, cut by those parts of the lavas that never reached the surface.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
