Nov 06, 2013 (A Wilson) - A grab sample of marble collected by the OGS returned an analysis of 0.9% non-carbonate carbon. No anomalous or otherwise significant metallic values were found within the clastic metasedimentary blocks. Much of the crystalline limestone in the Township of Lutterworth constitutes a veritable marble. This limestone would yield excellent lime, and would afford a fine material for building stone. It is, however, rather coarse-grained for very fine work, or for statuary purposes. The marble has not been tested for its suitability as a dimension stone.
