The rock samples collected from the site of the proposed quarry extension at Maddoxtown, Dunbell Big townland, were analysed at a recognised Irish laboratory. The rock samples were prepared for analysis by the laboratory and each was analysed for 46 elements, including calcium and magnesium. The calcium and magnesium content determines whether the rock is dolomitic. The samples were analysed using a modern spectroscopic analytical technique, ICP-AES — inductively coupled plasma atomic emission spectrometry. This analytical method is accurate to 0.01%. It is accepted that best practice analytical procedures were followed, including repeat analysis of standards and analysis of blanks.
