Methane Derived Authigenic Carbonate (MDAC) Aragonite Cemented Quaternary Hardground from a Methane Cold Seep, Rathlin Basin, Northern Ireland: δ<sup>13</sup>C and δ<sup>18</sup>O Isotopes, Environment, Porosity and Permeability

Methane Derived Authigenic Carbonate (MDAC) Aragonite Cemented Quaternary Hardground from a Methane Cold Seep, Rathlin Basin, Northern Ireland: δ<sup>13</sup>C and δ<sup>18</sup>O Isotopes, Environment, Porosity and Permeability

A block of sandstone retrieved by divers from near Rathlin Island, Co. Antrim, Northern Ireland, represents an aragonite cemented sand formed during the Quaternary. Strongly negative δ<sup>13</sup>C of the aragonite cement (−50 to −60‰ δ<sup>13</sup>C) indicates that the hard...
