The GSNI core store contains around 20 km of rock core from boreholes across Northern Ireland and conserves cores and rock specimens as an archive for research, industry and educational use. A number of cores come from boreholes that were from 1949 to 1960 in a program of drilling carried out by GSNI shortly after the inception of the survey in 1947. The boreholes were mostly drilled in search of coal, gypsum/anhydrite or perlite in the areas around Stewartstown, Dungannon and Coalisland in Co. Tyrone, Newtownards in Co. Down and Ballycastle and Sandy Braes in Co. Antrim.

We would like to thank the relatives of Patrick Hall for taking the time to show us this material and allowing us to photograph the archive for use in this article.
