Stonepark Hyperspectral Drillcore Data

Thiele, S. T.; Kirsch, M.; Madriz Diaz, Y. C.; Gloaguen, R.; El Alami, S.; Cecilia Contreras Acosta, I.; Saffi, H.


This hyperspectral drillcore dataset (shed) contains 14 drill holes, totalling 389 boxes that cumulatively contain 2513 meters of scanned cores. Hyperspectral data is stored in the widely used ENVI format (.dat and associated .hdr files), which can be opened using e.g., napari-hippo (GUI) and hylite (python). The whole directory structure is compatible with hycore, for easier out-of-core processing and visualisation.

These hyperspectral data and associated visualisations can also be viewed interactively here.

The scanned drillcores were selected to cover the main mineralised intervals and key stratigraphic horizons, sedimentary facies, igneous intrusions, brecciation and alteration zones present at Stonepark. These include the Knockroe Fm and Knockseefin Fm, the Lough Gur Formation, the Waulsortian Limestone Formation, and the Ballysteen Formation (Argillaceous Bioclastic Limestone). Drillcore selection was further based on the availability and accessibility of drill core and sought to capture the variations both laterally and vertically, in consultation with geologists from Group Eleven Resources.

These data were acquired as part of the Horizons Europe project Vector. We would also like to acknowledge Group Eleven, for providing access to core material and their support during data acquisition.
