The problem


Central to all geological characterization, including the interpretation of vast amounts of geophysical data, are geological observations made on drill core and chips.


Two factors that impede the quality and reliability of these observations are:

  • inconsistencies of visual observations between observers

  • a lack of tools to efficiently reconcile the observations against photographic records


The solution


Core Profiler is a software-based logging tool that builds a scaled continuous image of drill core from hand-held core tray or core split photographs. The Core Profiler software allows logging of geological and geotechnical information directly from the scaled image. Logging sheets, data dictionaries, reference images and links into the reference library are user-defined and can be set up to follow standard mine conventions. Images and data can be exported to the software packages most commonly used by mine sites.


The intial development of Core Profiler was funded by the Australian Coal Association Research Program (ACARP project C15037). Since then, Core Profiler has been extended to provide:

  • Out of the box support for the Australian Coal Logging Standard, although the logging sheets can be easily customised for use by the metalliferous industry

  • Support for oriented core measurements (alpha, beta, dip, dip direction).

  • Support for fracture frequency, RQD measurements and stereonet analysis


Developed by the CSIRO, Core Profiler is commercially distributed globally by Datamine.
