CSF (UK1.7)

The Core Scanning Facility (CSF)

The Core Scanning Facility (CSF) hosts four high-resolution core scanners for core imaging and non-destructive core analysis. Whole, split, plugged or slabbed rock and sediment cores, up to 1.5 m in length and 15 cm in diameter, can be continuously and non-destructively scanned with these capabilities in order to:

• provide information on the geophysical, geochemical, mineralogical, and structural properties of the core
• record core quality and fundamental variations downcore
• take high-definition optical, near-infrared (NIR), ultraviolet (UV) and radiographic images.

The CSF can facilitate research and add to drill core data acquisition and exploration procedures, greatly reducing the time, cost and need for destructive sampling. It can enable scientists to target specific areas of interest for analysis by other means and thus, maximise the value of core by preserving a digital record of the core beyond its physical lifetime. As part of the service, the CSF provides equipment support for all components and system parts, as well as information on how to process and manage the core scanning data.

The CSF is located within the British Geological Survey and can provide assistance with integration of data and interpretation. We are situated on the same site as the National Geological Repository (NGR) which contains over 600 km of onshore and offshore core. Interpretive work through PerGeos software can be used to characterise porosity, fractures and features within 3D CT imagery. XRF can be custom fit, processed and output based on the scientific questions asked. 2D XRF maps can be rendered and tailored to needs. Integration of data types can be assisted with, as well as access to processing software. 

The core scanning facility offers access to four state of the art core scanners. Data from each machine can be integrated together and offer a unique insight into a rock core. Combining geophysical, geochemical, structural and imaging capabilities makes multi-faceted characterisation possible. The high throughput of the core scanners allows regional scale geology to be characterised on a cm scale, as well as allowing detailed interrogation of sites of interest. The core scanners represent a powerful tool of discovery for large volumes of rock, facilitating site selection for sub-sampling and directing further work in a meaningful way.
