The ultimate core tray logger simultaneously collecting the 4 major rock logging data sets

Core is expensive to collect so you need to get the maximum information out of it.
Don’t let any meaningful data go by.

  • Key Features

    • Collecting the 4 major rock logging datasets simultaneously -Hi-res images, XRF, ASD, Mag Susc
    • Compact and portable core tray analyser - Ideal for drill sites and core sheds
    • Automatic operation - Saving you time and money
    • Fast data collection - Quality, multiple datasets in minutes
    • Datasets coregistered by downhole depth - Standardised measurements for a uniform database
    • Digital archive - Ready for big data processing

Core is expensive to collect so you need to get the maximum information out of it.  Don’t let any meaningful data go by.

Within minutes, the Geotek Boxscan allows you to automatically and simultaneously collect the 4 major rock logging datasets:

  • Chemistry by XRF Olympus Vanta,
  • Mineralogy by ASD,
  • Mag susceptibility by Bartington
  • High resolution digital images with the Geotek Linescan V camera

The Geotek software instantly co-registers the data- points by down-hole depth. The data is in one format and ready for seamless uploading into visualisation packages and big data processing.

With the Geotek high resolution linescan camera you have a digital image free from spherical distortions down to 25um on wet or dry core, which is a far higher resolution with a hand lens. Together with the other datasets of mineralogy, chemistry and mag susc, they link into:

  • Applying initial petrological and mineralogical interpretations
  • Identifying rock facies and metamorphic zones
  • Observing the rock matrix, inclusions, veins and deformations in the rock
  • Alteration zones
  • Geochemistry

  • True Colour Separation

    The Geotek Geoscan V line scan camera has one massive c.5340 pixel CCD. Incoming light is passed through a set of red, green, and blue filters to produce true independent colour separation. Averaged image data can be converted to these RGB values and saved in a separate file to facilitate quantitative comparisons between cores and other down-core measurements.

    Single lines of image data are collected sequentially down the core. Line-scan images are far superior to area camera images because they do not suffer from uneven lighting, spherical distortion, montage or “stitching” effects. The entire image is suitable for calibrated sub-millimetre image analyses.

    High Resolution

    Images can be collected over the full core width between 100 and 1000 lines per centimetre, corresponding to 100 and 10 micron pixel sizes, respectively. Images are output as 48-bit RGB TIFF images but are quickly and easily converted to JPEG or other formats as required. Each Geotek core section image has a companion XML metadata file, containing important metadata pertaining to the core section and imaging conditions. A ruler can be generated next to the image, depicting either depth in core section or depth in core.


    The camera is factory-calibrated and a standard photographic 18% grey, or 90% white cards are used for field calibration, enabling images to be qualitatively or quantitatively compared to each other.

    Advanced Camera Control

    The Geoscan V has automatic focus, aperture and light control routines built in to the Geotek imaging software. The software now guides the user through the camera and lighting set-up to optimise image exposure consistently and simply.

    Three Minutes per Metre is normal scan time for standard (50 micron) resolution,for the higher resolutions time increases.

  • The Boxscan has been ruggedly designed for field work and can incorporate your existing pXRF. It has multiple sensors including magnetic susceptibility, XRF and laser profiler delivering high resolution core surface height measurements. These datasets are depth-correlated with high resolution true colour dry core images and cross-polarisation for wet core photography.
