The newest generation of multi-sensor drill core scanning technology


DMT´s latest development in core scanning technology is a modular multi-sensor device that combines analytical sensors to measure chemical and mineralogical drill core composition in real-time. Additionally, smart machine learning techniques are used to classify the core samples into geological domains like lithologies or alteration zones. The perfect tool to support geologists and speed up decision-making.


ANCORELOG - Integrate your geological expertise with the newest generation of innovative drill core logging technology.

ANCORELOG can be modularly equipped with an array of different analytical sensors enabeling continuous XRF profile scanning, hyperspectral imaging (VNIR – SWIR), high resolution RGB and UV scans, time-gated Raman, and LIBS. The modular approach helps to adapt the equipment to your project-specific requirements. The analytical sensors measure mineralogical and geochemical drill core compositions. Additionally textural, structural, and geotechnical features are derived from high resolution images.

What do we offer?


ANCORELOG is designed for the use by geoscientists. Both, the data acquisition, and the data processing workflows are optimized for an efficient and friendly use experience. The easy use and high scan rates combined with real time processing can cover the daily production rate of a common drilling campaign.


Our team will help you to define the best sensor combination to meet the specifics needs of your project. A knowledge transfer is given to your professionals in the use of ANCORELOG, including the implementation of predictive models. Depending on the needs of your project, it is possible to buy or rent ANCORELOG. DMT´s global presence through our international offices provides on-site service, technical and commercial support.

Laser Line Scanner

Laser Line Scanner

  • Core Boxes are scanned with a laser line sensor resulting in a 3D point cloud of the core box.
  • The XYZ coordinates for the optimal scan path are derived from the point cloud with a sub millimetric precision (0.055 mm).
  • The detailed 3D point cloud allows sequential, continuous measurement of drill core with the different sensors.

RGB Line Scan Camera

RGB LinescanCamera

  • Assures constant light conditions and distortion-free geometric images.
  • 16k pixel resolution per line. 40 pixel/mm in standard mode, up to 160 pixel/mm in high resolution mode.
  • Framerate: 2500 fps

Hyperspectral imaging (VNIR – SWIR)

Hyperspectral imaging (VNIR – SWIR)

  • Identification of minerals based on their absorption and reflection features in the VNIR – SWIR spectra.
  • The hyperspectral imaging (HIS) camera is used continuously on all drill core samples.
  • HSI camera provides high resolution images to support spatial distribution of classes and textures.
  • Scan speed of 2 cm/s and a resolution of 4 pixel/mm in SWIR

X-ray fluorescence (XRF)

X-ray fluorescence (XRF) 

  • ANCORELOG uses J&C Bachmann’s Texas XRF sensor.
  • Elements with atomic number bigger than 15 are identifiable.
  • The XRF sensor does a continuous measurement along the scan path at a variable speed and a variable measurement integration time.

Timegated® Raman technology

Timegated® Raman technology

  • Mineral identification in selected regions of interest
  • Timegated® Raman compared to conventional Raman technology avoids interference from fluorescence signals that hides the Raman signal
  • Able to identify a wider range of minerals and is not limited to minerals with O-H bonds

Laser Induced Breakdown Spectroscopy (LIBS) Sensor

Laser Induced Breakdown Spectroscopy (LIBS) Sensor 

  • Elemental identification in selected regions of interest
  • LIBS is characterized by its good detection of light elements (atomic number smaller than 15).
  • Is useful to identify lithium, magnesium, and aluminum among others.
