We characterize your geomaterial by thin-section observations. We carry out petrographic analysis of different rock types (carbonates, siliciclastics, metamorphic, plutonic, etc) following NF EN 12407 standards.

According to your thematics, they include the description of grain types, textures, structures, fracture diagenesis, alteration, a visual estimation of mineralogical phases and the characterisation of porosity (quantified by colour thresholds).

Applications to the fields of:

  • Oil & Gas
  • Geothermal
  • Deep Storage
  • Geotechnics
  • Quarry


We carry out qualitative and / or semi-quantitative analyzes of the minerals constituting your soils and materials (XRD).

Applications to the fields of:

  • Soil analyses
  • Geotech (shrinkage and swelling clays / building)
  • Exploration resources – hydrogen, O&G, water, storage
  • Quarry & Mining


We realize quantifications of chemical elements on powders or rock samples, including Li (by XRF or LIBS depending on the targeted elements) We also deliver chemical mapping on rock samples or thin-sections (MEB EDS / LIBS / microXRF).

Applications to the fields of:
  • Polluted sites and soils (copper, lead, cadmium, etc.)
  • Exploration and mining research (uranium, lithium, cobalt, titanium, etc …)
  • Exploration resources – hydrogen, O&G, water, storage – Chemosterring
  • Diagenesis / Mineralogy given its good sensitivity to light elements (H -> Mg)

High resolution imaging

Similarly to the pages of books, rock samples record crucial geological information. From the genesis of rocks to the phenomena that modify its initial characteristics, the understanding of rock’s geological history permits the prediction and exploitation of their properties. Part of this information is visually acquired by macroscopic and microscopic inspection.

However, certain industrial processes limit the access to this information. The storage of original cores can be costly over a long time-period, mainly because it needs specific storage conditions to avoid core alteration, and geological cores may be thrown away. Mechanical, petrophysical, mineralogical and chemical analyses are destructive methods requiring sampling. Access to cores may be time-consuming as they are available on well / storage sites.

HICA provides digital models of cores for the numerical storage of geological information. It also gives access to geological information outside from their storage location.


  • HICA enables the production of 3D models of geological samples with a resolution of 20 µm / px
  • Image processing solutions are available for the mapping of samples and calculation of geological parameters
  • The resolution, time of analyse and post-processing image treatments are scalable depending on your problematics

Particle-size analyses

Granulometric studies permit to determine the size-range of particles in a sediment or a solution.

A statistical representation of the different size fractions is realised (median, standard deviation, deciles).

Analyses and results are performed using european standards NF EN ISO 13503-2.
Particle size analyses can be combined to petrological descriptions and/or mineralogical analyses in order to determine the nature of the clasts composing each fraction.


LIBS - Laser Induced Breakdowm Spectroscopy

The LIBS Z-300 GeoChem Pro portable analyzer measures major and trace elements of rock or powder samples (after grinding and confection of pellets). It can be used in the field, at well sites or in the lab.

The LIBS Z-300 GeoChem Pro detects a wide range of elements, from hydrogen to uranium. It constitutes a good alternative to XRF analyzers, which have poor detection thresholds for light elements.

The LIBS analyzer is able to detect lithium, beryllium, boron, carbon, fluor and nitrogen. Good detection thresholds are observed for magnesium, aluminum, silicon, potassium and calcium, which considerably improves XRF measurements.

The LIBS analyzer is equally able to realize basic maps on small surfaces.


Mineralogical analyses are performed using a D8 Endeavour X-Ray Bruker AXS diffractometer.

The characterisation and semi-quantification of minerals can be realised on bulk samples and on the clay fraction (< 2µm). 

Randomly oriented powder mounts are prepared for bulk mineralogical analyses.

The < 2µm fraction is collected after lab preparation. Clays are mounted on oriented aggregate slides. These slides are submitted to an ethylene glycol treatment and to heating for the identification of clay minerals.


Petrographic analysis of solid rock samples are performed on thin sections using a microscope E200 MV Pol D NIKON equipped with a DELTAPIX Camera of 6 MP.

A coloured resin is used for the visual inspection of pores. Post processing treatments of images allow the quantification of surface porosity.

Thin sections can equally be stained with ferricyanide-alizarin for the observation of Fe-rich and pure calcite or dolomite phases.


Our petrographic studies are performed following the European standard NF EN 12407.

Trinocular magnifier

Petrographic analyses of cuttings and non-consolidated samples are performed under a trinocular PERFEX ZOOM PRO 10.26 S equipped with a DELTAPIX Camera of 6 MP.

Scanning electron microscope (SEM)

The JEOL JSM-IT 100LA Scanning Electron Microscope is able to provide images of solid samples at magnifications of x5 to x100 000.

It is equipped with an EDS probe, allowing the quantification and the mapping of the main elements contained in the geological sample.

Sieve shaker

Particle size analyses of non consolidated material are realised on an ANALYSETTE 3 PRO sieve shaker. It is equipped with 16 sieves for the separation and weight of the size fractions between > 32 cm and < 2 µm.
