GENEVA MINERAL SERVICE puts an emphasis on the characterization of geological material as this is the fundament for the understanding of the properties and formation processes of geological materials.
Petrographic studies in transmitted and reflected polarized light are the most effective tools in characterizing geological materials.
For each thin section, detailed petrography is reported in a compact and easily readable form including the rock name, a brief macroscopic description, a detailed description of the mineralogy and texture (rock, ore, gangue, alteration and metamorphic minerals), and a visual estimate of the main mineral proportions (vol. %). A short discussion of the origin of the observed textures and mineral associations is included if appropriate. Photomicrographic documentation consists of at least two color pictures, with scale, legend and labels.
Detailed petrographic reports can be completed with optional studies, including systematic search and documentation of gold grains, extended photographic documentation, determination of size ranges, point counting, fluid inclusions petrography, or optical identification of magmatic plagioclase.
X-ray diffraction (XRD) and X-ray fluorescence (XRF) on whole rock samples are also offered through collaboration with the University. Other sophisticated analytical techniques are available on request.
We also offer specific reporting (synthesis, interpretation, and project evaluation), and field work.
Sample reports can be provided on demand.
