Top: Exhalative massive sulphide mineralisation. Beige is quartz, yellows are pyrite and pyrrhotite, purples are sphalerite and galena.
Bottom: Garnet sillimanite schist. Brown is biotite, blue is sillimanite, red is garnet.
The versatility of automated mineralogy means that our analysis can be applied to a diverse range of disciplines including igneous and metamorphic petrology, sedimentary petrography, environmental and forensic geoscience amongst a host of others. Indeed, automated mineralogy is the core analytical method in many of the commercial and academic geoscience projects that we are involved in (see Publications below).
Projects can be commercially focused (e.g. paragenetic and provenance studies) or more detailed academic investigations (e.g. characterization of volcanic aerosol particulates, or arsenic precipitation on contaminated industrial buildings).
We actively support academia through discounted analysis rates, consultancy, and mentoring.
Please contact us for further information on how we can assist your projects and research.

Publications
Vidence is proud to work closely with our industry and academic partners on a range of projects. Our team actively participates in, and supports, research in a range of has subject areas from sedimentology through to archaeology. A selection of publications that our team has been involved with are listed below and cover three main areas:
Industrial, Environmental, and Forensic Geoscience
We thank all of the authors and co-authors involved and look forward to collaborating on future projects.
