SPECTRAL EVOLUTION Participates in Petrobras University Quaternary Carbonate Course and Field Trips


Spectroradiometer capabilities demonstrated in scanning of stromatolites, microbial laminates, and evaporites



Lawrence, MA – Led by Dr. Jose Carlos Sicoli Seoane of the Geology Department at the Federal University of Rio de Janeiro, the second Petrobras University field course took place from November 10-14, 2014. With field trips to Buzios, Brejo do Espinho and Lagoa Vermelha sites, the course was focused on stromatolites, microbial laminates and evaporites as modern analogues to pre-salt oil host rock. The field course also included measuring for dolomite and signs of hydrocarbon seepage.



SPECTRAL EVOLUTION’s founder, Dennis Witz, was invited to bring a PSR-3500 full range 350-2500nm field spectroradiometer equipped with EZ-ID sample identification software and the Custom Library Builder module. The PSR-3500 was used to take a large number of scans in the field at the various locations to measure and identify aragonite, calcite, magnesium calcite, and dolomite.



Stromatolites are considered to be the oldest macroscopic evidence of early life – in essence living fossils. They are built by the metabolic activity of microbes. In the areas of study for this field course, stromatolites are composed of dolomite. For many years all dolomite was considered to be “ancient.” However, at sites like the Vermelha Lagoon, it was discovered that the activity of microbes here induced dolomite precipitation.



The PSR-3500 was instrumental in scanning all the course areas and in one beach setting showed dolomite mixed with calcite. In addition, the PSR-3500 measured photosynthetic activity in microbial mats.
