First Geolas offers detailed petrographic descriptions of any rock samples, using our in-house Leica DM2700 P petrographic microscope. Petrographic descriptions improve the understanding of the lithological and alteration features, structural, deformation and mineralization characteristics, and paragenesis of mineralized systems. We work closely with local sample preparation labs and deliver comprehensive reports to describe the transmitted and reflected light microscopic features, to provide a finer scale insight on field and drill core samples.
