Analytical Petrographic Services
In addition to providing the research, development, and quality control for
our full service thin sectioning, Spectrum's geological staff also provides a
variety of analytical petrographic and consulting geological services. By virtue
of our staff's experience, standard analytical petrography is strongly geared
toward economic geology.
- Standard Petrographic Analysis includes: (1) rock name and
interpreted protolith; (2) visually estimated modal mineralogy; (3) primary
textures and structures; (4) secondary textures and structures; and (5)
relative timing of formational events with emphasis on alteration and
paragenesis.
- Standard Digital Photomicrography includes: (1) a 3X macro photo of the
chip's polished surface; and (2) one or more photomicrographs at 28X to 568X
to document typical appearance and important features. Photos are also available as either 4 x
6 color prints or 35 mm color slides.
- All other analytical petrographic services (point counting and
non-standard photomicrography) are performed on an hourly basis.
- When appropriate, we would be happy to refer you to other experts in the fields of
microprobe analysis, X-ray diffraction, fluid inclusion studies, and
chemical analysis.
