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.
- 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. Final reports are PDF files delivered over the internet and on CD.
- Standard Photomicrography includes: (1) a digital scan of the chip's lapped surface;
and (2) one or more digital images to document typical appearance and important features.
Images are delivered in high and low resolutions on CD.
- All other analytical petrographic services (point counting and
non-standard photomicrography) are performed on an hourly basis.
- 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.
