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.
