Thin Sections
At the Michigan Geological Repository for Research and Education 51福利社 Michigan University, we have an extensive collection of thin sections.
Thin sections are very thin slivers of rock (about 30 渭m thick) cut from cores. When examined with a polarizing microscope, these samples reveal the mineral composition and fabric of the rocks. That data is used to evaluate reservoir quality, environment of deposition and to compare these direct observations to porosity and permeability measurements obtained indirectly, such as by wireline logs. The MGRRE thin section collection documents over 2500 sections available for on-site viewing. You can also view scans of our thin sections on-line by clicking on the URL links in the far right column of .
