Thin section petrographic analysis for clastic limestone rocks Similar appearance of PPL (left) and XPL (right) as a specific characteristic of a carbonate rocks thin section
- 5. 1: Sandstones - Geosciences LibreTexts
In thin section, if the quartz grain is made from a single crystal (monocrystalline) it will appear clear white in plane polarized light (PPL) and uniformly go extinct every 90° in cross polarized light (XPL)
- 26632 Climax Suite (XPL + PPL) - Virtual Microscope
This collection of virtual thin sections is the result of a collaboration between earth scientists at Leicester University and The Open University The collection consists of 135 slides from the Leicester teaching collection, including igneous, metamorphic and sedimentary rocks
- Thin section images of hand samples and drill core from mafic . . .
The images of the entire thin section, in plane-polarized (PPL) and cross-polarized light (XPL), were taken using a high-resolution digital camera on a macro stand

Examples of sandstone textures, identification, and description in thin section and under a polarizing microscope
- Thin section - Wikipedia
In optical mineralogy and petrography, a thin section (or petrographic thin section) is a thin slice of a rock or mineral sample, prepared in a laboratory, for use with a polarizing petrographic microscope, electron microscope and electron microprobe
- Thin section analysis - AAPG Wiki
The number of points counted per thin section, and therefore the labor intensiveness of the analysis, depends upon the precision required For most applications, at least 300 points must be counted per thin section to ensure an acceptable level of precision
