The images presented here are overlaid paired scans of my teaching collection of “exotic” rock thin sections. The left image is the sample in unpolarized light (having found a new thinner polarizing film, samples from 2022 onwards will be scanned in E-W plane-polarized light… see below for details); the right image is the same view under crossed polars. The image pair features a central slider that can be moved left or right to compare specific features under either light condition. In some cases, an additional scan or photo will follow the first image pair, for example, to show the N-S plane-polarized view for strongly pleochroic samples, or to show photo under UV for fluorescent samples, or for some other illustrative purpose.
The featured samples illustrate some of the mineralogical & compositional diversity of a variety of unusual & uncommon igneous, metamorphic, and metasomatic rocks from around the world. The minerals included in my three-volume series of optical mineralogy e-books were photographed from among the first 100 or so of these particular thin sections. Indeed, with a bit of searching, the specific photographed grains can be located in these wider-field scans, providing an even fuller petrographic context to the e-book photos. A detailed figure caption follows the images and presently includes:
(1) the thin section number. All but one of the thin sections are FKM series; in the cases where source material for the billets was sampled from the research collections, or was donated or gifted to me by colleagues, that information is noted.
(2) the sample locality. For most samples, I’ve added a link to the location description on mindat.org, which provides useful additional information on associated minerals, geologic environment, map coordinates, and locality & specimen photos. A few samples are from unknown or presumed localities, and are so noted.
(3) a descriptive rock name, followed in most cases by some additional petrogenetic interpretations (to be improved over time as I learn more about each sample).
(4) a summary of major minerals present, and any distinctive special textural relationships, such as symplectites, veins or alteration. In some cases, I’ve added some of my own analytical data to highlight notable compositional features of specific minerals, or alternatively, to describe the distribution of certain rare elements among multiple minerals within an unusual bulk composition. Check out the microprobe analytical routines page to see the optimized set of major, minor and trace elements sought for different mineral groups. For certain samples, this section also includes notes about how some of the minerals were normalized (including assumptions or estimates); notes on the crystal chemistry, P-T-X conditions of formation, and/or nomenclature (with external links, when available); and also any relationship to other samples in this collection (with internal links).
For some samples, (5) accompanying videos, including a table of important minerals in the sample, with descriptions of color/pleochroism in PPL, and birefringence in XP. Video coverage is in the early stages and should expand with each periodic update. These optical details to make it easier for viewers to pick out specific minerals in the images, and also in their own samples. I’m also in the process of adding detailed tabulated mineral composition data for the thin sections I’ve been able to take to the microprobe (at this point, roughly half of them). Compiling these tables will be slow going, so check back periodically to follow my progress.
The originals of these scans were captured as TIFF files with a CanoScan 9000f Mark II scanner at 2400 dpi using positive color film mode, with subsequent post-processing in Apple Preview to improve white balance, exposure, sharpness, and resizing to 3300 x 2100 pixels (for an individual file size of ~27 MB… yes, these are a bit unwieldily large!) Each thin section was first scanned in unpolarized light and then again between two sheets of crossed polaroid film aligned parallel to the thin section edges. Originally, “plane polarized” scanning in separate E-W & N-S orientations was attempted to highlight pleochroic variation, but this ultimately had to be abandoned due to significant (and very unsightly!) stray polarization effects [update: in July 2022, I tried out a much thinner polarizing film (0.22 mm) that apparently doesn’t produce a noticeable stray polarization. So for samples FKM-341 onwards, the left-hand scan image no longer uses regular unpolarized light, but is now a true E-W plane-polarized light scan. For occasional samples where only a single pleochroism color is observed in a mineral of interest due to preferred orientation (e.g. the mostly same-oriented serendibite in FKM-371), I’ve added a separate, additional N-S plane-polarized scan to highlight a different pleochroism color. Finally, for selected especially pleochroic samples added prior to FKM-341, as time allows, I’ll go back and re-scan those samples in plane-polarized light]. For the most effective outcome of the “before/after” photo plugin I’ve utilized here to produce the slider feature, I tried my best to ensure that the photo pair are similarly framed (and hence that they overlap as well as possible).
To produce manageable file sizes appropriate for web display, the original TIFF files were converted to JPG files (at the “highest compression” setting, reducing each to ~450 kB), and then set to display at 800 x 509 pixels. Despite the high compression, the images appear almost indistinguishable from the original TIFF images, at least when viewed at typical laptop (Retina display) or mobile device screen sizes; nonetheless, each JPG file is less than 2% of its former TIFF size. I’m certainly no expert at image processing for web display, and indeed what you’re now seeing is my second attempt (my first attempt resulted in noticeably “fuzzy” images). I’m open to suggestions about better ways to display high quality images at manageable sizes, but I have to say that I’m pretty happy with the sharpness of this second batch of photos. For scale, each image captures a central area of approximately 35 x 22 mm of the thin section; consequently, 1 pixel represents about 44 μm of the sample.
All of the FKM series thin sections are uncovered and polished, so quite a number have spent time in the microprobe. For those lucky samples, I typically have analytical data on essentially the entire assemblage, and will try to incorporate more of those results here as I continue to update this page. Most of the samples in the FKM series were purchased from several “rare-mineral” dealers at the various Tucson Gem & Mineral Show venues between 2010 and 2022, and from a few similar online dealers (note: identifications not verified by analytical data are based on dealers’ labels, and in several cases, dealers’ labels have been found to be disappointingly incorrect). I try to add roughly 30-50 new thin sections every year, so look for this collection to grow.
Unlike some other collections of thin section images on the web, there are few rock types represented here that would likely be covered in an “intro to petrology” course. Nonetheless, although many of the featured rocks and their constituent minerals are quite rare and unusual (and so perhaps may seem to be of little particular interest to most viewers), a number of these samples are from classic localities, a few are great examples of diagnostic optical properties such as marked pleochroism or striking anomalous birefringence, and all illustrate an interesting texture, mineral assemblage, or bulk composition. Indeed, for a few of these rocks, only a limited number of geologists have ever even seen them in thin section; therefore, I’m very happy to be able to share the images of these really “cool” out-of-the-ordinary rocks with the global online community.
Note: I currently have just over 400 samples featured here, so it’ll probably take some time to fill in all of the caption information accompanying each image (hence the “test” and “add photo(s)” placeholders currently under some samples); check back periodically to follow my progress. And finally, please remember, these images are copyrighted. Enjoy them here for their academic and aesthetic value, but please don’t copy or use them offsite without permission. If you do have a particular educational or research interest in some of the images, I’d be happy to give permission for their limited (& not-for-profit) use… just ask (you can contact the website administrator).
So, browse the pages below, or use the index search bar to find specific samples of interest based on mineralogy or other search criteria. Note: if you have a slow internet connection, it might take a minute or two to load these image-intensive pages.
index of scanned thin sections
Amending these entries (not only the “anticipated minerals” column, but also the “general environment” and “notable enrichment” columns) is an ongoing process, so look for this table to become more accurate and more detailed with time (and thus ideally more useful too).
Of course, the strength of this table is the ability to search for and isolate samples based on user-selected criteria. For samples with detailed petrographic or analytical data, I’ve formatted the mineral entries to be particularly search-friendly, by including common mineral group and series names, informal names of compositional varieties, as well as an indication of whether multiple names represent discrete phases or simply compositional gradation. The formats are:
—plain font without quotation marks: recognized species (e.g. forsterite).
—plain font with quotation marks: non-end-member varietal names (e.g. “oligoclase”), potentially new species that are not yet recognized (e.g. “SrSr-ruizite”… I’ve tried to follow logical nomenclature conventions in these cases and use established root-names with appropriate chemical modifiers), or names that are in the process of being replaced but are still in common usage (e.g. “sodic-gedrite”).
—italics font: commonly used mineral family or series names (e.g. amphibole, biotite, plagioclase).
—parentheses and brackets, except when used for Levinson suffixes, identify the specific minerals of a family or series that are present, or alternatively, note the absence or mis-identification of a species that was anticipated from the dealer label, or note some other important feature.
—a back-slash between minerals denotes a composition which straddles a nomenclature boundary, or a compositional gradation between two or more end-members. For example, the entry:
tremolite/actinolite
can either represent an essentially homogeneous composition on the Mg/(Mg+Fe2+) = 0.9 nomenclature boundary that delineates tremolite from actinolite, or alternatively, represent a zoned amphibole grading from distinctly tremolite regions to distinctly actinolite regions. Check the more detailed figure caption accompanying the particular sample of interest to determine which of these two very different situations is applicable.
—a comma between minerals denotes distinct phases within a sample. For example, the entry:
muscovite, quartz
means that both minerals are present as individual species.
In the case where two minerals seem like they should be part of a compositional gradation but are separated by a comma rather than a back-slash, for example:
amphibole [magnesio-hornblende, actinolite])
also denotes distinct phases and indicates the minerals formed separately rather than as a single zoned crystal (e.g. igneous magnesio-hornblende rimmed by later actinolite alteration).
Multiple formats may be used in combination to convey richer detail. For example:
feldspar (K-spar [Ba-rich orthoclase, microcline], plagioclase [“oligoclase”/”andesine”, albite])
indicates that microcline and a Ba-rich orthoclase are both present as distinct K-spar phases. These potassium feldspars occur with a compositionally zoned plagioclase gradational between oligoclase and andesine (or, a homogeneous Ab70An30 plagioclase), as well as an additional separate albite phase.
The preceding feldspar example also demonstrates that by using this format, a user can expand or narrow a search by selecting either a general search term or a more specific one (for example, searching for all samples containing any feldspar, any plagioclase, or a specific plagioclase composition range). Cool, huh?
Anticipated minerals listed in gray are based on dealer labels, on hand sample evaluation, or on subsequent optical evaluation of the prepared thin section; minerals listed in black have been further examined with the microprobe. In a few cases, some of the samples with minerals listed in gray have in fact been microprobed, but the data either haven’t been normalized yet, or haven’t been tabulated in the index yet. Finally, note that the listed order for a sample is not based on abundance, but rather roughly follows Dana’s classification.
