the garnet in my user pic

kareinaToday I finally wrote up the results for the garnet in my user pic. It comes from the Mt. Mary area. It has a very different composition to the garnets from the other regions of Tassie, but I like it because it is pretty. The photo is a back-scatter electron image made on the microprobe (the heavy elements are bright, the light elements are dark, and the in-between ones are in-between), which is why it is black-and white, but it shows the detail very well. The black spots in the middle of the garnet (grey) are quartz inclusions, and their swirly pattern is due to the pattern of the minerals which were present when the garnet was growing. The central portion would have formed first, then the outer portion grew quickly around the older garnet and a bunch of quartz as well.
Describing the sample and summarizing the results gave me 824 new words for the thesis, and 3 new figures, which is better than yesterday, but not, perhaps, as many as I should be doing. However, some of the figures took a while to do. I am really loving the ability to overlay images in GoogleEarth. It is so nice to take the map with sample locations marked and overlay it on the satellite photos--it gives a *much* better understanding of *where* than just the map does! (and made it possible to do the above pin-in-the-map link, by comparing the satellite photo there with the GoogleEarth image.
Other than a short walk to the local waterfall with![[livejournal.com profile]](https://www.dreamwidth.org/img/external/lj-userinfo.gif)
