back in the swing of working
Since we got home from our road trip on Friday evening, but it was a holiday weekend my transition back into working was... gradual.
Saturday we got the car unloaded and did a bit of work spackling the wall in the cellar where we will put the new shower. It is starting to get closer to smooth--one day we will actually be able to get tile on it...
Sunday was mostly relaxing, baking, reading, naps, playing Qwerkel.
Monday, even though he was home from work, it being a holiday, I still managed nearly five hours of thesis related work while he watched movies or something in the next room.
Today I got off to a slow start. I worked a couple of hours, and then needed a nap, after which I managed about 45 minutes before getting hungry and spending nearly 2 hours on a lunch break (looking at FB while eating is fun, but tends to take more time than the eating part does), followed by another half hour work before I needed yet another nap. That last nap, however, did the trick, because when I sat down to work again (just after Keldor got home from work, and curled up to nap on the couch next to me) I managed nearly five uninterrupted hours of work (I didn't even notice him get up from his nap and go to the other room).
Then he came in and suggested that it was time for our daily sword practice, which we followed with a quick acroyoga session, a session of Bring Sally Up. I did abs/boat pose for about a third of it, then switched to pushups as I couldn't do more abs, then switched back to abs at the end as I couldn't do more pushups--he did the opposite, alternating two sets of pushups with one of abs. Clearly, it has been too long since we have done that workout, as we used to be able to one exercise for the whole three minutes, and then follow it with another set with the other body part. Then we did 15 minutes of yoga (Yin, with the twists boost).
The clock indicated that he should have gone to bed after yoga, but he'd been watching a documentary on Genghis Kahn, and wanted to see a bit more, so I returned to the computer and finished up the last few tasks for today's sample, bringing me to an 8.5 hour work day to take one sample from zero data processing done to figuring out which minerals are present and getting it completely written up, with one film, two figures done (one of which is the final scene in the video, the other of which is here).
The sample write up, for anyone who wants to read it:
M26
This map is from sample RC180405, which is described as a sample of “Trondheimskleber”. When Nidaros Cathedral Restoration sent this to me they said:
“One of two of our medieval quarries: - Trondheimskleber: this sample is taken from an original medieval stone: the soapstones from the two medieval quarries Klungen and Bakkaune (Trondheim kommune) look very similar and are hard to differentiate. We didn’t manage to see from which of these two quarries the stone was taken from.”
I don’t have any other samples from Bakkaune quarry, which is located in the heart of the city of Trondheim. However, M23 comes from Klungen.
This map measures 300 x 260 µm, centred on a group of small, often inter-connected crystals, which range from ~10 to 50 µm wide. These crystals are mostly Fe-oxide, with trace amounts of V (Figure 5.3.11-A and Video Spinel-M26), but one of them is a small grain of spinel, which measures ~ 50 µm wide, also contains Cr, Co, Zn, and Mn. These crystals are too small to show the sorts of spinel zoning and Fe-oxide overgrowth such as appears in maps M18 and M19. However, it is likely that this is another example of inherited spinel being partially replaced by Fe-oxide during. Also present in this map are talc and chlorite (Figure 5.3.11-B).

Reflected light and false colour images of sample M26 (Klungen or Bakkaune quarry) showing relative variations of composition across the crystals. There is one small spinel crystal which is enriched in Cr, Co, Zn, and Mn. The remainder of the grains are Fe-oxide (also enriched in V), talc, and chlorite. From left to right. and top to bottom, the elements displayed are: Cr, Fe, Co, As, V, the reflected light image of the sample, Al, Zn, Ni, Mn, Ti, and Mg. These elements were chosen because they are the ones which most clearly show the differences between the mineral zones and/or mineral phases, or because they do not for this sample, but do for other sample(s) that contain spinel.

Caption for Video Spinel-M26:
This video shows first the locations of both Klungen and Bakkaune quarries (since it is not know which of these two the sample came from), and then fades at ~0:10 seconds to show hand sample itself (RC180405). The image is then replaced (~0:12) by a reflected light image of the spinel crystal analysed as map M26, followed by a series of element composition maps showing the distribution of each element across the map area.
The darkest purple indicates very low (or absent) concentrations. The concentration of the displayed element increases as the colour changes across the spectrum from purple through blue, and the brightest cyan tones indicate very high concentrations of that element (with respect to amounts measured on this sample—for the trace elements the total concentration may still measure only a few ppm in the crystal areas that are much higher in concentration than the rest of the map).
The sequence of element maps for this video is: Cr (~0:14), Fe (~0:17), Co (~0:19), V (~0:22), Al (~0:24), Zn (~0:26), Mn (~0:28), Mg (~0:30). Then the reflected light image of the crystal returns at ~0:34, before fading to a collage of all of those maps surrounding the reflected light image, plus the addition of maps for Ni, Ti, and As, as these are elements which feature in the videos for other spinel samples.
Just after I started typing this, he came in to say he was on his way to bed. Sleep sounds like a good idea, so I will leave this here. I promise not to share the whole thesis as I write it, but thought that a little glimpse would be reasonable to post, since, when not distracted by SCA stuff, thesis writing and the assiociated data processing is my main activity these days.
