Cutting Through the Last Months of 2020: Rocks, Rules, and Routine

0 Cutting Through the Last Months of 2020: Rocks, Rules, and Routine

I returned to Chicoutimi and my student life fully revitalized after four weeks of field work in the north. Revitalized in the sense of normalcy within the bleak year of 2020. The harsh lockdowns of the previous months had drained my willpower, but that stretch in the field rekindled something. A sense of momentum. Of purpose.

On a late-summer’s day, somewhere in Chicoutimi

September had arrived and the academic year had begun. The university was slightly more open now. Masks and distancing were still in place, but at least there were people in the halls again. Some recreational spaces reopened too, including the gym I had signed up for. Slowly, it felt like we were climbing out of the lockdown haze.

Back to the grind

With the amount of material Alexandre and I brought back, we had months of work ahead. All those rock samples needed processing. Cutting them down, preparing them for thin sections, and eventually for geochemical analysis.

We both had prior lab experience and felt confident going in. The lab manager walked us through the equipment. A couple of fixed rock saws, a discussion about blades. Alexandre asked David, the lab manager, for the best blades since our samples were granitic, quartz-rich, and extremely hard.

David gave us the “student treatment.” He didn’t trust us with the sharper blades and handed us the smoother ones instead, telling us to just take more time. Not a great start.

After a single day it became obvious those “safe” blades weren’t going to cut it. Literally. We were standing there for hours, barely making progress. Eventually David gave in, and from the next day on we were allowed to use the proper blades.

That solved one problem, but another quickly appeared. Even with the right blades, the machines kept shutting down under strain. David explained the fix involved flipping a breaker switch in an electrical box, but according to protocol, he was supposed to call an electrician to do it.

For us, this was next level. Calling an electrician just to flip a switch? How did anything get done? It was the complete opposite of the fix-it-yourself mentality we grew up with in Europe.

Outlaws in the lab

The work settled into a routine. Daily sessions of rock cutting. Alexandre had far more to process than I did, seventeen buckets compared to my five, so I helped where I could.

The breaker issue quickly became unbearable. It would trip multiple times a day, and David wasn’t always around. Sometimes we’d be stuck waiting hours just to continue working. Then came the day he wasn’t there at all.

Within the first hour, everything shut down again. That was it. Alexandre had had enough. The electrical box wasn’t locked, just braced. He opened it, flipped the switch, and closed it back up. We were back in business. Outlaws at work. And we got a lot done that day. No more waiting. No more interruptions. Just progress.

By late afternoon we were exhausted but satisfied. Then I noticed something that instantly killed the mood. A small ocean had formed in the lab. All the water from the saws hadn’t been draining properly. It was pooling in the center of the room and slowly creeping toward David’s office.

We were screwed.

The Great Flood scandal

The design of the room made no sense. The lowest point was where the water pooled, while the drainage grates sat slightly higher. It was absurd.

So we grabbed the wide navy brooms and started pushing the water uphill toward the drains. It took over an hour. By the end, most of it was gone, but the floor was still wet and muddy. We were completely drained ourselves, so we decided to leave it overnight and come back early to finish.

The next morning was a disaster. David was furious. He wanted to ban us from the lab. Alexandre had already taken the initial hit before I arrived, and Lucie was there trying to mediate. We explained the drainage issue and what had happened, but there was another problem. He had found out about the breaker.

Illegal. Catastrophic. Students flipping a switch. Endangering everyone. You get the idea.

Lucie was more understanding. She had grown up in France and shared our mindset. Later she even told us she once got scolded for changing a light bulb herself instead of calling an electrician. Canada… what the hell?

Yes, it sounds ranty. But that’s exactly how it felt. The whole situation was absurd. We were put in time-out. Not for long though.

Once David ran the saws himself, he quickly realized the drains were clogged. That was the real cause of the flooding. Not us. We were eventually pardoned, with one condition: stay away from the electrical box.

Fair enough. Luckily, thanks to our “outlaw day,” we could afford to slow things down.

Better days

By October we were finally done cutting. The samples were sent off, and the next phase began. This was my favorite part.

Thin sections opened up an entirely new world. What looked simple in hand sample became incredibly complex under the microscope. Beyond quartz, feldspar, and amphibole, there were all these accessory minerals. Titanite, apatite, sulfides, magnetite, zircon and more. Zircon was of particular interest for us. Its resistance to alteration makes it ideal for dating. Tiny crystals carrying time itself. You could get a surprisingly accurate idea of when the host rock formed.

I was equally interested in apatite and sulfides. Some for thermometry and barometry calculations, others just out of curiosity. This was the kind of research I loved. Digging into complex methods, trying to reconstruct pressure, temperature, even oxygen fugacity of ancient magmatic systems. From that, you could infer things like the potential of a magma to transport gold.

It was precise and logical, yet somehow felt like science fiction.

Remote science in a strange year

Restrictions still made things complicated. For laser ablation work, we used the LA-ICP-MS at Laurentian University in Sudbury. Their setup was more powerful than what we had at UQAC. The lab manager, Jeff, was fantastic. After a short introduction, he trusted me to book and operate the system remotely. It was a pleasure.

However, not everyone was that flexible. The microprobe lab in Quebec City refused remote access entirely, despite my prior experience from the University of Copenhagen. In doing all of the work themselves, their schedule was very limited and it took a very long time for me to get my results. Everyone was adapting differently to the new world of restrictions.

Still, those final months of 2020 were good for me.

“Laser time” became something I genuinely looked forward to. I would spend entire days in Lucie’s lab, remotely running analyses on my samples in Sudbury. One of my favorite tools was the EDS system. Quick, on-the-spot chemical readings. Not as precise as the laser, but perfect for identifying minerals and satisfying curiosity.

I’ll never forget December 2020. That’s when I identified a rare fluoro-carbonate mineral as parisite. High in rare earth elements. My first and only truly exotic find using EDS. Another memorable moment was spotting thorite inclusions inside zircon grains that looked completely destroyed from within. A perfect example of metamictisation. Radiation slowly breaking down the crystal structure over time.

These were my small discoveries. Quiet victories in a microscopy lab, with avant-garde progressive metal playing in the background. Some of my best memories from UQAC.

A quiet, uneasy ending

But December also brought a tightening of restrictions again. A new COVID variant, renewed panic, and Quebec shut things down once more. Non-essential services closed. The gym, which had kept me active and sane, was gone again. A curfew was introduced. Christmas gatherings were effectively cancelled.

After nearly a year of this, we had enough. Restrictions or not, Alexandre, Pedro, and I decided to meet for a turkey dinner at Pedro’s place.

I remember how dead the streets were that evening. Even by Chicoutimi standards, it felt eerie. Snow-covered, silent. Curtains drawn everywhere, as if people were hiding how many guests they had inside. It felt like everyone was quietly rebelling, but also watching over their shoulder.

The idea that you had to hide a small gathering from the authorities was… surreal. Still, we had our evening. We caught up. We laughed. For a moment, things felt normal again. 2020 was coming to an end, and we allowed ourselves a bit of hope.

Surely 2021 would be better. How much worse could it get?

Right?
…Right?
Wrong.
