QFR ratios of sediments

I found the pictures I took of our sediments when we were analyzing QFR ratios to be really cool. Using my microlens, I was able to use my smartphone camera to focus on the sample. It’s cool how the optics only allowed the image to focus on the center of the sample, giving the image a really cool effect. The detail on the quartz grains was very interesting, as many of the samples were almost pure. That being said, It was very difficult to find a sample of feldspar without any impurities.
