I've learned a bit about kidney stones today. They're apparently calcium oxalate. On webmineral there's no listing of the anhydrous mineral. There are however three hydrous species: whewellite, weddellite and caoxite with 1, 2, and 3 moles water each. The funniest one is the whewellite because that is described as forming in "low-temperature hydrothermal solutions...releasing methane." That sounds just like my situation :)
I took some photos of it on the microscope at school today. It certainly looks like a clump of minerals.
Clearly it must have been in me for a while to have formed that kind of deposit.
I'm supposed to take this to a urologist so he can analyze it and tell me what caused it. But, we can analyze stuff like this in my lab. We can measure calcium isotopes on the TIMS; we could put it in the XRD to see what minerals are there; as you know where there is calcium, there's usually strontium so we could measure the strontium isotopes on the TIMS. Eric suggested I should measure the strontium isotopes of it and then measure the isotopes of Rockstar (which I was drinking almost every day for a while), beer or chicken Ka Prao. I wonder what a urologist is going to measure on it.
