It’s almost time for the Brantford Gem and Mineral Show held every year the first of April. Three years ago when the theme was calcite, the University of Waterloo had a display of some unusual calcite specimens.
What you see here are the effects of calcium carbonate build-up over time. The copper pipe filled with layers of the stuff is about 8″ in diameter. The stalactites form the same way. Calcite slowly builds as it precipitates out of the groundwater. Reiner and I came across a section of tufa along the Nith River. It had washed out in the spring floods and exposed cavities within. You can tell that the formation has moved more than once by the way the stalactites flow in different directions. I found this particular monstrosity and carried it out. I have the chiropractic bills to prove it!
