Potash mine photo tour

On Friday, Matt and I went on a tour of the PCS potash mine in Penobsquis, New Brunswick, as a precursor to the 2011 Atlantic Geoscience Society Colloquium in Fredericton.

The evaporites of the Early Carboniferous Windsor Group were formed as a result of two marine incursions into an otherwise clastic red bed sequence within the Moncton sub-basin. The evaporites containing the potash ore have been folded into a NE-SW trending anticline as shown in the diagram below.

Brian Roulston hosted 24 visitors into the mine. We were lowered about 400 m down to the main workings then driven approximately 10 km underground to three main attractions: a cavern stope in the Basal Halite; an active stope in the halite; finally an active stope in the potash ore (sylvinite).

Thanks to Brian and his team at PCS for putting this tour together for us, it was so much fun.
