Noranda Caldera
Archean era caldera complex in Quebec, Canada From Wikipedia, the free encyclopedia
The Noranda Caldera is a well-known large subaqueous Archean caldera complex not too far from Rouyn-Noranda, Quebec within the Blake River Megacaldera Complex. The caldera contains a 7-to-9-km-thick succession of bimodal mafic-felsic tholeiitic to calc-alkaline volcanic rocks which were erupted during five major series of volcanic activity.[1]

The metallogenic impact of the Noranda Caldera is well-known, but the importance of the New Senator Caldera and Misema Caldera remains to be evaluated.
