Abstract
New geological data from the Malartic composite block of the Abitibi greenstone belt indicate that this volcanic pile is composed of four distinct mafic lithotectonic domains that are overlain by a calc-alkaline sequence. The mafic domains are thought to be examples of accreted Archean oceanic plateau material that were deformed during their collage state. The younger calc-alkalic sequence represents extension-related volcanism that erupted through the accreted and deformed plateau material. The relations described here may represent a common feature of Archean terranes.
