The main stock of the Novate Intrusion partially cuts the Bregaglia Intrusion while smaller parts lie just west of it. The Novate Intrusion is younger in age (24 Ma, Liati et al. 2000) and consists of a leucogranite. Its peraluminous chemical composition suggests that this granite is not related to the calc-alkaline Bregaglia suite, but was derived from the partial melting of crustal rocks that are widespread in the Southern Steep Belt – or root zone – north of the Tonale Fault.

Grande filone granitico a due miche, grana media fino a medio-piccola, con numerosi piccole lenti o noduli di rocce ultramefiche.
