Discontinuité tectonique cassante développée au bord septentrional (= externe) de la zone du Canavese s.s. Elle sépare cette dernière de la zone de Sesia. En direction du nord-est, la zone du Canavese se pince et la ligne du Canavese rejoint alors la terminaison sud-occidentale de la ligne insubrienne entre la zone d'Ivrée à métamorphisme granulitique anté-alpin et la nappe de Sesia à métamorphisme éclogitique alpin.

The intensely mylonitized Canavese Zone consists of individual slivers of basement and Mesozoic sedimentary cover rocks trapped along the Internal and the External Canavese faults between the Ivrea-Ceneri Complex in the southeast and the Sesia Nappe in the northwest, dismembered by Alpine shear zones and brittle faults. It extends from the area west of Ivrea to Locarno where it is truncated by a fault that links the Centovalli Fault to the Tonale Fault. It includes migmatitic and leucogranitic basement rocks with inclusions of mafic granulites similar to those of the Ivrea Zone, and amphibolite-facies basement rocks with granitic intrusions similar to those of the Strona-Ceneri Zone. The Mesozoic sedimentary cover can be compared to that of the Lower Austroalpine Err Nappe Complex in Graubünden and is interpreted as part of the distal Adriatic margin.

Discontinuité tectonique ductile (mylonites) développée sous faciès prehnite-pumpellyite-actinote au bord méridional (= interne) de la zone du Canavese s.s.. Elle sépare cette dernière de la zone d'Ivrée (à faciès granulitique). Son âge est plus ancien que la ligne externe du Canavese (segment SW de la ligne insubrienne).
