Nelson plutonic suite 

(Jurassic) 

(Southeastern Canadian Cordillera, unit Jpf)

Consists chiefly of granodiorite, quartz monzonite, and local monzonite plutons that yield isotopic ages 
mainly of 185-155 Ma local crustal inheritance. Intrudes Quesnellia and Kootenay terranes and (locally) 
North American craton margin. Emplacement was at least partly coeval with major regional compression.
