The Trans-Hudson orogen is a major Early Proterozoic suture between the Archean Rae-Hearne and Superior cratons of the western Churchill Province. Reindeer Lake transects a major portion of the Trans-Hudson orogen in northern Saskatchewan (northwest Reindeer zone). Exposed from north to south are: (1) reworked Archean crystalline basement; (2) a continental arc batholith (Wathaman Batholith); and (3) a mainly juvenile volcanic arc terrane (La Ronge Domain).
La Ronge Domain metavolcanic rocks (1910 - 1880 Ma) are characterized by arc type geochemical signatures. Compositions are dominantly mafic to intermediate, ranging from low-K tholeiitic to medium/high-K ...
