More specifically, this ecoregion is composed of metamorphosed Mesozoic greywacke sandstone, siltstone, and marine volcanics overlain by Miocene intrusives, Pliocene marine and terrestrial fine-grained sediments, and Quaternary lavas and pyroclastics.
-
Fumarolic activity was reported from Murdoch and Dallman cones in 1982, and fresh-looking pyroclastics and a lava flow at Dallman (not observed in 1979) were seen on the ice surface three years later (Gonzàƒ⠬ez-Ferràƒ⠮ 1983).
-
The property geology consists principally of basalts, massive concordant and discordant gabbros, and felsic to intermediate pyroclastics.

-
The Project is located within the Abitibi Greenstone Belt and hosts a thick sequence of east-west trending, near vertical dipping volcanic flows and pyroclastics of the Malartic Group (the "North Rhyolite") that also includes quartz-feldspar porphyry dykes and sills, closely associated with the lode gold vein mineralization and the, little-investigated to date, Noranda or Matagami-type volcanogenic massive sulphide (or "VMS") deposits.
-
Mineralization on the "B" Claim Block was encountered in felsic pyroclastics flanking a strong north-south trending growth fault on the property.

-
Residual vuggy silica occurrences are localized by a broader overprint of silica ± alunite, within ubiquitously argillic to advanced argillic altered rhyo-dacitic pyroclastics.
-
The property consists of metavolcanics and metasediments, comprised of an upper volcanic sequence consisting of mafic to intermediate to felsic flows and pyroclastics, with the lower sequence consisting of mainly mafic flows.

Volcanism is the ” set of geological processes that result in the expulsion of lava, pyroclastics, and gases at the Earth’s surface” and is speeled with an “o”, not a “u”
