Trace elements in magnetite from porphyry Cu–Mo–Au deposits in British Columbia, Canada

Mercury and other trace elements in farmed and wild salmon from British Columbia, Canada.

The present study reports measured levels of Hg and other trace elements in commercial salmon feed; farmed Atlantic, coho, and chinook salmon (n = 110); and wild coho, chinook, chum, sockeye, and pink salmon (n = 91). Metal concentrations in farmed and wild salmon from British Columbia, Canada, were relatively low and below human health consumption guidelines. Methylmercury in all salmon sample...

Late Cretaceous Volcanoplutonic Arcs in Northwestern British Columbia: Implications for Porphyry and Epithermal Deposits

Porphyry Cu and epithermal deposits are spatially and temporally related to specific volcanic and plutonic rocks emplaced during the formation of long-lived magmatic arcs formed along convergent plate boundaries (e.g., Sillitoe, 1972; Sutherland Brown, 1976; Titley, 1982; Sawkins, 1990; Bissig et al., 2003). Recognizing the presence, types of deposits, and age of the mineralized volcanoplutonic...

Porphyry Cu-Au Deposits of the Iron Mask Batholith, Southeastern British Columbia

The Iron Mask batholith is lo cated 10 km south west of Kamloops (Fig. 1). It is the source of Cu-Au-Ag pro duced from por phyry de pos its such as Afton, Cres cent, Pothook, Ajax West and Ajax East, as well as struc tur ally con trolled Cu-mag ne tite veins (Iron Mask, Makaoo, Grey Mask). Cur rently, it is the tar get of ex plo ra tion for Cu-Au-Ag-Pd min er al iza tion by DRC Re sources at th...

Characterization of Legionella Species from Watersheds in British Columbia, Canada

Legionella spp. present in some human-made water systems can cause Legionnaires' disease in susceptible individuals. Although legionellae have been isolated from the natural environment, variations in the organism's abundance over time and its relationship to aquatic microbiota are poorly understood. Here, we investigated the presence and diversity of legionellae through 16S rRNA gene amplicon ...
