Polymetallic Deposits of Sisson Brook and Mount Pleasant, New Brunswick, Canada

Résumé du livre

"This field guide describes two granite-related polymetallic mineral deposits that have been extensively explored in New Brunswick, Canada. One is located at Sisson Brook in west-central New Brunswick and is a large-tonnage, low-grade tungsten-molybdenum-copper deposit. The other is situated at Mount Pleasant in southwestern New Brunswick and is a small-tonnage, high-grade tin-tungsten-molybdenum-bismuth-indium deposit. Both deposits are associated with similarly aged plutonic rocks but exhibit contrasting mineralization styles that reflect different physicochemical conditions of formation. The geological settings and mineralization styles at Sisson Brook and Mount Pleasant can be observed in road, power line, quarry, and trench exposures. Metallogenetic models developed for these two deposits are compared here with those proposed for other polymetallic deposits in the region."--Document.
