East Scotch Settlement - BP

Annidale Belt, southern New Brunswick, Canada

Orogenic goldAu (As, Cu, Pb, Zn)

Type
Orogenic gold in quartz-carbonate veins (Appalachian greenstone belt)

Annidale Group (late Cambrian to Tremadocian, 497 to 481 Ma), Penobscot back-arc between Ganderia and Avalonia, metamorphosed at greenschist facies; auriferous quartz-carbonate veins with chlorite-sericite-fuchsite haloes, ascribed to the Penobscot orogeny and the Stewarton Gabbro (479 ± 2 Ma) according to the authors. East Scotch Settlement Formation (pillowed mafic volcanics, pyritic black shale), north of the Taylor Brook Fault: auriferous quartz and quartz-carbonate veins in sheared volcanics and graphitic shale, gossans. Pyrite, sphalerite, galena, chalcopyrite, arsenopyrite, berthierite; chip sample up to 39.5 g/t Au. Hydrothermal rutile U-Pb 505 ± 65 Ma, muscovite 40Ar-39Ar plateau 466.6 ± 4.3 Ma (Early to Middle Ordovician). Indicative coordinates (Annidale village).
