  • Minfile Nts 082Ese - Grand Forks
    MINFILE NTS 082ESE - GRAND FORKS Original release date: 1997 Researched and compiled by: B.N. Church and L.D. Jones The Grand Forks map area, located in south-central British Columbia, contains 261 documented mineral occurrences, including 108 past producers. The map area includes the historically important Greenwood mining camp, which continues to attract exploration interest and activity. Physiographic domains include the Okanagan Highland over most of the map area, and the Selkirk Mountains to the east of Lower Arrow Lake. The map area lies in the Omineca tectonic belt, which formed in Early to Middle Jurassic time as a result of the accretion of Paleozoic and Mesozoic oceanic and arc rocks of the Slide Mountain and Quesnel terranes. These terranes were delaminated from the oceanic lithosphere and stacked against the continental margin of the North America craton. The resulting calc-alkaline plutonism created a large number of Middle Jurassic intrusions of intermediate composition. These intrude the accreted terranes and the Proterozoic pericratonic Monashee Complex. Overprinting by Cretaceous Laramide and post-Laramide Tertiary transtensional structures has complicated the geology. Paleozoic age, unconformable bedded assemblages include the Knob Hill, Attwood and Anarchist groups. Knob Hill Group is Permo-Carboniferous, and possibly as old as Devonian, and consists of massive and banded MINFILE NTS 082ESE - Grand Forks metacherts and lesser amounts of quartz chlorite schist, amphibolitic schists and gneisses, and limestone bands. The rocks have been affected by deformation and metamorphism causing recrystallization and the development of foliation, quartz sweats parallel to foliation and much deformation of individual beds. The Attwood Group is Permian and consists of black argillite, sharpstone conglomerate, greywacke, limestone lenses and metavolcanic units.
