Nanoscale examinations of altered chromitite ore samples from the Black Thor deposit after dissolution experiments in sulfuric acid-bearing solutions of pH 2.5 show that clinochlore alters...

... of barren iron-sulfide xenomelts to form magmatic nickel–copper–platinum group element deposits. We demonstrate that this process is geologically, physically, and chemically feasible, that it probably occurred in the Black Thor Intrusive Complex, and that it may have applications elsewhere. Converting...

Trueman Abstract The Thor Lake rare metal (Zr, Nb, REE, Ta, Be, Ga) deposits in Canada’s Northwest Territories represent one of the largest resources of zirconium, niobium, and the heavy rare earth elements (HREE...

...Yonggang Feng; Iain M. Samson Abstract The Thor Lake rare-element (Y-REE-Nb-Ta-Zr-Be) deposit, Northwest Territories, Canada, is a world-class deposit hosted by alkaline syenite and granite and has two main mineralized zones, namely the Nechalacho and T Zones deposit. The T Zone is shown to have...

... of the Nechalacho layered suite. In order to test this hypothesis, a sample of the albitite (L08-094: 123.4) containing bladed albite and anhedral orthoclase crystals was selected for detailed study. Gallium concentrations in the Thor Lake rare metals, Nechalacho deposit, Northwest Territories, Canada, exceed...

... ( Kuiper 2003 ). There are no constraints on an upper age limit for the cover sequence, and the youngest depositional age in the Thor– Odin dome is uncertain. The basement orthogneisses are interpreted to have been igneous rocks that intruded into the basement paragneiss during the Paleoproterozoic...

..., originally deposited on top of Laurentian basement rocks. The youngest rocks are Devonian and deposited shortly before the onset of widespread Late Devonian to early Mississippian igneous activity in the Selkirk Domain or Kootenay arc. The cover sequence of the Thor–Odin dome thus preserves some of both...
