| Abstract | This report presents the analytical data from Pb and S isotope analyses from sphalerite and galena grains recovered from bulk till samples collected from the north-central sector of the Zama Lake (NTS
84L) and south-central sector of the Bistcho Lake (NTS 84M) map sheets, northwest Alberta. The main objective of the isotope analyses is to evaluate if the Pine Point Mississippi Valley-type (MVT) deposit could be a potential source for the
sphalerite and galena grains recovered in till. Results indicate that the sphalerite grains recovered from the till have a Pb isotopic composition identical to ore samples from other occurrences along the Great Slave Lake Shear Zone. Results from the
S isotope analyses indicate that the source of sphalerite and galena in the till is not from the Pine Point MVT deposit, but from a local source situated along the Great Slave Lake Shear Zone. The source of the sphalerite and galena remains
undiscovered but it could be from a sedimentary hosted zinc occurrence. |
| Summary | (Plain Language Summary, not published)
Data release of isotopic analyses conducted on galena and sphalerite grains recovered from till samples in northwest Alberta, during NRD Program
(2003-2007). This is a legacy data release to promote further mineral exploration, a long term outcome of the NRD Program. |
