AbstractThis 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.
