Sediment-hosted lead-zinc deposits: A global perspective
David L. Leach,D. F. Sangster,Karen D. Kelley,Ross R. Large,Grant Garven,Cameron R. Allen,Jens Gutzmer,Steve Walters +7 more
TL;DR: Sediment-hosted Pb-Zn deposits contain the world's greatest lead and zinc resources and dominate world production of these metals as discussed by the authors, however, these ores are divided into two broad subt)1Jes: Mississippi Valley type (MVT) and sedimentmy exhalative (SEDEX), despite the "exhalative" component inherent in the term SEDEX, in this manusclipt, direct evidence and direct evidence of an exhalite in the ore or alteration component is not essential for a deposit to be classified as SED

Textural, Compositional, and Sulfur Isotope Variations of Sulfide Minerals in the Red Dog Zn-Pb-Ag Deposits, Brooks Range, Alaska: Implications for Ore Formation
Karen D. Kelley,David L. Leach,Craig A. Johnson,J. L. Clark,Mostafa Fayek,John F. Slack,V. M. Anderson,Robert A. Ayuso,W. I. Ridley +8 more
TL;DR: The Red Dog Zn-Pb deposits are hosted in organic-rich mudstone and shale of the Mississippian Kuna Formation as mentioned in this paper, and a complex mineralization history is defined by four sphalerite types or stages.

Re-Os SULFIDE (BORNITE, CHALCOPYRITE, AND PYRITE) SYSTEMATICS OF THE CARBONATE-HOSTED COPPER DEPOSITS AT RUBY CREEK, SOUTHERN BROOKS RANGE, ALASKA
TL;DR: In this paper, the first absolute ages of ore formation for the carbonate-hosted Ruby Creek Cu-(Co) deposit at Ruby Creek (Bornite), Alaska, were provided.

Zinc isotopes in sphalerite from base metal deposits in the red dog district, northern alaska
TL;DR: In this paper, sphalerite samples from shale-hosted massive sulfide and stratigraphically underlying vein breccia deposits in the Red Dog district in northern Alaska show a range of δ 66Zn values from zero to 0.60 per mil.

Re-Os sulfide geochronology of the Red Dog sediment-hosted Zn-Pb-Ag deposit, Brooks Range, Alaska
TL;DR: In this paper, a 10-point isochron on both massive and vein pyrite yields an age of 338.3 ± 5.8 Ma and is interpreted to represent the age of main stage ore.
